How to do the 4 or 6 high mod on an 03-06 full size truck for $3.00

[tast101]

Brought over from TF.com

OK. Here is a right up with lots a pics on how to do the 4 or 6 high mod. I always do the 6 high cause the more lights the better and it only take an extra 2 min or so. I did this to my 03 silverado, but the fuse box is the same on an 03-06 silverado, sierra, tahoe, suburban, yukon, yukon xl and so on. So it does not matter. I did the same exact thing in the same exact places on my 06 yukon and had them on for more than a year with no trouble, would still have them If I had not traded it. OK. THe hardest part is makeing sure the diode touches some metel on the relay. We will start out with just the 4 hi mode. Some people say you can put a diode under your dash board, I tried this, im a big guy at 6'2 and it was hard for me to get in to position here, then you gotta worry about removeing the PCM thing and all that crap. This is just much easier for me.


Ok first. Open your hood.

Then find your fuse box.


open the fuse box. Find the two relays that say HdLP-high and Hdlp- low. high one is all by it self all the way to the left towards the hood of the truck. Low is second from the bottom closest to the driver fender. RIght below the low is the fog. Usually the fog relay is black while the rest are grey.

On to pics.


First remove the LOWBEAM relay. This may need plyers, I damaged mine but they still work fine (knock on wood). Put it in the RIGHT REAR socket, it wont fit in, just make sure the metel on the diode is touching the metel on the relay. Keep the grey band pointed towards the highbeam headlamp or yourhighs will be on when ever your low beams are on, if you find this, just simply reverce the diode.... sorry my first 2 pics are bad, the rest are much clearer, but you get the idea

THen put the lowbeam relay back on. were done with this one enless you did not make sure metel was touching metel here. KEEP IN MINE THE DIODE METEL SHOULD ONLY TOUCH THE RIGHT REAR CORNER DIODE PEG!!! OR NOM 85 ON YOUR FUSE BOX MAP!!!

http://i112.photobucket.com/albums/n167/fishbonejr/yes2-9.jpg



Then pull out your highbeam relay. an repeat the above step... IF you only want the 4 high mod. Just put the relay back. The DIODE end must be in the RIGHT REAR of the highbeam relay as well.

http://i112.photobucket.com/albums/n167/fishbonejr/yes3-5.jpg


IF you would like to continue to the 6 high mod ( and I know you do) Then follow these extra steps.





Remove the fog relay. Put the diode in the TOP LEFT of the fog relay. MAKE SURE THE GREY BAND IS TOWARD THE HIGH BEAM RELAY!!!! install your second diode. IF you got the radio shack ones they come in 2 packs. 3 amp 50volt resistor diodes. Re install the fog relay again making damn sure metel is touching metel and only touching that one relay peg.


http://i112.photobucket.com/albums/n167/fishbonejr/yes4-5.jpg



Then this gets kinda tricky, but after a few beers you calm down and get it done. get both diodes to touch the same RIGHT REAR peg of the highbeam relay. Then just jam in the highbeam relay, make sure both diodes are snug.

This should be your result with teh 4 high mod.

Does this work well with HIDS? awesome write up to man.

[Rollin Thunder]

should work just fine.

[Anthony]

I did this MOD and it works great, can anyone help me add my DRL to this mod too?

[OKLAGMCRUISER]

What size diode should we buy? I can't see the pics at work...sorry if the answer is within the pics.

[Rollin Thunder]

3 amp 50 volt diode is perfect. Also to do the DRL mod, Just find the DRL relay and repeat.

Ok but which Slot does it go in the DRL? There are 4

[brndns_hoe]

on the DRL relay, it's the bottom right slot as well, number 35 on the diagram, the only different is the fog relay, 35 is the top left slot...and I have 1 amp 50v diodes, they work fine as well if you can't find the 3 amp

[DenaliAK]

Just did this today in about 2 minutes. Ridiculously easy and cheap. Cost me $0.98. Radio Shack FTW! Oh, and I did the 6-high. The shop I have used in the past for HID installs would have charged me $70.00 for the "relay."

[vatahoelt]

is there a way to wire it, so that the other lights are controlled by a switch when the highs come on? i'm sure someone has probably run their system this way.

[OmarR]

Meaning....when you have your high beams on, you want to be able to alternate between 4 HIGH amd regular HIGH mode?

[vatahoelt]

Meaning....when you have your high beams on, you want to be able to alternate between 4 HIGH amd regular HIGH mode?

correct. here in VA, it's illegal to have more than 4 lights on at a time. but with the highs on, all the others turn off. i would like to have the option to either have just the highs on(for inspection) or have all the lights on at the same time.

[DenaliAK]

So, do the 4-high only. Then manually push the fog button when you want them on, too. Lots of cars automatically do the 4-high for high beams (Chevy/GMC is a little backward about this, actually), so I don't think you'd be bending any rules. Just leave your fogs off for inspection.

on 07 up it already does. But Im in va to and a cop isnt going to be able to tell all 6 are on since the low and high are so close together. Plus you turn your highbeams off anyway when close enough for someone to be able to tell.

yeah, but during inspection the inspector is going to look for the high beams to come on and the low beams to go off.

i'm pretty sure if i do the relay route with the 4 or 6 way high mod, then i could wire in a switch.

If your fogs are off, why would they care if the lows stay on or not? You are still within the four-light limit. Are they really going to go, "Hey, your low-beams didn't turn off, which isn't illegal, but they were designed to, so you fail." ???

I think that is the point we are all trying to figure out. You could just turn off the fogs with the normal switch. Do the 4-high mod, keep your fogs off for inspection, and you would fall in the 4-light rule.....

[saturday]

Hey I did this mod today and it was a snap. Thanks for the excellent write up. Now lets spend the rest of the time trying to avoid a ticket.

Go do a buddy in the inspection world if you can. My guy just slaps a sticker on and says see ya next year.

lol to a cop "well I was on vacation in va beach and noticed my inspection sticker was over due and me being the good law obiding citizen that I am, stopped at a local shop to have it done, thats why my sticker is from a va beach shop sir" lol.

I used to work at the DMV here, and you'd be surprised how many people tried to do exactly that...lol. "But I got an inspection in Florida!"

"That's great, but doesn't apply here. Each state has different standards. Thanks for visiting the DMV."

;)

[vatahoelt]

okay, so i ended up doing this. the 2 pack was $1.56 and it took me about 5 minutes to do. to make it easier, I flattened the ends with a hammer, which made it a lot easier to put them in with the relays.

i hope that there won't be any issues later on if i decide to take these out with the relays still fitting in there tightly.

[vatahoelt]

i was thinking that i probably should have soldered the resistors inline with some 14 guage wire, which would make it super easy to put into the diode peg.

[brndns_hoe]

i just stuck 'em in, no problem...was done in a couple minutes, no flattening, no soldering, nothing

$1.56?? You got ripped.....lol

Mine were $0.97 for a two-pack.

Still probably the cheapest mod either of us will ever do.

haha, yeah. i was expecting the $3 like the title said, but was happy when it wasn't. I can put the extra towards a tune. :D

[gtbigup01]

Ok so after reading through this, I still don't understand this mod or what it does. Does it allow you drive around with ur high beams on all the time for the 4hi and then Lows/High/Fogs on all the time for the 6Hi?

Question 1. Why would you want to ride around with ur high beam on, especially at nights? I can see the fogs but why high beam

[laydout97]

From the factory your low beam lights will turn off when switched to high. This mod will keep the low beams on when you turn the high beams on. From the factory the fog lights only work when the parking lamp and low beams are on. The 6 mod allows you to keep the fogs on with the high beams. Now if you only have low beams on, high beams wont work. This mod just makes all the lights work on high.

Thanks! Ive been lurking for a few days now and decided to sign up. I did a few mods to the hoe today. White 05 LT with autoride. I debadged, painted bowtie, did the 6 hi and hidden antenna mod. These have to be the cheapest mods I have ever done to any vehicle I have owned. I think i may have spent about 3 bux on all of it...lol

[fatnlowtahoe504]

if you have a 99-02 chevy you can do the high 4 for free by grounding the yellow wire on the driver side headlight.....

[denalianyone]

pretty much the easiest way

[1highbaldguy]

sweet. im going to have to try this.

does anyone know if its possible to do a 6 low mod? if so, how does the wiring go for the diodes?

[undercover_skank]

easiest and cheapest mod ever! did it today and it worked just fine. got the diodes from radio shack for like 1.50. thanks!

[firehill]

ok, sorry but maybe i missed something. Why can't the 4 high or 6 high with the diodes be done on a '02? Something different in the fuse panel?

[DenaliAK]

I'm not sure it COULDN'T be done, just that it's even easier to ground the yellow wire. Saves you a buck or two on diodes, too.

Mine's an '03, so I don't know for sure, though.

[firehill]

ok, just looked at my '02 and it doesn't seem to have a seperate relay in the fuse box for the low and high been. the only one i see was labeled "HDLP" so might have to go the cheap route of grounding the yellow wire.

[TnTahoe]

I know this is late but for the guy worried about the inspection, you could easily just take the diodes out before inspection and then just put them back afterwards

[vatahoelt]

yeah, i just say f'it and put them in. i don't get inspection for another 7 months or so.

[kickitandholdit]

i have don that under the dash but i really won those day time drining lights in the middle on too pleas let me know if it can be done thanks

[Narco]

im putting the ss bumper on so ill be losing my fogs. so if i understand this right, i would only need to do the 4 high mod correct? the 6 would be a waste. no?

[DenaliAK]

Correct. 4-high will be all you need to do.

Any chance i can get a pic of said yellow wire to ground

Nevermind, I see now.

man your such a NOOB

[dropmech]

Just did it. Neat.

[hassoun]

so i did the 4 mod on my 01 denali by grounding the yellow wire on the low beams. any suggestions on how to get the 6 mod done on my denali ? should i ground the fogs too ? or maybe wire them up to parking lights ? if so can anyone walk me through instructions ? thanks!

[dropmech]

Holy huge signature batman!

[highrollin113]

does anyone have two extra laying around and want to do me a solid and mail me two i cant seem to order to canada from the radioshack page and "the source" our old radio shack does not have the 3amp and want 4.99 for one anyway compared to 1.49 for two

[Abn Panzer]

Silly question... But Not knowing makes me nervous.

Would there be any problems if I shaved/sanded the ends of the diode's 'wires' to be thinner? I've seen where people said to jam them in, and someone flattened theirs with a hammer... what about sanding them narrower? Is there any issue that arrises with being thinner at the ends? or shaving off the outer coating of the wire exposing the copper core?

May be an obvious answer to some... just not me.

[blackbeast03]

I just did mine, took all of 5 minutes. radio shack was out of the 3amp ones though, so i used a 200v 1amp, hopefully it lasts!

[Husker1111]

just did it with 1amp 50volt and works perfect!

[Physh1]

Just did the 6 high mod today but I did do it a little different. Honestly, I didn't want to force 2 solid diode ends in with the relay pin.

I soldered jumpers to the relay pins and the relays still pop in all the way. I also used In-Sure 3-port push-in wire connectors so everything can be changed quickly. If a relay goes out it can come apart and the only thing extra to do is solder a jumper wire on the new relay.

I took a few pics. Since this is a little more exposed I also used heat shrink to cover the exposed diode leads. I got the diodes from Radio Shack...only thing with mine was the leads off the diode were waaaay shorter...another reason I went with jumper wires off the relays first.

[chip]

What post numbers are you jumping for this?

[Physh1]

On the High and Low relay jump pin 86
On the fog relay jump pin 85

[chip]

Thank You Sir!

[Physh1]

No problem :-)

[chip]

I figured out the full time fog mod too, in case anybody wants to know.

[adzam]

So I just did the 4 high mod. Worked great. I then continued to the 6 high mod and my fogs were coming on with the highs no matter if the switch was on or not. I did not like this because one of my fogs is currently not working right so I haven't been using them. So I reverted back to the 4 high mod and my highs weren't working at all! I than removed the diode, tested and everything worked fine stock. Went back to the 4 high and it worked fine again!

Anyway, I am wondering if I did something wrong with the fogs. From my understanding they should stay on with the highs if they were already on but not come on with the highs if they were off.

I have an 03 Denali...

---------- Post added at 12:53 PM ---------- Previous post was at 12:22 PM ----------

On the High and Low relay jump pin 86
On the fog relay jump pin 85

I'm a little confused now... The OP said to jump 85 on the high and low relay

[chip]

yeah. Physh1 was mistaken.

[Physh1]

I don't believe I am mistaken.

I just went out and looked at all my jumpers. From the drive side fender view of my fuse box all my relays are upsidedown. Meaning the "Orion" is upsidedown & on the lower RHS. This is exactly how things were before I did the mod & exactly how it was replaced when I was done. Every relay in my fuse box is oriented this way.

I have the wires on the lower RHS on HIGH & LOW socket pins in the box EXACTLY as the picture shows. The FOG uses the upper LHS socket pin.

As my relays are oriented all upsidedown by my pov the HIGH and LOW relay jump pin 86
& the fog relay jump pin 85.

In the pictures on page 1, the LOW relay is actually right side up and the others are upsidedown. Given the position of the LOW relay in the pic on page 1 the pin on the lower RHS would match pin 85 not 86. 86 is on the upper LHS.

I don't know if this matters but my high 6 works just fine. I wired mine based on where he said the wires went on the fuse box (lower RHS on the LOW & HIGH & the upper LEFT on the FOG).

Cameron

[chip]

Yeah, that's what it is then! I think the position of the actual relay may be inconsequential, because all of mine are right side up. So I think the important points are where the diodes should sit in the sockets, as opposed to which pins to jump.

[05nali]

i tried doing this and they both come on for the low beams and only the highs come on for the high beams. Can someone help?

---------- Post added at 07:22 PM ---------- Previous post was at 07:03 PM ----------

nvrmnd i got it, the band was facing the wrong way

[vyper202]

Did it...quick and easy...took about 5 minutes!

[oakrdrs187]

If anyone is having a problem with the fogs flash when the high beam is turned off i have a solution. I have HID Fogs and Lows and after i did this mod I noticed that when my high beams were brought from ON to OFF, the Fog lights cut out and come back due to a Small lag in current from the relay quickly switching around, so for me and anyone with and HID setup that is NO Good! SO What I did is get the diode that goes from the HI relay to fog and moved it from LOW relay to fog and the problem was solved and you have the option of driving with just fogs again. So to put it simple. follow the 4HI mod as mentioned on the thread, and for the fog, put the diode in the same place as before on the fog light side and in to your low beam relay where the high beam diode goes in, so what you will have is kind like wiring in series, diode from HI to LO and from LO to FOG.

It helped me eliminate MY fog light "flicker"

Has anyone else tried this for their Tahoe? (mine is a '99)

[TailHook]

The diode route will work, but...

Pros:
Cheap
Fast
Easy

Cons:
Fuseblock terminal stress
Intermittent connections due to "friction" fit
Diode failure
Heat (i.e. fire risk)

Since the "project triangle" concept states you can't have all three ("cheap", "fast" and "good") and being the perfectionist that I am, I went the relay route to isolate the two circuits from one another and increase safety/reliability. Obviously there is a cost/effort to doing it this way, but I have peace of mind that it's done right (according to my standards, anyway!)

Sorry Im dumb, I dont understand

[EFAJEEP]

im gonna try it this week

[05nali]

i did the high 6 mod but if I put another diode form the same fog slot as the high 6 and put it in where you put the diode in for the hi4 in the low beam would my fogs stay on with the lows also?

[chip]

Are you trying to do a full time fog mod? If so, I've done it. I can help you.

[05nali]

yes

[chip]

You can jump the relay terminals with a diode. I converted my DRLS to Amber running lights and covered my photo cell, on top of the full time fog mod. Now I have full time, full auto: Lows, Running lights (w/Amber DRLs), Projectors, and Halos (w/leds) that I wired to the running lights and blinkers, so they blink as well. I can still control my lighting: Full time, full auto with "Off", "Parking only", Parking w/ Fogs", and the 8 - Hi mod (if you count the DRLs). All in all, I love the setup. It's really effective when you're in the passing lane, or on a dark road.

BTW: I Love Your Sig!!

I've Been Wanting to do exactly what you did. I have an 01' Denali XL. Which route did you take to keep the DRL's on? Hardwire Diode From Parking lights to DRLs or Diode the DRLs to Low Beam through Fuse Box?

Thanks in Advance,

Awesome! You'll love it!

That being said: PSshhhhheeewwwww.........(thinking)..........LOL! I don't remember.

I have a post floating around here somewhere with the whole thing explained. My setup is somewhat modular, so it can (and does) change. Originally, I hard wired many of my jumps, but I have since switched to a mostly relay box based, diode jumper setup. The only thing I don't like about that, is that you kinda tear up the female terminals in the fuse box, which can lead to a power loss on the highway at night (I've had it happen). If you go the relay box route, try to find an intelligent solution to that problem. I've been working on one, but I don't have it completely figured out yet.

I have my photo cell covered up as well. That's how I got the full-time/full auto feature.

I know I'm using a diode at the box to cerate the full-time fog (with kill option) feature. You have to do this particular mod that way, because the fogs are on a 15a circuit and the hi/low circuit is 10a, and it's never a good idea to overload a circuit.

I'll have to go look at the DRLs, but I think they're hard-wired to the running lights. I'm not 100% sure about that, but I believe I did hard-wire them after I converted them to amber running lights.

What else do you want to know? Tell me what you're thinking. What do you want to do? How do you want to do it. I'll help all I can. Let's get started and make it happen.


Sorry Newb Here but would I ground the side of the wire coming from the Headlight or Coming from the Fuse box?

Thanks


It doesn't matter. They both go to the same place. Just ground it. Don't re-route it.






Oh, and Welcome BTW! This site is awesome!

I finally completed the Hi/6. Thanks for the tips and help. I decided to stick with 6 instead of 8 (DRLs), I wrote a quick write up since it took soooo long and never did end up finding a complete writeup on how to do it.

I just read it. It looks good. Only thing I would change if I were you, is change the words "fuse" to "relay". You didn't tap into the fuses, you tapped into the relay terminals.

Glad to see you got it all squared away though! Congrats.

i have an 03 yukonxl.my truck came with a separate button for the fogs,meaning i can turn on my fogs with out having to turn the lows on. and ofcourse when the hi's are turned on the fogs shut off..do i just need to do the 4 high mod or the 6 since i can turn my fogs on when ever. or will they still shut off with just the 4 high mod?

Depends what your end goal is. Do you still want your Low's to be on at the same time as High's or do you only want fogs on at the same time?

If you skip the low beam part and just wire your highs with the fogs you can do a 4 high that way. The only bad part about that is if you have HID fogs they will turn of and back on for a split second whenever you flash or use your brights. This is why some people do Fogs to Lows, the Lows to Highs so you don't get that flicker.

im putting HIDs in my fogs and lows..i would like to have all 6 lights on at once..lows,highs,fogs..but i would also like to run the fogs sometimes with out the lows or highs being on..will i be able to do that with this mod being done?

quick question....im gonna do the 4 hi on our yuk but just realized when u pull back for the "flash to pass" it leaves lows on and lets u turn highs on....if I do this so it makes them stay on using the "Forward" position of the stalk to make the highs come on, does it have any adverse affects on the flash to pass since its already designed to do this? just want to make sure if we use the flash to pass we werent going to back feed something that would fry or not...

wanna do the 4hi mod and be able to turn on and off my fogs with the stock on/off button with the hi's on. is that possible? if so can some one walk me threw it?

[rippinitup]

just did the 6 hi mod..went great. very simple. jeffyrc /\ yes you will be able to turn the fogs on or off..everything works the same, just now the fogs and lows will stay on when u turn the highs on.

So what does this mod keep the lows and fogs on at startuup (they both turn on) and will still work w/ highs? Or just that they'll stay on for highs?

Question:
I have a 2003 yukon with HIDs lows and highs, if i put HIDs in for my hi's and i do the 4hi mod....

I want my End Goal to be:

when headlights turn on i want highs and lows to turn and have the capability to turn on my fogs at anytime.

Question:
when i do this, will i have to turn on my highs for them to combo up with lows (have the indicator in my dash light up?) or will they automattically come on?

Try searching first. I've posted how I did this like 20 times now. If you can't find it, let me know, I'll help you out. It can be done.
