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

[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.

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?

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

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

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"

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.....

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

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!)

This is exactly what I was looking for! Thank you Sir! Very much appreciated!!

Sorry Im dumb, I dont understand

im gonna try it this week

 

[BillBlatt18]

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.

 

[BillBlatt18]

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 had it on my tahoe with all 6k hids worked like a charm just be wear the on coming traffic high beam flash and the occasional middle finger ! its awsome just recently had to take my kit off ! ****** cops gave me a ticket

 

[BillBlatt18]

Thanks chip!

can this be done to a 97 Yukon... So when you flip your high beams on all 4 comes on istead of just the 2 high beams ????

 

[chip]

Thanks chip!

Anytime Brother! Your truck looks great BTW! I don't think I ever told you that. I really like it!

Yes Sir it can.

great write up ill have to try this out! thanx Guys!

thanks again! i just put in my hid fogs and changed my hi-4 to hi-6. I will post pics 2maro. I just have to do the mod to make the fogs always stay on now

BTW, i love all of the colormatching on ur hoe, it looks sick!
