How to keep High Beams, Low Beams and Fog Lights 'ALL' on 2007-2014 's

I wanted to address the "How TO" for the 07-14 models. There are different procedures for other years but this one will (and does ) work. I have had mine modified for a couple of years now and is a easy modification

Thank you for this info. Looks easy enough for me to do.

 

[rdhogg]

Yep, pretty easy. It get a little tight working under the dash, but the wires are easy to get to and identify. The YouTube was perfect for my Tahoe wiring and I would think the same for you.

I'm pretty familiar with working on the BCM, as I had to replace mine and reprogram the new one with my Tech 2.

Pardon my ignorance but I dont see the video linked to your post. When I click the link i get a whole bunch of videos based on a Yahoo search. Do you have the exact link to the video? Thanks!!

This can be done with a simple jumper wire in the underhood fuse box. No need to go under the dash and cut wires.

Man, sorry I did not see your message until today. I hope you found what you needed to complete your project. If not here is the YouTube link I used:

I did not ever find any YouTube instructions that showed how to do the jumper in the fuse box. I do not like to cut wires either and the T-splice is not my go to but in this case with the limited space you are working with under the dash it is was the best solution for me.

I also used some : Tesa Wire Loom Harness Tape Used By Mercedes BMW VW Audi, that I found on Amazon for around $7.00

I'll try and remember to take some pictures of how I had it. My fogs are controlled by an aftermarket controller now but I had them jumpered in the fuse box to come on with the low beams.

Do the 'lows' and 'fog' lights stay on when you hit the high beams, and do both come on when you don't have the fog lights on and you hit the high beams? Just curious.

 

[Coolman1987us]

Yes they all stay on with high beam, all 6 lights. This mod basically runs the fogs alongside the lows. Can NOT turn fogs on or off independently. Which is why I moved to a homemade aftermarket controller.

all fine and dandy but won't work for the yukons as the high/low is a single bulb, but you can get a simple device to keep the fogs on either way

All 6 of mine are on, but I can turn off the fog lights. At night the low beams come on, the DLRs go off, but hit the high beam and they all light up.

 

[Coolman1987us]

So your fogs function normally except when you switch to high. Then the fogs come on with the highs and go out with the highs unless you've turned the fogs on with the factory switch? In which case they would stay on.

So that's a diode. Basically doing the same thing I did in the fuse box just done under the dash. Same end result I guess.

ya, and super easy to install

I agree all look like the same end result. It looks like both the diode mod and the Boost Auto mod work pretty much the same, I think. With the stock truck, the fog lights must be turned on whether it is day or night, even when the head light switch is in ‘auto’ mode. So when it is night, the headlights come on automatically and you have to manually turn on the fog lights. In this case when you hit the high beams the fog lights will go off and only the high beams go on. With the Boost Auto mod installed and you turn on the fog lights during the day, the fog lights, Parking lights and DLRs are all on, and say you flash your high beams, all the lights stay on including the high and low beams. Now when it turns night, the head lights come on and you manually turn on the fog lights, they come on with the parking and DLRs and when you hit the high beams, “all come on” the high and low beams and the fog / parking / and DRLs stay on. Now to complicate things, Boost Auto has another mod that when the headlights come on , the fog lights automatically come on, but I am not sure with this mod all the lights will stay on when you hit the high beams. Long story, the diode mod looks easier but both mods require messing with the BCM. Your fuse box mod looks the easiest.

with the fleece adapter I already linked you still have control of the fog lights as normal, except when you hit flash to pass or turn on the high beams then the fogs will come on with the high beams and if you have not turned the fogs on with the interior switch then they will go off when the high beams are not in use.

I like your mod better. Oh well I thought I did my research back then, guess not, ha

I am sure there is a multitude of ways to do it, on my 00 all you had to do was add a ground and you could have 6 high but things have changed on my 18 the headlight is all integrated inside the housing so it's all pretty complicated but the fleece module works the same on it. In both cases the yukon and my 18 silverado the headlight is a single bulb so no way to get a 6 high, fog+ high is the best it gets when you have bi-xenon or projector
