Fogs

[Voymom]

So we traded in Phantom for a 2007 Tahoe. We were wondering if there is a way to keep the fogs on with the low beams like the 360/370 platform.

Hey! Long time since you've popped in here.

I would imagine a diode would do the trick, same as what we do for quad highs.

Likely. My 07 Silverado probably uses the same wiring scheme. I haven't looked into it yet. Actually I've owned the truck for nearly a year now and still don't know where the BCM is for sure, how embarrassing

I think regulator did his, so you might ask him.

Everything I've seen for at least the NNBS Silverado/Sierra is mods in the under hood fuse box. The GMT900-based full size SUV is probably similar.

The fogs on the GMT900 is definitely BCM controlled though, so there is still likely a way to do it there if I can find some pinouts and locations. I've just been used to not having fogs for years so it really hasn't crossed my mind to even try this yet.
