Wiring the fog lights to come on with headlights

[Mr. B]

I have a Denali, not a Tahoe, I wonder if that is the difference. You guys have separate bulbs for low and high beam don't you?

Yeah the Tahoes have separate bulbs, we however are stuck with these stupid H13's. I believe they have 9005 or 9006

I mean I suppose you could just put a few diodes straight into each the high and low beam wires and connect them to the fog lights. You can use a vampire clamp and wire it up and use Plastidip to waterproof it... it's easier than taping or shrink tubing it.

Ah, I didn't notice you had the Denali. Yeah I am not sure how those low/high bulb are wired/controlled.
