On my 09 tahoe I used a diode and made a jumper from the low beam relay to the fog light relay so when my headlights cut on the fog lights also cut on. Can this be done on my 2015? I followed a write online on my 09.

Sorry, I mis-read your post. This is for fogs on with high beams.

I’ll post my pics later. I did it with a fused jumper from a accessory source to the fog lamp fuse slot. Headlight auto feature works now with fogs on all the time.

You can locate the accessory post with a volt meter.

I got the little kit for $20 from Boost Auto Parts - really nice little kit...I know I paid $20 for something I coulda done for less than a $1 but since the Radio Shack closed near me finding a diode locally was next to impossible...so having the convenience of this kit and with the wire taps the whole install literally took 5 minutes or less and works perfectly! Not to mention their detailed videos in their site.

I am wanting the fogs to come on with low beams automatically not run all the time. With my older suburban and tahoe when the auto headlights turn on it cuts my fog lights on also.
