New to the group and wow all the information is overwhelming, 99 pages on towing mirrors alone.
Here is where I need some help, I have a 2018 Silverado 2500HD WT that came with DL8 Mirrors (remote adjust & heat) and I purchased towing mirrors from 1A Auto - but they will not help me with what wires to tap into to add the turn signal, running light & cargo light functions to my new truck to help me tow.
I have the mirrors installed, all the wires run through both door jams and into the cab under the dash ... HERE IS WHERE I NEED SOME HELP.
Can anyone tell me what under the dash control module, and what wires to tap into to get these new functions to perform?
The mirrors I purchased were 1A Auto TRMRP00045 which has a 4 wire harness included to use to tap into the truck,
The included wire harness has 4 wires Red = turn signals, Yellow = marker Lamp, White = Positive for high-power LED cargo spots & black = Common ground. See Below
PLEASE HELP !!!
