adding a headache rack with strobes & work lights to my 2016 Silverado 2500hd WT. I have gotten a upfitter switch panel and the added wires for it. Now it says these added wires are for grounding the item I want to add so where do I ground these to when adding the lite(s). Where does the switch get its power from and how to I wire the added items? I found something about a relay under the hood in electrical panel don't understand this so can someone give me precise wiring directions as I don't want to burn down my vehicle?? thanks all

is the code easy to install or is this really a dealer item?

well at the moment the vehicle is parked until we get 4 to fix it or at least find out what it's problem(s) is/are

well I didn't record them as they only show up when refueling and go away until I fill up again so that told me that there isn't any problem until that time.

when adding fuel to our 2001 GMC Yukon AL the service engine light comes on. This is a pain in the butt having to keep going to our shop and getting the light checked and deleted. Any body got any I ideas on what causes this? Thanks for any help

thanks very much for this info. I figured it was probably that but the listing only says one instead of 2 for that part # for said vehicle. thanks again

can some one furnish me with the correct AC Delco part #'s for all four 02 Sensors. I can find 3 but the forth eludes me so I would like to start fresh with all the AC Delco OE/GM part #'s for my 2003 GMC 3500 4x4 with a 6.0 engine. thanks
