2017 GM Sierra 1500 Denali - Driver side, about by drivers door on inside of frame rail. It Y's off the harness that goes to some brake/ABS booster.
Was out hunting and found this hanging from under the truck after going through a field. Slid under but could not see anything to plug it into, so zip tied it up as the truck appeared to be running fine with no dash lights.
I got it back home and slid under it again with a light to see if I could find out where it goes, but again, cannot see anything. I slid under my buddies 2014 Silverado 1500, and his harness goes to something that has a fuel line running through it; I do not have that part on my truck. Anyone know what this is for?
