Ok I am trying to figure out where the aux power runs on my truck (06 chevy 3\4 w\ tow pakage) On the plug cover it shows what each pin is for ie. rt turn, lt turn. but the center pin for aux power for interor lights isn't marked and I don't have lights inside. so I take off the plastic cover on the back of the truck connetor and there is a green wire there but I don't know there it goes and where I should hook it to when I find it. I was thinking the rear cargo light so I won't forget it some day and come in to a dead batt.
