the factory trailer harness connects inside the left rear console panel behind where the inside spare sits. ive never had the panel off to see what that looks like in there so maybe you can take a picture and show us if you like. do you have a aftermarket harness the factory harness exits the cab near the center of the rear hatch through the floor.
I do not have a harness yet nor the trailer. Im ganna going to go get one soon. May be this weekend. When i do take out the spare i will post a picture with my findings. Thanks alot for the info
Any parts store or even Wallmart should carry it.Its a little more complicated if you are doing a Travel Trailer.Like the other post says access is through the panell behind spare tire.All you have to do is to unplug the harness and plug the new one in.
