I've read on a few google results that if you buy the LED taillights, that a plug on the passenger side front above the wheel is used to connect the reverse light portion. I really dont like the LED tail lights and I don't really have that kind of money to spend on them. I was wondering if anyone knew anything about it. I'm wondering if it is the 4 wire white plug, or the two wire white plug further up towards the center. If I can figure that out, I will just add my own LED's to the back under the bed. Also, would anyone happen to know the wiring diagram on that plug? I know I can just meter the plug while someone sticks it in reverse but I was hoping to be a bit more sure. Thanks for your replies!
