I finally got around to mounting the driving lights under the rear bumper. My question is does anyone know which wire in the 7-pin trailer plug is for the back-up lights? I need that wire to trigger the relay to power the lights. Does anyone in readerland have a service manual? Thanks in advance!

 

Should be the ecnter pin. The cover over your connector will tell you that as well if it is a factory setup. It is easily checked with a volt meter as well, but I am pretty confident that it is the center pin for reverse lights.

 

Yes, center pin = reverse lights.

You may have to run a relay if the lights have a lot of output. The reverse light circuit isn't very substantial.
