Car Forum / Dodge / Dodge Trucks / January 20077-Pin Hitch Wiring - Auxillary Position
Hello, I've been reading about 7-pin trailer wiring, and that is an "auxiliary" pin on them, and that it is now often used for backup lights. Does any know on a 2003 Dodge Ram 2500 if that is indeed for backup lights? -Lint For reference, what I read: (COLORS MAY VARY) PIN COLOR GAUGE PURPOSE 1 white 10 common ground 2 blue 12 electric brake 3 green 14 tail/running lights 4 black 10 battery charge (+) 5 red 14 left turn/stop 6 brown 14 right turn/stop 7 yellow 14 auxiliary/back up > Hello, > [quoted text clipped - 3 lines] > > -Lint http://www.marksrv.com/wiring.htm Here ya go.  Signature------MoParMaN------ ---Signature Pending Yet Another Assine Comment by MIANDERSON--- Thanks for the link Scott. I had actually looked at that site earlier. Unless I am missing something, I don't think it said definitely for Dodge trucks whether or not is backup. I went back and looked again, am I missing something? -Lint >> Hello, >> [quoted text clipped - 7 lines] > > Here ya go. > Thanks for the link Scott.

Yes, it's wired for backup lights. > Hello, > > I've been reading about 7-pin trailer wiring, and that is an "auxiliary" > pin on them, I have been doing the "trailer wiring" on my 2001 Dodge Ram 1500. After much research I have found that the Dodge Factory Manual simply has all the facts but they are not very specific. So I have traced all the rear wiring and made the decision to install 5 relays that are actuated by the rear wiring signals. Then I will run a fat #10 12v and a fat #10 ground stranded wire from the front to the relays. Then individual wires in a stranded cable to a metal shell 7 pin Bargman type connector. And on to the trailer. More details if you want them. Bob AZ |
