My dad just picked up an 2004 ram 2500 4x4 and the factory 7 pin wires have been cut and spliced into, now the trailer lights wont work. I'm guessing from the way who ever tried to splice into the 7 pin wiring to put a 4 flat on it had no idea what they were doing. I was wondering if anyone had a wiring lay out of the factory 2500 series 7 pin wires. So I can put this thing back together, as right now the wires coming from the 7 pin are about a foot long then their cut and spliced into new wires and their all the same color wire thats spliced into the 7 pin. It's like the person thought it was better to use one color 22gauge wire to splice into all the wires.


Thank You to anyone that can offer me any help.

Can anyone atleast tell me what wires go into their 7 way plug on their truck. I really need to get this wiring fixxed so he can start using the dodge to pull his car trailer. His truck is missing the plug in for the 7 way. I think the person that installed the 4 way, cut the harness off the back of the 7 way.
