I have a 99 Ram 2500, I have a factory tow package so the wiring is made into the rear harness, what I need is to find out where the wires in the 8 prong plug in that goes to the 7 pin connector are what wires. I'm also splicing in a harness from an 03 ram and the wires some of the wires are a different color. I need pictures or a diagram for each. I'd rather see if someone can tell me what goes where, I can figure it out if I have to. I think 3 or 4 wires are the same color.

don`t know if this will help or not

I took the time today and figured all of it out. Thanks
