Thanks for the responses to my post. I do have the 2008 oem ram manual it just doesn't show where the rear harness connects in the front of the truck. I was hoping for someone with a matching truck who would be willing to take some pictures of the left side of the rear harness or compatible years and where it is routed to the front of the truck , so I would have an idea which way to go. I already know that I'm going to have to splice in some wires... I just need to know where abouts so I can find the right connector for the connection.
Thanks for the links-I'll check them out.
