2002 Ram 3500 Quad cab.

Pulled the dash to replace heater core only to find the previous owner hacked up the wiring for what I think was an alarm. Then before selling he cut the system out, twisted wires together to make things work and tucked it all up out of sight.
While working at restoring to the factory diagrams I've found connectors with wires cut and two extra Door Ajar connectors. There are connectors with no pins where the manual calls for one and others that have a wire of different color than what's listed.

I have both the printed and PDF versions of the manual and have spent many hours verifying the connectors are in fact who I think they are.

My question is this: Is there a company that make a complete replacement harness?

 

Yeah, Dodge/Chrysler. Hope you have a fat wallet....

 

I can't even find a part number on Dodge sites. I'm thinking of buying a wrecked truck to use for parts. Either was still cheaper than a new truck...

 

Try to contact member Redlinear...if he's still around he has a dodge cummins wrecking yard in Arkansas...

 

Steve,
I had separated my harnesses so I could go literally from connector to connector, if I had any trouble "on the road".
Although it turned into a 6 month nightmare, I found many connectors and wires (correct color) available at several salvage yards.
