anybody have a

I need a schematic/wiring diagram for a 1990 Dodge Ram with the Cummins. A buddy of mine is installing one in a 1990 1/2 ton Ram to make a Diesel fun/drag truck out of and the wiring harness was burned up on the truck he took it out of so we can't tell much of what needs to be where. Neither of us know diesels well enough to know this stuff but I do know electrical very good so I know I could wire it if we just had a schematic...

BTW: He'd even buy a service manual if we could find it (as long as the price isn't insane) but all we can find is Haynes manuals and they don't have anything in them about Diesel wiring.

Thanks, Tracy
