Wiring Color Code Source.

[Rope Chucker]

I'm doing some troubleshooting of electrical problems on my '03 RAM 3500 and need a good source for wiring color codes. Any suggestions?

What I've got is no brake lights on the bed ( CM flat bed conversion) I do have a cab brake light. And the Tekonsha P3 brake controller doesn't recognize a trailer connected. BUT, I do have variable voltage at the 7-pin plug when moving the slider on the controller. AND I do have trailer brake lights.

All running lights and turn signals do work on the flatbed and trailer.

Any suggestions ?

3rd Gen Service and Parts Manuals

Already put up the 2nd gen manuals, so here is the 3rd gen installment. They can be viewed and or downloaded but the service manuals can only be downloaded, as they are about 83MB each. let me know if anything doesn't work. Enjoy 2003 DR PARTS...

The link to parts for the 2003-2004-2005 are good but I get an "Error 404" on all the service manuals. Not sure what's going on there.
