I have a '99 3500 and I'm having trouble tracing the color coding for the trailer lights. Anyone have or know where I can get the truck-side color code?

Welcome to the Z. I'd suggest getting a Chilton's manual at your local parts store. Another option would be to contact the local Dodge dealer.

We LOVE pics of Rams.

Here's how to post them: http://www.ramforumz.com/forumdisplay.php?f=73

Does it have the factory trailer tow wiring?

That'll add to the challenge! :str:

First, the wiring information I have for the 2001. I believe it is the same in the 1999, but you will have to check the signals on the lines to confirm.

Left Turn - DG/RD (Dark Green/Red) - DG/BR (At light)
Right Turn - BR/RD (Brown/Red) - DG/BR (At light)
Tail marker - BK/YL (Black/Yellow)
Ground - BK (Black)

Again.....this is for a 2001 Ram, so check that the appropriate signal is on the wire before making final connection.

Hope this helps. :smileup:
