wiring diagram
 

In search of diagram than runs under raditor mine got cut off by a fan blade and like 4 of the wires are all the same color so not sure how to splice the together any thing helps thanks

What color wires are they and I will look to see if I can find them on the schematic they maybe for running lights,headlights, fog lights,etc.

Not saying they aren't the same, because they might be, but- you might have better luck in the 99-02 forum.

I'm sorry some times my mind moves faster than my fingers this is on a 1997 2500 have any of you guys replaced this harness it doesn't by chance just plug in to the main harness does it ?
