Hey guys, I am stumped and need some help. I have an 03 dodge ram 2500 4wd with the 5.7 hemi engine. The engine is not original to the truck. I have been chasing some codes and the egr valve replacement has come as a recommendation. I can access the valve easy enough. Changing it out shouldn't be that hard. my problem is the wiring. when the previous owner swapped out the engine, the plug for the egr valve was not hooked up. Should be an easy fix except that the harness side plug is nowhere to be found. I can wire a new one in but I have no idea where to even begin. Does anyone have a diagram that i can reference or advice in general? Thanks in advance for all your help guys and gals.
