EGR valve

[muddyrock]

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.

LMAO........that's because 2003's don't HAVE EGR. Nothing to hook up. You need to delete it so your truck will run right.

should have specified. the body, frame, and i was told the harness is an 2003. The motor came out of a 2004 model truck. did the 2004 engines have one? if not, where is the best place to look for the delete kit or a plate to cover the hole when I take this off?

Even if you had a newer 2500, they don't come with EGR either. The engine itself is the same, you just have the port on the front of the head and the matching one on the intake manifold (absolutely cannot forget this ne or the engine will run like ****). Some people make their own (if you have the metal and skills); less companies are making them as the engine gets older: https://www.3rdstrikeperformance.com/index.php?main_page=product_info&products_id=7875

My 2004 Hemi has an EGR valve for reference.
