I have a 2004 ram 1500 5.7 Hemi that I'm replacing with a 2005 5.7 Hemi. Can anybody tell me if the 2004 engine wiring harness and the computer will work on a 2005 5.7 Hemi engine?

If they are both 1500 engines then they're identical, just drop in the 05 engine and plug everything in. Any harness mismatches (not likely) might possibly be on specific sensors, just use the equivalent 04 piece.
