You need an ''05'' hemi engine harness the 05s are the best ones and tuning are a lot easier from what we found out, you will also need the ''HEMI'' light harness front and rear lights, I will try to get you the most info i can next week when I'm back in town the ram we did was also an 03 :-/ but it was a nice lil setup only thing is the gauges stopped working and well tranny issues

i currently tuned my truck via sct. just need ecm from an 04 4.7 for trans options. i have seen people having issues wit cluster, most having to buy a new one. not an easy and cheap route. also goin to install an lx motor. looks cleaner, especially wit an eagle manifold. iam sure someone knows how to make new ac lines and p/s lines.
