Been building gen 3 hemis for 15+ years & finally built one for myself. I have a 06 1500 2wd slt with a 4.7. I have a 04 2500 5.7 4wd donor truck. I plan on using the engine harness, throttle cable & throttle controller, motor mounts, accessories & torque converter from the donor. Several questions. Will I also have to use the harness that goes to the dash, fusebox & trans? Will either ecm work after reprogramming? Are there any pin out changes from 04 to 06. The donor truck is a late 04 with the same ecm plugs as the 06. Thanks for any info
