You may need the entire wiring harness, ecu from the donor, plus may need to do a skim delete on the new motors ecm. I am going having the reverse done to my ram. 2005 motor into a 2007 truck. My old motor was the small 4.7 which overheated and siezed on me. I am taking everything I need from a donor truck. Having a few problems but so far other than electronics it is all going in well.
