I have a 05 dodge Durango that the rest end locked up in. The 5.7 is still good and transmission as well. I purchased a 03 Ram1500 quad cab for $1,000.00 that had a bad 4.7 in it. Nice truck great condition inside and out. But I've been told its not possible, that I could use my harnesses out of my Durango since I have it all there still. Also was told to get the complete harness out of 03 1500 that had the 5.7 and it should plug and play. What harnesses do I need and anything else i'll need as well to make this swap a success.
