You're about to get shafted on that parts truck! Figure out how many NEW replacement parts your $3,000.00 will buy, without having to dispose of the rest of the parts vehicle, and I think you'll see the wisdom of just buying what you need. Swapping a used wiring harness is a pain, and it's probably better to buy a new one.
