I had my 70 rr done about 3 yrs. ago,a local mopar club member that does this on the side charged me 550.00 for rewiring mine front to back.He came to my house and it took 2 days.I bought the dash harness from year one and the engine bay and truck from evans. I think all the wiring ran about 750.00.total was about 1300.00.I thought that was a good deal.The wiring harness I bought were all color coded exactly like the original,no cutting of any.year one has 30% off sale right now.do not buy painless it's cheaper but there's a reason.
