I am surprised no one has responded. My son's 84 Blazer's wiring is all dried up and cracked. We nursed it along, but it just gave out. Too long in the desert I guess. We will purchase the Painless #10205 harness along with a couple of extras just as soon as he earns the money. The #10205 is $450.00 before sales tax. We'll probably start in July after his first summer paycheck.
We have never rewired a vehicle. The young man is learning how to do things for himself. So many of his friend's fathers are giving them shiney, new vehicles. What a lost teaching opportunity.
I like Painless because (1) they have a harness specifically for his vehicle, (2) their wiring is labeled well, and (3) they have tech support over the phone. We will follow their instructions (already printed off of their website) and proceed methodically. All will go well.
If we get stuck, we can shoot pictures with his digital camera and email them in to discuss over my cell phone while he is under the dash. How far technology has come since I was a kid?
(Can you tell I am a mathematician / accountant by training)?
