$100 a hour for labor is what I paid, mine took a little longer as I was doing a LS2 swap at the same time. Just take your time and find someone you like and are comfortable with, as a few others have said,if you can get it in writing,do. L8R ZFLASH

 

As some of the others have said, the hardest part is often thinking thru what you want and what you need. The universal harnesses all have some things that need to be relocated or added. For instance, Painless has a wire to feed power to the wipers, but they don't include the wiring from the control to the motor. Things like this can make you pull your hair out if you don't add those wires before you route everything thru the firewall and dress it out. All of the universal kits I have seen lack many of the ground wires. you will have to add them. The only tools you need will be some good quality wire cutters, wire strippers and crimpers. Maybe a soldering iron if you prefer to solder splices instead of crimping but splices. I use heat shrink on every connection for added peace of mind.

 

I did the harness myself. It was my first attempt ever at rewiring a vehicle at the same time I went from 6volt to 12volt and from a generator to a GM alternator. If you take your time, think things thru its not too hard. Where are you located? I'm in eastern PA between Lancaster and Philadelphia, I'd help you with it if your near by.

I agree I am a backyard tinkerer at best and I retired 4 trucks! It's quite easy follow instructions you will be fine

 

These trucks are pretty simple as far as circuit wiring goes. They basically have three circuits, Battery and charging circuit, lighting Circuit and starting/ignition circuit. Additional circuits such as radio and or additional accessories can be run through an added universal fuse block.
As many have already said, there are several sources that supply premade wiring harnesses both for original wiring diagram and/ or universal. When I rebuilt my first truck I made my own harness which took me about 2 days on and off. If you have the basic wiring tools and technical skills it's not that difficult.
