I used these for a lot of years when I was working as an electrician.

Should be able to pick up a pair at Home Depot or Lowes.

I Installed an AAW harness in my 64.5 vert. I had done some wiring before but never wired an entire car from scratch. The AAW kit was a bit time consuming to install- with most of the time spent figuring out what was what in the box, studying the excellent diagrams and instructions they provided and then figuring out where to run everything- but once everythig was sorted and I figured out where I wanted to run the wires, the actual install was VERY easy.

You should start by lying the whole harness out on a table so you can follow the different branches and circuits and see what you will need v what you know you won't be using. 

There are at least two very excellent write-ups with tons of helpful pictures out there- one on VMF and one on CJ Pony’s site- that are very helpful and give you an excellent road map on completing the project.

I would use an AAW kit in the next car I do without hesitation, and I could probably complete the install in a day or two next time.

I bought their crimpers and, while pricey, they worked very well and IMO were worth the money.  For strippers, I just used the cheap-o strippers that have been in my box forever and they were fine.  There really aren't that many wires in kit that you need to strip and put connections on.

I've had to do a massive amount of wiring installing a Megasquirt and Microsquirt in my Lightning. These have been awesome and versatile.
