I used an EZ Wiring harness, but unless you really like figuring things out on your own, I wouldn't recommend it. The Painless or AAW kits are way more user-friendly. When I started the build I had a tighter budget than I do now, which is why I went with EZ.

The alternator is a CS130, which is stock in the 98 Silverado. It's not a one-wire; it has the voltage wire (the red one) and an exciter wire (the white one).

I started out thinking I would use the whole AC system from a 98 Silverado, and I bought all new parts. I was able to do some modifications to make the evaporator fit the 72 box really well, and everything looked really good until I tried to bolt the radiator support back on. The condenser was too big, so I had to go back to the drawing board. What I ended up with was a condenser and refrigerant lines from an S10. I had to rebend the lines just a little bit to get them to work, and I had to enlarge the hole in the radiator support to line them up. I'm just finishing the wiring inside the cab and hope to fire it up this weekend.
