buy a painless wiring harness with fuse block. should run about 400. will be a cleaner install and you wont have to worry about leaving a clipped wire still "hot". just my opinion. if you dont have the cash then rip all the wires out 1 by 1 as you dont need 'em. alternator needs a sensing wire, charge wire and a ground. distributor needs a keyed hot(12v) tach and a good ground. starter needs the start wire and the big 4ga(sometimes bigger) red wire from your battery+. pretty much all you need to drive. dont rip out any of the relays or associated wires, they are probably important. can i suggest a vintage air system for your a/c? i installed one in my camaro in a weekend. so easy and simple. 1200 bucks well spent.

I would just buy yourself the wire you need and make your own harness, its much easier to tuck the wires that way and its really not that hard once you get started. I had to install an electric fan, electric fuel pump, and swap the ignition from duraspark to TFI last night and the wiring for all of it took less than an hour. Save your relays even if you don't use them, there's always something down the road that needs a relay.
