Been going crazy trying to figure out how to wire the a/c. The service manual has 3 different series and simply show the wires coming out of the harness to connectors. Well, my connectors have been removed on a few of them. Mainly from the harness to the generator and compressor. Any help, diagrams, etc. would be appreciated.

You have the A series. B are the large cars, F are firebirds, G are grand prix. The car has an alternator and has one large red wire in the back and a pair of wires on one connector, auto parts stores carry the standard GM connector, one large red wire and one smaller black or white wire. The compressor I believe has a connector with two wires one grounds on the compressor and the other one is hot.
That helps a bit. What I can see (the wires) - coming out of the harness below the high blower relay is a connection with 2 wires coming out. One is black with an orange stripe and what appears to be one end of a fuse connection. The other is black. A few inches further down the harness are 2 wires that look black. These are not connected. The wires to the relay are connected.
There is a set of wires coming out of the main harness that appear to be in a loop. One has a connector that looks like it goes to the compressor but it's not long enough to reach it. It also has a connector that looks like it would go on a temp. switch (in the manifold) - but that switch was replaced with a single wire to a gauge.
I've had other issues with the wiring the prior owner did but I've managed to fix all of those, this is my last wire issue.
