I did the same thing on a 82 camaro. I did this.
The 1 wire plug on the alt I made it key on hot, the lug on the back runs to the battery. It worked like a charm and have had no problems.

its probably a cs style alternator. if you can post a pic of the connector or describe it, they are pretty easy towire up. probably a 4 wire connector plus "BAT" terminal.

There are two different wires that are generally needed for a CS130 to charge.

one is the "L" terminal for the warning light. this _MUST_ be used. all it needs to be is an ignition switched 12v source, run through a small 194 type light bulb and to the L terminal if you don't have some factory setup for an alternator light.

the other wire is a sense wire. simply connect it to the big stud on the back of the alternator. (There are better ways, this is just the easiest)

this is basically how I wired up a CS130 into my 1972 monte carlo, and it works _GREAT_

that 20A fuse is a little big.. should probably use something more along the lines of 5A
