youre talking about a one-wire, right? I believe you just run a wire to the starter solenoid and make sure it grounds out to the block and GO. I wished i'd done this for myself since i put a new regulator, alternator, and harness in and still have stock output.

You can run it to the battery post or the solenoid . . . same basic difference. I don't remember for sure now what it was but there was some re-wiring I had to do to the harness that runs through the regulator. Otherwise the truck wouldn't start. But it only took me about an hour to dig through the mess of wiring and figure it out . . . was pretty simple.

bc broncos has a very easy to follow wiring diagram on how to wire in a 3g alternator in any engine you can fit the 3g case into.
I got one in my 78 bronco. It took about 30 minutes to swap in including removing the old one and doing all the wiring.
Just be sure you fuse the charging output on the 3g. 130 amps is enough to catch on fire real fast.
