What is the secret to these? I want to take a 3g alternator, and make it one wire for a old mustang. I see them on ebay for 160 dollars, and could make my own for 20. at least I hope, would it not just be a matter of getting the diode to activate?

I don't know the secret but I know they don't use the wiring harness, just one wire to the battery.I wish I had known about this because I had to junk an old pick up back in the 80's because no one could fix the voltage regulator problem.

No secret. The voltage regulator is built-in. Once the alt spins up to a certain speed(usualy around 1,000 engine RPMs) it turns on the alternator and the regulator kicks in and regulates voltage like on any other type of setup. Once the RPMs drop down to 0 it switches off again.

interesting. I found a couple links, and think I'll just wire up the 3g myself. According to this: 3g wire up I only need to wire switched ignition to one of the wires on the plug, and steady +12 on another. The +12 can just be jumpered to the output post, so in theory I'll have a 2 wire alternator, for 25 bucks.
