I have decided to use a 3 wire on my 48 chevy 250, the alt was on the engine when i first bought it, so why change it. But i dont know how to wire it. I have looked at all the post on this and cant find my answer. Can someone draw me a simple diagram so i can get this hooked up. The only wire i know how to hook up is the hot wire from the alt to the starter solinoid.The other 2 wires plug in to the Alt which is a red and brown wire, these are the ones i dont know about. Thanks for any help.
