Hey. On my 86 camaro w/2.8, my alternator died. I got a new one for free for an 87-92. I know that I have to swap pulleys, and adapt the new, smaller alt to my existing bracket.

My question is this: My current alt is a two wire set up for the plug. This one I have now is a 4 wire. My thinking is to get the 4 wire plug from the scrap yard and adapt it to my 2 wire system. Which two terminals on the 4 wire alt do I use?

Thanks
Rick
