I have a GM 'connect and cruise' package in my 70ss and the harness has a wire marked to go to the alternator. I also have the VA one belt system that has a 4 wire TuffStuff alternator. I am running it with the GM supplied feed,

Problem is that it only that the computer only supplies 4v at idle. I have to go past idle to keep lights etc from dimming. I am going to change back to original 'brown' wire method after I confirm its OK with TuffStuff.
