Re: Help

By V6 do you mean inline 6? Battery connections good including grounds? Alternator charging at 14+ a bit volts? Chevy P/U wiring diagram is online but I don't know where you'd find one for a GM. One wouldn't think they'd be very different. Do they make the connections at the horn relay like on the Chev?
