Anyone know what wire of a reg 4.3L distributer is the Tac lead. The hanes manual doesnt say and want to be able to hook up a tac. there are 2 harnesses that i can see. 1 with 4 wires and 1 with 2.

Thanks

One that comes from the coil that doesn't have 12V with key on, engine off. Or the one that flashes with a test light while cranking, don't think Chevy put negative on their coils anymore, but that's the one you want.

I ended up calling GM and found out where to hook up the lead. the white wire between coil and distributer. It works like a charm
