I'm making great progress on a rebuild of my 1986 Merc. 4.3L V-6 that someone else took apart for me. Had to replace the starter & on the new starter there are 3 poles for the wires. The main is for the 3 hot leads & then I have only one wire left. I recall that on the old starter that wire was on the block side of the starter (looking down from the top) but I don't recall if it had that extra post. I can't tell from the picture in my manual which lead that wire goes on. Can anyone confirm which post to put that last wire onto?
