I am using this and somehow have misplaced the wiring diagram.It's reading too high-so need some help.The lower 4 terminals are from the left-- ( + HI LO -- ) There are 5 small white switches in the middle(marked 12345) with (OPEN) written above them.Tacho part no. is 333-354.I have just about worn Google out trying to find one,but no go.Would be grateful if somebody had a wiring diagram for a 4 cylinder.
