datzenmike Posted May 22, 2010 Report Share Posted May 22, 2010 Bill there were two style of 620 tachs. The one below is the inductive type I think, the one below may be the pulse type. Sorry I can't help more but perhaps someone can chime in on this. I think 4 and 5 is spliced in line between dizzy and the coil neg terminal. The tach senses the signal in the loop of wire. If it has a single wire (like below) it can be connected to the Blue wire from the neg side of coil. . Quote Link to comment
