good thread...where does the tach wire into the diagram? thanks, CC
Looks like you'll have to call MSD on that one. I've looked in my book and it does not show any place to wire in a tach. Usually they will have a grey wire coming from the box harness that is the sense wire for the tach, but the book does not show it.
Should plug right into a single male spade terminal recessed into the side of the box.
I did just what your doing. There is a connector kit from MSD to change the plug on the box ot the water tight one. You just snip the wires and crimp on a new one. If you can't get one where you got the dist you can order one from Rex Marine. They new exactly what I need when I ordered my distributor.
