Actually, TB, if I'm not mistaken, the tach wire and signal wire (to the module) are in effect the same terminal, no? IN other words, electrically, the coil only has 2 primary terminals, + the coil hi v. wire.
Yes, that should be correct.
One 12+ (ign), one ground (one of the wires on the module), two wires for the pickup signal and a tach lead.
But which is which is the question, and I can't find a diagram anywhere for some reason.
Only a description that I posted.
