I'm trying to hook up dual Plasma III systems to my AFS 3500 which formally had a Slick mag pickup with three wires (as detailed on the wiring diagram of the installation manual. Light Speed says that the RPM signal is on pins 6 and 13. But how do you connect two wires to three?
Shawn McGinnis pointed me to page 188 of manual v3.0 which is the same as above and doesn't help me. Also offered was the purchase of a 71420L, but I can't find any information on pricing or description on the web site.
Help appreciated!!
