I'm tiring to figure out how to wire this thing up. My wiring diagram shows orange & purple wire goes to "positive terminal on coil" (picture 2) . Do I splice those wires into the red wire coming out of pigtail (picture 1) . Gray wire from my tach says "negative side of coil/point terminal on distributor" would I splice that gray wire into the "c -" wiring coming out of distributor (picture 3) . Or if anyone is close to Fullerton and want to show this rookie first hand . I supply lunch and beer!
