I would like to thank everyone for their help with my tachometer installation. The only wire I have to hook up yet is the light wire. I had to splice into the ignition wire which was scary because I had never attempted that before. No sparks and no smoke so I guess it is fine.
I had to do this because I could not fit three ring terminals on the positive side of the Pertronix coil (Pertronix electronic igniton wire, ignition switch wire, and tach wire). The tach source wire (green) went to the negative side of the coil. I hooked up the tach ground (black) to the shock tower (securing it with those plastic things that hold wires and fasten to a hole in the shock tower. Sorry, I cannot explain it much better
).
Thanks again!
Justin
