Technical gurus please help, I have a 1967 camaro (base) that I have added a NOS tachometer to. I looked through my factory assembly manual's wireing diagram to see how to wire in the tach...nothing there in diagram showing it. I do not have the console or gage pod. The "bulk-head" wiring connection that plugs into the plastic like circut board of the speedometer/tachometer is where I am assuming the needed wires will have to be added, and then run to the coil???
