Adapter for HEI Ignition with Aftermarket Tach?
I'm new to this forum so immediately I apologize if there is a thread already on this that I wasn't able to find. I'm in the process of restoring a 1970 442 W30, and I'm not exactly sure what I need to do with the Tach. I purchased the aftermarket Rally Pac gauge set from The Parts Place, and the guy on the phone said I might need an adapter for the Tic Toch Tach since I have a Pertronix HEI ignition (see ignition pics below - this came with the car when I purchased it). That said, I haven't been able to find this "adapter" for sale, or that I even need one.
Is there any reason this won't work with (1) the 1.5 amp fused wire from the right post of the tach connected to the negative side of the coil (2) the orange wire for the clock feed and (3) the grey wire for the lights? Any help is greatly appreciated!
