Sun Super Tach

[jhill52]

I have a Sun Super Tach II from in the 70s that I want to hook up in my Bronco. Some where over the years I lost the wire harness and connector. Does anyone know where I could get a connector or an entire harness?

I went on line and found the wiring diagram.
Mine only worked for a few weeks. But like yours it was 20+ years old.

Does it have the common 4 wires that most aftermarket tachs have?
Red, power
White, light
Black, ground
Green, negative side of coil (or tach output with CD box)
