Mopar Dealer Tachometer

I recently purchased a Mopar Dealer Tachometer in excellent
condition. I want to install it on my Dart but I received it without
any wiring instructions. It has three wires coming out of it. A red
wire, a black wire, and a white or possibly white with green stripe
(wire is faded). Does anyone know the correct hook up since I
don't want to risk damaging it.
