You should have a pink, violet/black & a blue/orange wire.

The Pink wire goes to the - neg side of coil for Tacho sender
Violet/black to + side of coil if not using a ballast resitor. If using ballast resistor connect to one side of resistor then take another wire from other end of resistor to + side of coil.

Blue orange goes also to + side of coil but not connected to resistor and only if you are using a ballast resisitor, it acts as a bypass if resistor is employed for cranking. If you are not using a resistor then do not connect it at all at the starter or the coil.

Hope this helps.
