Any folks with Magneto experience?

[TX3100Guy]

I have had a Vertex magneto rebuilt and cleaned. I've now installed it and a new wiring harness, complete with a kill switch for the mag, (Joe Hunt did the rebuild). I also purchased from them the Magneto Tach Converter, since I'll be running a newer electronic tach.

Has anyone used this box from Hunt for this purpose?

I have downloaded the wiring diagram that comes with the converter and I'm still a bit confused. Here is what I think needs to be done.....

Red - connect to a 12 volt switch power source
Black - connect to vehicle ground
Violet - connect to the input of the tach
Brown/Black - connect to one side of the kill switch along with a wire to the vehicle ground
Brown/Orange - connect to one side of the kill switch along with a wire from the terminal on the magneto
Brown/Yellow - No need to use in my situation

Does my interpretation of where the last three wires go correct?
