Kill switch help

[Ray74]

I should refrain from posting advice when wires are involved.----Very hard to explain simple concepts to some posters.

Electrical is not my strong point. Im far more a mechanical person.

Factory purple wire is listed as 12v wire according to factory color code.

Normally purple would be the positive power feed from the "A" terminal on the key switch. This should feed gauges, such as the tach, and any other thing that should be powered when the key switch is in the on position. All bets are off if someone has fooled with the wiring.
