If you have a schematic or can find the "coil pickup wire" from your distributor (if you have one - I don't know your engine), that's the wire I spliced into. (I'm the person whose post you read, I think.)

It's not a high voltage wire, it's just a signal wire from the distributor to tell the coil the position of the rotor. Interrupt that signal and the coil stops firing. No engine codes are thrown, and the ECU/gauges stay live.

My kill switch is on the shifter also.

EDIT: on the Suzuki motor, there are only two small wires coming off the distrubutor. They're the wires for the pickup circuit. I don't think it matters which one is spliced into the switch circuit.
