It appears to be a coil.
A coil typically would have a + terminal, to which 12v hot wire comes and 2 negative terminals: for front and rear cylinder, to which correspondingly coded color[varies by manufacturers] wires come from the ignition module. Those 2 wires are intermittently grounded depending the cycle of the rotor in the ignition module- that's how the spark gets generated. Ignition on is not enough to produce continuity =ground/spark. It must sense the rotor rotation, when engine rotates...
The ignition module has it's own hot wire that is typically hocked to the hot post of the coil[ thus both get the 12v supply].
You can place any interruption you want on the hot wire that goes to the coil - toggle, key, etc and in any location.
My hot wire supply comes from IGN post of my 4post car ignition key-switch, so when it's on- the coil and ignition are both energized.
It's located by my
oil tank as I don't have anything on my handle bars. I can reach it and kill the ignition there just fine.
Some people prefer an additional kill switch by their thumb on the handlebars.
Too much wiring for my taste...
I hope I got your question right
