heh, heh.... don't need power-resistor as it's just high-impedance sensing-line. Regular 1/4-watt resistor will do. ECU actually gets full 12v operating power from brn/blk coming from IGN fuse (same as coils).
Are you going to away with right-hand electronics? Just push-button for starter? I replaced both my right-hand controls and ign-switch with one of these. Although mounted on left, to make it easier to operate throttle while starting.
I actually removed 2 unneeded wires from this as it also had output wires for IGN OFF and START OFF positions. Not sure why....
