At work now, was able to pull up tech diagrams for the vehicle. the switch is NC. so putting the clutch in completes the circuit. bypassing it should allow the car to start, disconnecting the wire wont do anything.

testing/inspection procedure for the vehicle is two lines.

1. Disconnect clutch start switch electrical connector.
2. Use a fused jumper wire to bypass switch by connecting terminal A to terminal B. Switch is faulty if engine cranks normally.

If that is your problem, you could actually just do away with the switch all together by making a loop of the wires. if you do that just make sure that the vehicle is never in gear while starting, or you could have some issues.
