Hi all

I am planning on installing an engine kill / engine start button arrangement on my 2003 C220 CDI Manual.

The engine start button is easy, just wire it into the starter relay.

The engine kill button is a bit more difficult. I am planning on using a normally closed switch into one of the wires on the CAM position sensor.

If I unplug the cam sensor, the engine stops, but I have to cycle the key for the engine to start again.

any ideas which wire I can tap into to simulate a 0 RPM signal?
