Don't know about diesels, but on gasoline engines the camshaft sensor (Hall sensor) is usually on the side of the distributor. On mine it's a yellow&green wire. I tapped into this wire at the firewall and brought 2 wires into the cockpit and attached them to a momentary open button. This works great because the ECU thinks the engine is stopped and stops both the injectors and the spark plugs.

BUT *CAREFUL*! Interrupting this Hall sensor may cause your ECU to "throw a code", such as "No signal from Hall sensor" (what else?). In my car this constant writing of error codes caused the ECU to sometimes forget the ignition key authorization code, thus activating the electronic anti-theft immobilizer and the engine refused to start. At least that's my theory of what happened. Then it's time to tow to the authorized dealer.

Here's my thread of my experiences: http://ecomodder.com/forum/showthrea...ers-11153.html
