I think he is talking about an ignition priming switch.. or battery kill.. or whatever.


If he is talking about a start button , then thats a pretty silly idea with no practical sense at all, and absolutely not a theft deterrant.

If it is a battery out circuit style switcher type your talking about then its way easy, there are several wires you can use.. including clutch wire, ignition, 12v battery, amongst others.


Search is your friend for that matter.
