Kill switch

[FastWoman]

Steve and 5th, that's not bad at all! I generally bristle at these sorts of discussions, because by engaging in them, we're only telling thieves how to steal our cars. However, this is one solution a thief can know about and still not have a clue how to defeat, unless he knows exactly where the defeat device is hidden. Very nice!

My girlfriend knows where and how and still doesn't understand how to do it all the time.

I was going to post a new question about kill switches, but since the conversation has started...

Do I need a relay?  Can I just splice a metal toggle switch or rocker switch in the wire I wish to disable?   ( I know this would "work", but I would prefer to avoid any fire/electrical problems)

I was thinking about either the ignition wire, the fuel pump (electric) wire, or the starter solenoid wire.

Electronic relay that goes to solenoid for starter / fuel pump (i hear that some people bring their own fuel pump {seems like a pain in the butt}) relay is hooked up to a arduino micro controller which has a bluetooth fob on it, requires authentication from your phone bluetooth, or a bluetooth fob keychain. 

Its been in the pipeline for like 3-4 years, my buddy wants one in his CRX and Miata. Maybe once i get this car sorted out ill be able work on it... (>.>)
