I'm installing an alarm on my '89 Honda Civic hatch and would like to use a magnetic switch on the main relay. I've read about other people using the DEI 8600 but I think it is Normally Closed and if I understand correctly, I need a Normaly Open switch.
Basically, what I want to do is what I read on another site but which did not provide details:
This installer hid a 'magnetic' switch on the (-) fuel pump line under the carpet. When he leaves the car, he simply lifts a magnet off the carpet and the fuel pump gets killed. When he gets into the car, he places the magnet in a "sweet spot" on the carpet which closes the switch and re-activates the (-) fuel pump line. He does this automatically and 'secretly' and not even his passengers know what he is doing - better than a hidden switch which your passenger might notice you activating!
I want to emulate this on my car but with the (-) main relay ground which kills the ECU, injectors, fuel pump and a couple of other sensors. Any suggestions as to the type of switch I need and where I can buy it? Since I'm disconnecting a low amp ground, the switch does not have to be high capacity.
It has been many years since I have used one of these, you will need to check and make sure that they still have a Normally closed and a normally open connection.

Ah all that old school stuff, Craig do you remember the the pressure pads? Just out of interest I personally wouldn't want to kill the ECU let alone those other circuits.

Thanks for the link but that switch is normally closed with the contacts apart - the opposite of what I need.

Please explain. Killing the main relay is a common 'trick' on Hondas and Acuras but is usually done via the alarm. I currently have it on a switch but was intrigued by the 'stealth' of the magnetic switch.
u can do it,just be careful since u are relying on the magnet make sure its secure u dont want the engine to die on u while driving!

They do make similar alarm switches that are Single pole double throw.

el ranchero has explained what was worrying me. go round a corner quickly and lose the magnet, lose your car. I know our Cat l alarms call for two cuts but I prefer just to cut the starter wire, it's much safer.

Good point - thanks for the heads up!
