Instructions to wire msd box kill on page 6: http://www.msdignition.com/pdf/6series.pdf

I'm trying to figure out how to wire it using a momentary switch. The theft detterent on the MSD box only cuts spark when the white wire is grounded. A switch has to be activated in order to start in my diagram. The thing is it has to use a toggle switch. The white wire must stay unground in order for the car to have spark. I'm guessing I'm supposed to use another relay to get it to work, but how would I wire it so. Also, If I were to wire it to a a parking switch or any accessory as a switch, how would I wire it? The diagrams on the site are normally open configuration.

Also, what's the radio accessory wire on a 94 Honda Prelude. Is it the switch 12volts yel/red wire?

Ok what it sounds like you want to do is wire a switch that will prevent the ign from getting spark to be used as an ignition kill security device(hitting the switch will keep the vehicle from being started not just killing the engine). This cannot be done with a momentary switch alone. The easiest way would be to use a toggle switch(1) and a relay(1). If you are dead set on using a single momentary switch then you will need to use this Diagram. You will also need to wire another relay converting the output to ground.
