fyi you dont have to leave the key in the on position for the 10 min time out. You can go get a nice dr. p or something while waiting for it to time in.
Definitely just replace the switch. Although I was considering installing a passlock bypass (I can get em cheap through work) and putting a switch on the bypass. Then I would only kill the system when the ignition timed out...but who knows how long till the switch fails altogether.
But...if you're really set on bypassing the system, I can pull the bypass wiring diagram tomorrow at work and post it for you. All it takes is a resistor
