Little white switch on the ignition switch

[dwragon]

Anyone know what the little two wire white switch on the top of ignition switch does (multiple years 94 to 2002 that I know of)? Was changing out a switch when the white switch plastic crumbled. I think it has something to do with security, and can it be bypassed?

There wasn't an antitheft feature on GMT400's until 1998 brought Passlock onto the scene and that's a black plug with several wires coming off the steering column casting just above the ignition switch tumbler.

1994 and 1995-up are very different columns, but I suspect on 1995-up (your truck is a 1997 correct?) you may be looking at the key-in-ignition switch which would operate the chime so you don't forget the key? 1994-older has that feature too but it's a small chunk of plastic inside the column with a couple contacts coming off it.

Ahh, ok, so if it has nothing to do with security, (being the key-in-ignition switch which would operate the chime) a person could just snip the wires and ignore it. I will try that and post the results. I so much miss my old 64 C10 death trap, it was so simpler....
