Default Mystery switch under dash...left side

Last night I was removing some wiring from an alarm the previous owner had in my '70. The alarm hasn't worked since I bought the car and I feel it may be helping drain my battery.

I followed one wire through the engine compartment, fire wall and to a switch under the dash. This switch is to the left of the steering wheel. It is next to some other switches...there are 2 plastic switches which I believe (?) are vacuum switches...then there is a switch that just has a knurled end on it - looks like it's meant to be turns, not "flipped" if U know what i mean...what is this for?

But the big question is...this wire I was tracing went to a simple 2 position toggle switch which was mounted by the 3 above mentioned switches. This switch also had another wire connected to it, but I don't know where it goes. Does anyone know what this is for? It looks VERY hard to believe it's a switch that Chevy put in with the car...probably something this guy did. Any help? I don't know if I should remove the switch and wire or what to do...any thoughts would be very appreciated!

Could be cutt off switches for ignition, fuel, fan motor or alram. My guess is passenger side ejector seat or oil slick/smoke screen switch. Could be warp drive enable....

Nah, that's the cloaking device enable switch.

Seriously, it has to be add-on, and I'd guess kill switch.

Does the knurled switch look anything like your trip meter re set or your head light over ride? I'm trying to get an idea of what your looking at. :confused:

That's my guess if it has knurling on it. Try pushing it in instead of rotating it.

Not sure what the switch is for that has the wire going to it but the one that is meant to be turned resets your trip odometer.

The 3 "original" switches under the steering column are the vacuum over-ride for the headlights and the vacuum over-ride for the wiper door. They work by pulling them down. You can open either the headlights (without turning on the lights) or open the wiper door (without turning the wipers on). The **** in the center is the wiper "service" off/on switch. When your wipers are going back and forth, if you turn this switch, it shuts the wiper motor off allowing you to work on the blades, replace the refills, etc. The fourth switch is an add-on. My guess is that it's a cut out switch. I'll bet it breaks the negative coil wire, so the car won't start without the switch being turned "ON". That's the "old time" original safety device used decades ago. PS: You should buy an owners manual and an assembly manual. The assembly manual has both vacuum and wiring diagrams. Chuck
