Up by the vacuum control valves behind the driver's side headlight I found a plunger switch just laying there. It's hooked up, but doesn't seem to do anything. Any ideas? I can't imagine it's supposed to just hanging there.

It's got a rubber boot on the switch plunger and the switch is about 2 inches long and maybe a half inch square. It's got 2 wires. Almost looks like a remote starter switch.

 

hood sensor for factory alarm.

 

Thanks. Seeing how badly the hood was adjusted when I got the car, I can take a pretty good guess as to why they unhooked it.
