Hi, in a box of parts I found this, I just bought a 69 SS Camaro and thought it was a speedo warning,but the car does not have one. Its about 2 x 2 x1 with a **** that turns, a small light above the **** and one wire..thanks

 

Flux-capacitor...?

 

Could you make the picture a little smaller? Maybe that will help.

 

 

Thanks, I found out it is NOT a GM piece, it's a sensor for an old style alarm system
