    Is there a part number marked on the device? If you can porvide a part number then we may be able to locate a datasheet.

    Try tracing out the circuit board that you removed them from.

    One lead is going to go to ground, and one to +V. A third lead will be the output signal. Hard to say what the 4th lead will be; it may be that ground or +V is on two of the leads.
