I have been out checking out my newly acquired 85' 380 and I am puzzled as to what something is. It is the thing below the alternator on the passenger side of the engine. It has two wires from it and it supposed to have a belt on it, but the belt is removed. Is this the air pump? At first, I thought it was the A/C compressor, but that appears to be the the lower driverside of the engine.

Thanks in advance!
