I would first ensure, that the yellow line from the wire harness is tied to a switched fuse in the fuse box, this would be why the compressor continued to run after you shut off your vehicle. The other thing you could check would be the air line connections that attach to the ECU (the black box) and then check the valves and see that they don't have any debris that could be possibly preventing them from closing.

Now if you ever do need any replacement parts there is the Replacement Wiring Harness # F2135829491, and firestone has a few we do not offer.
