    This electrical plug is the pass-thru electrical harness.

    it's a 20 wire connector and is part of the transmission harness, once it goes in to the trans. it divides to multiple sensor connectors.

    the O ring at the pass-thru is leaking. I don't know if you can purchase just the O ring. If not, you have to replace the harness.

    The trans. pan has to come down to remove the pass-thru plug. (not too hard of a job )
