  • Jon,
    Bingo!  The alarm is silenced, but all the door and other locks still
    function the way they should, including the automatic closing for the
    windows and sun roof.  Thank you for the guidance.  I must admit You had
    me with the "Becker box", which with my limited mechanical ability could
    just as well have been a "hyperbolating renostat.  Since there was only
    one box with plugs on the side, I held my breath and went for it.  Best
    always.
    Greg
