Re: [DMCForum] Re: ANSWERS TO MY SEVERAL ELECTRICAL QUESTIONS

Bill,

You're awesome, right on the money about the question
of the day.  The black and light green/white wires
were for the little light on the shifter lever of the
automatic.  The clock has a 4-wire circular connector
that goes to it.  Does #5939 have a console clock in
it??
