Hello List!!

Let me begin by saying I hope you all have a Very Merry Christmas, and a great
New Year!!  Also thanks for all your help on my projects over the years!  With
the holidays approaching, and a few days off work I am planning to upgrade my
tired TH350 with a 700r4.  the tranny is almost ready to be installed, but I
am trying to understand how to wire it up so I have a 4th gear lockup and
release when I decelerate or hit the brakes.  I have read a number of posts on
the subject, but most involve later model trucks.  There is a 4 wire plug on
the driver side of the tranny that has three wires coming from it.  I was told
to wire the "A" position on the plug to the a keyed hot wire, and to wire the
other two together.  I am confused how to wire the hot wire to my brake switch
and still have it hot until I hit the brakes (to release the lockup). It was
also suggested that I include some sort of solenoid in he circuit to delay the
lock/unlock to make for smoother operation.  Could really use some help in
sorting this out.  Pictures would be great, or just a description of how it is
wired up.

Thanks in advance for your help!!

Mike
