Vaccum hose for door locks: Where is it

[Pat Korach]

I installed a wireless remote door opener on my 89 200TQ which worked with
the alarm system.  It was connected into the wiring behind the glove
compartment
which was part of the right front door harness..
I ran the antenna wire up the side of the dash and the system worked like a
champ.
The original diagram I got for doing this was off of the 20V list and I
adapted it to
the 89 200.   If you would like a copy of it and how I dit it I could E-mail
it to you.
