Keyless remote installation on the 5000/100/200 cars

I did this installation about 2 years ago and worked great for a year then the
keyless
box died.  So I assume it was the box and not the installation.  I planned on
getting
another box but have never got around to it.

 I just installed a JC Witney Keyless remote in my 89 2000TQ.   Used the
wiring schematic from the 20v list  (shown below)  and it works great with the
alarm system.
 The wiring is pretty much the same  for  the 89 to 91 200's.

Wired and installed everything next to the glove compartment.

The JC Whitney system does not use the Lock NC and unlock NC wiring as
shown on the 20v diagram.

 1.The first thing I did was tape the two relays together and wired them
   up then I connected the remote box to it and powered it up.

 The wires that were not connected to anything were:

         a. line 3 - goes to anti-theft unit (Br/G wire)
         b. Line 8 - goes to anti-theft unit (Br/Y wire)
         c. Line from vacuum pump. (Bl/Y wire)
         d. line to vacuum pump from door lock. (Bl/Y wire)
         e. 12VDC (Using temp. to power unit)
         f. Ground (Using temp for ground)

 2. Used an ohm meter and hooked it up to c. & d.. When I pressed the
 remote button the ohmmeter showed that I was loosing continuity between c. and d.

 for a second which told me that it is was working correctly so far.

 3. I removed the glove box and footwell duct bracket that has the light and alarm
box on it.
     Found the wire coming from the right door lock (Bl/Y).  I then cut  that wire
and
    spliced in lines c. and d..  C. went to line coming from pump and d. to line
coming from
    door lock.

 4. Wired lines a. and b. to wires on anti-theft unit large connector.
 5. Wire lines e. and f. to wires on anti-theft unit small connector. This has
power and ground all the time.

 6. After I wired this all up I had about 3ft of line so I put the relays in back
of the
      radio and put the footwell duct bracket back in.  Put the remote box to the
right of the
       heater vent door and tie wrapped all the wires along the same bracket as
the vacuum lines are tied.

  7.  Pulled the right panel off the side of the windshield and strung the antenna
up on to the dash.
   I has about 7" of wire and strung it on the front of the dash down by the
windshield.  Install the
   panel, glove box and the side that goes to the right side of the radio.
   After connecting to battery back up it works like a champ.
