gm94,
Did you ever reconnect the alarm?
I just went through installing an alarm on my 93 MGM and got the info from Alarmtek after reading your post. They told me that the car had reverse polarity so I followed their directions. Did not work.
I checked the door lock switch and it is 3 wire negative system, not reverse polarity.
All I had to do was splice the lock negative output from alarm to the pink/yellow wire and unlock negative output to the pink/light green wire.
