Since this plug also controls the shift solenoids, you cannot just unplug it or the car will go into limp home mode which is 3rd gear.
I have a 1991 lumina euro. It just started the brake and stall thing - I found the plug it is 4 prong- first thing tomorrow I am going to unplug it and see what happens - will let you know what happened.
