Chrysler Repair: 90 Imperial wont start: how to remove security system?, straight pins, electric locks

Question
is there a way that the security system can be totaly disabled bypassed so it functions like a reguler car  

Answer
Hi Mark,
If you don't use the electric locks to secure the doors, and instead use the pushbuttons only then the alarm will not be set. If you want to get rid of the alarm system entirely, that can be done. But first you have to disarm it so that you can start the car. Here is how:
First is the question of where the system is located:
The manual descriptive section shows it to be located above the glove box opening (remove screws around the glove box door opening, remove under dash pad so you can drop the box out of the way; look for a metal structural element running crosswise above the glove box opening and see if there is a rectangular module with a 21-pin natural color plug on top of it. If so, that is the theft module. This is important: do not pull the plug out of the module UNLESS you have disarmed it or it will treat you like a thief and really lock it down. The engine has to be RUNNING when you pull the plug out of the module!
To get the alarm disarmed notice that there is a row of 11 and a row of 10 wires in the plug. Look at the 10 wire row and count in from the end that doesn't have a tab to the fourth wire, which should be dark green/orange; and also locate the black/light green that is the first one on the same end of the 11 wire row. Take two straight pins and probe straight thru the insulation of each of those wires so as to contact the conductor in the center of each wire. Then touch the two pins together, then separate them from one another. This is simulating the lock/unlock of the door key cylinder. That should disarm the module and you should be able to start the engine. Only when the engine is RUNNING is it safe to pull the plug from the module, and it will not work again and the car will no longer have a security system.
Reassemble the glove box, put the underdash pad back, and you are done.
Write me if you can't identify the wires in question. Of course, if you can disarm it with the door key lock and get the engine running, then you don't have to do the straight pin simulation of unlocking the door. But I assume that you haven't been able to disarm it, so you have to fake it out.
