Chrysler Repair: 93 Chysler Lebaron - Alarm system, straight pins, descriptive section

Question
I cannot turn off the alarm system.  how do I disconnect it.  The key will not deactivate the alarm as the manual describes.  I bought the car used about 3 years ago.  Disconnecting the battery only reactivates the alarm as if it has been tampered with.  I would like to disconnect it completely since I do not use it.  We always lock it manually to keep from activating the alarm. We were cleaning the car last evening and the electronic lock was set which set the alarm.

Hi Jennifer,
O.k. it is fortunate that you have a separate theft module rather than one that is part of the body computer which would make things more difficult. First is the question of where it is located:
the manual descriptive section shows it to be located above the glove box opening (remove screws around the 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 put 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 pin row and count in from the end that doesn't have a tab (or start at either end and observe wire color on #4 and #5 wires which should be dark green/orange and black/light green when you have started counting from the correct end, or notice that there is no wire in the #10 pin wire socket and so start counting from the other end).
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. Then when the engine is running pull the plug out of the module and it will not work again.
Reassemble the glove box and you are done.
