[DML] Re: Door locking system question

["Harold McElraft" <hmcelraft@xxxxxxx>]

Everything works from the lock module. At the module I tapped my 
alarm into the lock/unlock wires coming from the door switches. NK 
and NS colored wires. See M:18:14 of the Workshop Manual - the 
grounding symbol on switches 3 and 4 is missing on the switch lever 
but they appear in the main wiring diagram. They are grounded by the 
door switches to activate the door locks - one for lock, one for 
unlock - I don't remember which - you'll have to test. This works 
both locks at once. If you want to activate the door locks 
separately then you will have to go into the door lock module or 
directly to the door lock solenoids. Something I would not recommend.

If your alarm is similar to mine then the alarm, upon activation, 
provides a ground or a positive current to activate the door locks. 
You would want to use the wires that provide a ground for both lock 
and unlock modes. You may want to put a diode in the line to 
eliminate any feedback to the alarm when activating the door locks 
normally or an extra relay to provide a complete break in the 
circuit to the alarm. Since I was uncertain of currents required of 
the older technology of the door lock module I used separate relays 
for the alarm interface so the ground was a direct ground when the 
relay was activated by my alarm module and the alarm is completely 
isolated from the circuit during normal operation (probably overkill 
but I could also then use either alarm logic and I didn't have to 
worry about feedback).
