95 jeep grand cherokee lock system

i have a 95 grand cherokee 4.0 and i would like to know what type of lock system weather its central or reverse polarity etc.  Because on my alarm the doors will lock but they will not unlock with the remote. Beep Beep who got the keys to the Jeep

It uses a positive trigger relay driven system.

i dont understand what you are saying. can you draw a picture of how you have things hooked up?

its a phonics digital alarm pd-175 for the locks its 2 wires for each lock i dont have the diagram in front of me but i beleive its for door lock it white wire to trigger and yellow to 12v and for unlock its WHITE/ black to trigger and yellow/black to 12v thats how i have it wired the lock works fine i tapped into the trigger behind the door panel in the lock swith i did the same with unlock but it didnt work now i have the unlock tapped into the trigger in the passenger kick panel like it says in the tech sheet but still nothingBeep Beep who got the keys to the Jeep

Yep, that how you would test it. i would test it just to be sure its the right wire you are trying to interface with.

thank you for ur help i will check next time i can i appreciate it very muchBeep Beep who got the keys to the Jeep

the jeep cherokee uses a very strange door lock setup. im gonna look some stuff up but i know the last one i did required 2 DLS relay packs. so 4 relays in total. i believe it is a dual reversal rest at ground. ill post back soon. I just remember the last one i did used alot of relays. lol
