After much research i understood that you need to set up two relays (like in the reverse polarity door lock relay diagram)for both the passenger side door and the driver side door to lock and unlock doors ( passenger side suppose to unlock all passenger doors) i wired them all up but only the driver door and the front passenger side door is unlocking and locking with the alarm i made sure every thing is right i dont know where i went wrong any suggestions?

or you can get a module that will tie into the data wires or the ODBII and work them with data. 1996 - 1998 JEEP DATA BUS DOOR LOCK & ALARM CONTROL INTERFACE (455TW) DEI The xk03 will work on 1999 and up and do the locks and OEM alarm.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

I wired the relays in both front passenger door and the driver side door exactly the way in the diagram and it still only locks and unlocks the front

I tried everything i still cant get the rear doors to unlock and lock with alarm........i forgot to mention that its a right hand drive version i try lookin for the module to interface with the keyless entry with little luck...i live in the caribbean so prolly i would have to order it on the net and get it ship here.

I'm not going to say positively since I've never done locks on a JGC of that type, but if you're brave you may be able to take apart the door module, figure out where the PCB traces or wires go to the actual lock switch and connect to them...however I wouldn't recommend that unless you're very good at figuring out a PC board by sight.
