I have a question about hooking up my remote starter to maintain the progressive door unlock - my OEM fob and vehicle settings allow that a single push of the unlock button unlocks the driver door, and then a second push unlocks all doors. I'd like to maintain this for security reasons for my wife so only her door unlocks.

I have a 2007 Jeep Liberty. The remote start unit is a DEI 562T.

I have tapped into the lock/unlock (single wire system) and will be using relays with the correct resistors. I've tested by just grounding the wire with the two sets of the resistors and all the door locks lock and unlock properly.

So, I have two questions:

1) Where can I hook to just to ensure the driver's door unlocks? I assume right on the actuator in the door?

2) Please confirm for me - the blue wire on the door lock harness should go to my UNLOCK relay setup, which should then connect to the answer of question #1. The green wire on the door lock harness should connect to my LOCK relay setup, which will go to the single lock/unlock wire. The blue wire on the H1 harness (labeled "-" Second lock output) can go directly to the single lock/unlock wire as it is always a "-" output. Am I correct?

Thanks in advance for your help!

Drivers door unlock is tan/lt.blue @ the junction box in a green plug under the dash! Wire it for reverse polarity and trigger with first unlock. Do the rest of the doors unlock on the wire you are using with the correct resistors. and second unlock.

Thanks for the reply...I am still having a little trouble.

I, cannot, for the life of me find a green connector under the dash. Are you talking right off the body control module? I found the upper left connection there. I found two tan/dk blue smaller gauge wires off that, and both seem to trigger all door locks. I also found a heavier gauge tan/dk blue and a heavier gauge tan/lt blue, but these won't seem to trigger anything. Should there be a small gauge tan/lt blue in there, or is it somewhere else?

Thanks!

Anyone? Can anyone direct me to this wire/connector?

Can anyone identify the rear defrost wire color/location (out of BCM?) on a 2007 Jeep Liberty?

Also, please confirm that I am correct in the relay wiring:

85 - "+"12V Constant
86 - "-" 200ma Input from remote starter (DEI 562T)
87 - High Current "+" 12V
30 - Vehicle Defrost Wire

*** And, it's OK for 85 and 87 to be from the same source, correct, as long as 87 is high current? I plan to run heavy wire to 87, then jumper over to 85 with smaller wire.

Thanks!!!!!

BCM connector #1 light blue wire pin #23

requires a negative pulse.

If you don't know what wire ..... you could NOT know how to wire the relay. re-think you relay setup!

p.s. you shouldn't need one!

Thank you for the reply. I am totally lost here now. The information that I was going off of was from THIS post from a while back - please see the 1st reply, #2.

I'd truly appreciate it if you could point me in the right direction. I have everything set to go on this except for the rear defroster and the rear window release. If you don't mind, can you please instruct me on each of these - defrost and release on rear window?

Thank you.
