2007 acura mdx door locks

It appears that they have changed locking systems for 2007. Does anyone have any experience interfacing with these cars? Its not a standard negaitve trigger anymore, and it requires the breaking of one of the wires at the key switch to lock properly. It is a double pulse unlock, but there are two wires that must be pulsed at the same time. A diagram would be great.

Thanx guys.

Take the drivers door off and test the wires at the key cylinder the will read (-) when turning the key in the door these will also control the factory security so u will need to unlock before start lock after. The molex plug and the boot are fairly easy to run your wires through. hope this helps you

I wish it was that easy.

There are 7 wires at the lock cylinder. 1 is a ground, 1 goes to ground with unlock, one goes to ground with lock, 1 goes to ground with lock, and the other 2 go to open or ground depending on the position of the lock switch.The 2 that go to ground when you lock or unlock with the key do nothing when pulsed by them selves. What I have done so far is as follows:

For lock, breaking the wire that goes to ground when the switch is in the locked position, and pulsing the side that goes to the door module at the same time as I pulse the wire that goes to ground while locking the door with the key will get it to lock consistanly.

For unlock, pulsing the wire that goes to ground when you unlock with the key at the same time as I pulse the one that stays at ground when the lock switch is in the unlocked position wil unlock the car about 50% of the time when my unit is programmed to do a double pulse unlock.

I did this install on Saturday, and the customer left with the knowledge that he may have to press the unlock button twice to unlock the doors. He hasn't had any problems yet, but I had it fail a number of times in the bay. He brought the car back today so that I can dig into it deeper, but I haven't gotten it to fail yet, and that kind of ties my hands with regard to troubleshooting. He is really cool, but I am losing sleep over this. I can't stand having a car out in the field that may or may not operate correctly, especially if I can't identify the problem. Any other ideas?

Try switching from .750 sec pulse duration to .125 ---> doesn't holding down the unlock button start the window/sunroof roll-down feature?  I recently did a Nissan that needed the pulse duration to be switched down to 0.125 sec and then double pulsed for unlock in order to prevent the roll-down feature from initiating w/ a simple unlock from the keyfob.
