| LOCK | Pink/blue | On 16-pin brown plug inside driver's door | - | | | | These wires are found inside the driver's door on a 16-pin brown plug to the switch assembly (see the photo). If vehicle has no factory alarm, the doorlocks wires will be PINK for lock and BROWN for unlock. You will find them at the body ECU on the left side of the steering column. The WHITE/ BLUE disarm/unlock wire required a double pulse to unlock the doors, a single pulse disarms the alarm only. |

The BCM's next to the fuse box - which brings up an interesting question. How'd you do the alarm and NOT access/use the BCM? That's where you get the door trigger(s) and trunk trigger.
I guess you COULD run your own door/trunk pins, but what's the point??

it seems like you got the wrong wires...did you meter them?? I have done that car before and the wires are inside the door in harness coverd in tape running in the middle...there are colors that are almost the same so you must meter not just connect the wire and test...you can burn something out since you are giving an output...

You need to shorten the pulse going for the unlock and lock wires. Most alarms now have an option for a .2 second, 1 second and 3 second length pulse. You need to use the shortest setting. You will also need to turn on "double pulse unlock". It sounds like you have the right wires, you just need to change some settings.
In your last post you say it doesn't lock...then in the next sentence you say it locks but doesn't unlock. Explain...

Correction, my mistake. i meant to say when, i arm the alarm it does not lock. but it does unlock when i disarm it. now, i did find the wires at the BCM but werent functional. then i went on to the door and those where function BUT, the thing here was that when i armed the alarm the doors locked and the windows too.(that was strange). same thing when i disarmed it, doors unlock as well the windows rolled down and half way. again this was very strange. and now, well the driver side does not lock but it does lock with the alarm. i did everything possible to fix the problem but i ran out of resources. any help will be apreciated.

My installation program mentions that you may have a pink/blue wire and a WHITE/ blue wire at the bcm that arms and disarms the factory system but it rests at 5v and mentions to use relays to prevent a positive 12v signal. Your alarm may pulse positive or negative when triggered. One side will give 12v while the other gives a negative and vise versa. Try see if your lock wire gets any type of voltage when triggered by the switches of the key cylinder. Check with a multimeter for the proper results.
