i am a newbie here, but i will take a stab at this question. here it goes. if i remember correctly the 929 and protegee use whats called a resistor type door locking. in orhter words the DLM looks for diffrent values in the line. a single line. now depending on the the resistance of that line, that tells the DLM weather to lock or un-lock. but don't hold me to that. i could be wrong.

He's probably right.  Is this a one-wire system?  If so, it's probably just like a Chrysler.  You'll need to pulse a ground to the wire through resistors and relays.

Yes, I show two separate wires: lock(grey/black), unlock(blue/white).

I tested the wire again and its the same thing when you lock and unlock the wire.
im getting 12v.
now If I use a probe light Its a negative system so I would have to connect the red clip to 12v source then probe the lock wires.

Hey I don't want to thrash on you but it sounds like you don't know what you are doing. I would recommend taking it to a shop and have a professional look at what you are getting into. I wouldn't recommend installing alarms, remote starts, keyless entry systems unless you have the knowledge of car electronics. If this is your first you may try finding someone to help you that has done it many times before rather than a shop. It would save on time and money to find some professional help.

why are you talking thrash every car is different.
why would I take it to the shop when I can do it myself.
the other cars I worked on was cool but this one is a bit different.

You keep proving to us your wiring info, as well as mine is incorrect.  Try another wire.  You can start checking inside the kick panel, or you can back probe the switch and check for wire colors there.
