Re: how is door sensor wired up as red and black wires...
I think you could
use this manual method instead.. My nephew who is a full time mechanic uses most of the times, and all mechanics look up to manuals. It's very easy Here's the website he bought it from. www.reliable-store.com
i repaired my wifes car same fault.you need to remove the lock catch mechanism out of door(not door lock) it's tricky belive me 1st time.check how this is done or you could destroy window winder.glass .needs to come out ect.on the side of lock a micro switch operates lamp and buzzer. i cut it off and glued it tighter to lever works fine now.
Try "clearing the cache" by removing the negative battery cable for a few minutes. Before doing so, be sure you know how to reset the clock and radio codes & presets.

Look underniethe dash for a rectangular black box, older chevs had the chime separate to the radio, yours may be old enough that it still has the chime box. If not, it could be the connection at the door or a bad door latch switch, via a wiring diagram you can find which wire diactivates the chime and either splice it or disconnect it, the system could work with continuity or an open circuit.
The locks are tied into the alarm control unit. The control unit has a
starter lock out. If the alarm system did not see a door open using a
key, it does not deactivate the starter lock out.
Normally if you have a
bad door contact switch you can open another door or trunk to test this
theory out. Since you can not do this, we will need to take a few
steps. You need to locate the alarm control unit, it is a small black
box located just to the left side of the steering colum. You will see a
large conector of wires that go to it. Locate the two large red wires,
one will be red and one will be red with a black stripe.
Probe both
wires, and while turning the key to the crank position you should have
power going through both of these wires. If not let me know. If you do
have power going through both of the wires, then the problem is not the
alarm unit.
This sounds like a starter disable feature of a car alarm. Somewhere under the dash you are going to find a box with the start wires running to it. The start wire is black with a white stripe and is thick, about a 12 gauge wire. It will come from the ignition switch and run into a relay or box. It could be installed anywhere as it is aftermarket. Once you find it, you can reconnect both ends of the starter wire and you can start it with the key. I would disconnect the power to the alarm or your lights are going to flash at random. The factory alarm (just in case it is the issue, but that isn't likely) is located behind the radio and ashtray.
Now im not sure since the manual says your model has the same alarm system as the 328i and on the 328i you can remove the module to disable by doing the following. you can unplug the control module. It is located under the glove box. Climb under the dash on the passenger side and remove a few screws on the trim panel under the glove box. Theres a black control module with a green connector. There should be a lock tab on the connector. press the lock tab and pull out the connector. The alarm should now be disabled. But if it has the special transponder key this may not work.
But if the only reason you want to disable it is because of the motion sensor setting of the alarm for no reason there is a solution for this. To disable the motion sensor, hit the lock button to arm, then hit lock button again within four seconds to disable motion sensor. Red light on rearview mirror should flash four times, then pause, then start flashing on regular intervals. this is most likely the reason if your having the issue where the alarm goes off every 20 minutes. If you want to completely remove it below is a wiring diagram taken from the manual for you alarm system. this is from the manual its the alarm wiring diagram.

I just found out that the problem on our 1998 windstar was the chime
switch attached to the ignition switch. This chime switch when
dislodged will short and act as if the keys are still on when the door
is open ( thus sounding off the alarm). I had a hunch that the problem
was close to the steering wheel because the alarm would stop if I
change the angle of the steering wheel a couple of notches up or down. I
guess when i did that the chime switch that i'm pertaining to get reset
to the right position and stops the alarm. when i opened up the
steering wheel housing around the ignition , the chime switch fell, it
had a blk wire I think, and I saw that the clips on it were kind of
melted thus not sticking to its right position. I just had to remove the
ignition switch for a while and replaced the chime switch with the help
of a zip tie wrapped around it. then I placed every part back together
and no chimes... also I did this all while the battery was disconnected
because i needed the ignition switch to be in the on position to get it
off the steering wheel. Good luck guys!
thgis problem is caused by one or more defective door ajar/courtesy light switches or sliding door contacts, since these switches are very hard to replace as they are located inside the doors on the door latch the best thing to do is have the dealer hook up a body module scanner, it can ID the faulty switch, then i f wish u can change it to save money, the switches are about $15 each, there are 5 of them

something is obviously wrong with the wiring try reinstalling the old system and letting a n experienced mechanic install this other one for you wiring is everything
Try replacing the Air Flow Sensor, it's the switch looking thing, to the right of the air filter box; I think it runs about $6-$10s. Good luck.
For the doors alarms and dome lights, try: spraying the inside and around the inside of the center door latches with WD40 or silicone lube. Hoping it's that simple.
The signal from all the door switches is fed to the factory radio. From the radio, the signal goes to the dome light. When the radio is removed, the dome light does not work since the circuit is "cut".
Fortunately, there is a very simple workaround this problem. If the car does NOT have a factory alarm/ keyless entry, all you have to do is tie two wires together.
There are two green plugs. Get to the one that is plugged into the radio (if you have both green plugs going into the radio, then you DO have a keyless entry system).
Tie together the Green/Black (at the corner of the plug) and the Green/Red (3rd pin, opposite corner, same row).
Before tying the wires together, test both wires. With the radio plugged in, both wires should get a ground when a door is open and nothing when the doors are all closed. Once you have determined that they are in fact, the correct wires, unplug the green plug from the radio. If the dome light still works, you do not have to worry about it. If it doesn't, temporarily jump with a wire both pins at the plug. If the dome light functions correctly, then you can permanently jump the wires together. The preferred way to do this is to strip some insulation on the wires, solder a jumper wire and insulate with electrical tape.
