You can either use an ohmmeter and hook one end up to the door wires, and find the keyless entry box that is usually located under the dash panel and find out which wires are for what.

The only way to do this is with a service manual for that specific car. The lock system is controlled from an electronic control module that receives a radio frequency signal from your remote.Without a schematic and color code for the wires, it would be very difficult even for a technician.
The service manual will have the information and schematic for that module. It will cost you around 20.00 dollars.

The keyless entry/alarm system was standard only on the Active Pkg 318ti in that year. Even that one was port-of-entry installed. You can get the same kit from a dealer and install it yourself with the instructions that come with it. As the sticker implies: your car is pre-wired for easy installation. Not too difficult though I've never done it on a ti. Most likely access to the installation/wiring is easier on the ti than an "normal" E36 that requires glovebox removal. If it were me, I'd be doing the factory kit, depending on the deal you get on the kit.

Each remote transmitter had a unique ID code and the car can store up to 4 ID codes.

Preperation
1. Close all doors,trunk,and hood.
2. The security system must be in disarm mode and key must be removed from the ignition key slot.

Enter Code learning mode
3.Open trunk and leave it opened.
4. open the driver's door and sit in the driver's seat
5. Close the driver's door.
6. Cycle ignition switch 5 times between Off and On (DO NOT START ENGINE)
The red status light will illuminate continuously, and the siren will chirp once to indicate that the code learning mode has been initiated.
The ignition switch cycling must be performed within 10 seconds.
The sequence in steps 1-6 must be performed within 45 seconds.

Register/Delete ID Code(s)
7. Open driver's door (remain seated in driver's seat)
8. Close driver's door
9. Press and relase any button on the remote you wish to register into the system. The status led will shut off momentarily to indicate that one id code has been registered.
10. Repeat steps 7 to 9 to register the remain the ID codes.

Exiting code learning mode
11. Open driver's door and exit vehicle, leaving the door open.
12. Close trunk.
13. Close dirver's door. The LED will turn off and the siren will chirp once twice.
14. The initializaiton procedure is now completed; test all remotes to confirm operation. ----------- I installed the bmwalarm.com keyless entry system this morning. There were a couple of hitches but I was ultimately successful.

There are two things that I would warn others about if they decide to go this route:

1. Although it is called "plug-and-play", it really isn't. I expected to unplug my BMW keyless entry box (which came with the car but was not working) and plug this one in. That was not the case. You need to unplug the OEM wiring harnass that plugs into the "alarm port" located under the glove box. The harnass that comes with the bmwalarm.com system does not have a plug that goes into the alarm port. Instead there are 8 wires, each with a connector that plug into the alarm port individually (red wire to pin 1, yellow wire to pin 2, etc.). I decided to cannibalize the connector from the OEM harnass and hook it up to the new harnass to make this a cleaner and more reliable setup. One tip for others: the alarm port is difficult to reach, but it can be unmounted for easier access by sliding the entire connector forward after releasing a plastic catch. Shine a flashlight in there and it will be obvious.

2. My other, and more major, complaint is the installation and programming instructions. Although written in English, they are nearly incomprehensible. On the installation, several pages are spent on the mechanics of removing the glovebox, knee bolster, etc. but the electrical connectivity is not very well detailed and complicated by the fact that the instructions are covering two different models which connect differently. There is no troubleshooting guide. Once installed you have to program the keyless remotes and set the various features of the system. As an example, to enter programming mode you turn on the ignition and press the "valet switch" 3 or 6 times depending on whether you want "designated mode" or "auto mode". It turns out that "designated mode" means single button lock/unlock and "auto mode" means one button locks and the other unlocks. There are six features that can be enabled/disabled but I couldn't figure most of them out and ended up doing a trial and error discovery process. This was all made more difficult by the fact that the manual says you will hear confirmation "chirps" as you program the unit but I never heard any chirps and had to rely on the LED and carefully following the instructions.

Bottom line: I now have a keyless entry system. The fobs are about the same size as the orginal BMW fobs and the system works fine. The installation was a bit of an adventure. I would recommend this system only to the fairly brave Do-It-Yourselfer. check out and reply.will be always waiting to help you.when ever you require more help.please keep updated.please do rate the solution if helped.thank you for using fixya.

Hi there,

Well, i have a link to help you.....
Please follow the below link -

Good Luck!!

Thanks

Hi ,to do this you need a wiring diagram of the alarm/cenral locking system the car uses a CAN-Bus system so unless you have an oscilloscope you won`t be able to see the pulses as they are in microseconds,if the car is under 3 years old give it back to the dealer to repair free of charge if not find a good BMW garage with dealer ship level diagnostics (Winstar BMW) you can then go into the system and find any fault codes and actuate the different circuits to find the fault.Be warned if you power probe the wires you will cause thousands of pounds worth of damage to the CAN network and potentially cause an electrical fire,if your not sure ,Take it to an expert it will save you time and money in the long run

If you cannot lock or unlock the doors, the first thing I would check/replace would be the battery in the key fob/remote. You may have to take it to the dealer to have a reprogram done to the module which controls the door locks.

The problems is not that clear.. but i guess you asking how to trace wire of the lock and unlock for keyless entry.. in BMW series (318) cars they are located in four colors. orange/purple or green/black
Positive (+) drivers kick panel
Power Door (Unlock) (+) Door Unlock pink/purple
Positive (+) drivers kick panel hope that helps..

The answer is quite simple: I take a close look at all wires on the other door. I measure resistance to each wire on the WORKING side. I go back to the broken side and detirmine the bad wire. It takes time Kimosabe. But that my friend is the secret to how it is done.

is this a BMW factory kit you are installing? if not you are going to need a factory wiring diagram, but short of that locate the power lock relay, that is where you need to tap in for an aftermarket system. if this is a aftermarket system please give name and maker of system.

I don't know what you have already covered but, Generally to trace a wire, first find the wire on a schematic that lists color code and color changes along its pathway. What I have always liked least about schematics is that they tell you a wire or component is there but not where. (none I've ever seen do) It seems that from what I can see that you have written, there is no power inside the door...The most common problem that causes that is where the door meets the body at the hinge end, there is a rubber boot containing the harness...most wires break right there. Sorry I can't offer much more but to diagnose electrical work without actually being there and doing testing is next to impossible (it's not easy even in person) And, entry systems are generally considered part of your security system and often are kept "secret" or anyone could defeat them. Then, tracing has to be done inch by inch.
Good luck.

whne you run out of help let me know and I will tell you where to hook up the wire, there is a control module you need to connect to to operate all locks.

It sounds like you are trying to find a wiring schematic to trace the electric door lock system?
If so, the link below will lead you to a web site that will show you the wiring.
Good luck, let me know.

Hi there ,

The basic diagram below should allow you to connect the keyless entry module, it is for US/CA models:

Legend: ITEM - WIRE COLOR - |POL| - WIRE LOCATION
| 12V red/wht or red |+ | ignition harness
| STARTER blk/yel or grn/blk |+ | ignition harness
| IGNITION green |+ | ignition harness

| POWER LOCK white/red |+ | factory alarm plug *1
| POWER UNLOCK blue/red |+ | factory alarm plug *1
| PARKING LIGHTS + gry/pur, gry/ye l *3 | headlight switch
| PARKING LIGHTS - blue/green (hazards) factory alarm plug *1
| HEADLIGHTS yellow headlight switch
| DOOR TRIGGER|*4 factory alarm plug *1
| DOME SUPERVISIO |comes on with unlock
| TRUNK/HATCH PIN brown/white |- | factory alarm plug *1
| HOOD PIN| purple/green |- |*6
| FCTRY ALARM ARM *7
|FCTRY ALRM DISAR *7
| TACHOMETER| black instrument cluster *2
| BRAKE WIRE| blue/red |+ | at brake pedal switch
| HORN TRIGGER brown/red |- | steering column
| WIPERS blk/gry and blk/blu |- | steering column
| LF WINDOW UP/DN|blk/wht - pur/wht |A |body electr control mod *5 |

| LR WINDOW UP/DN|blk/yel - blu/grn |A |relay module *5 |
| RR WINDOW UP/DN|wht/yel - blu/red |A |relay module *5 |

NOTES: This vehicle is equiped with the EWS II immobilizer system that need to be bypassed when adding a remote start. Use DEI module 555B. *1 The alarm plug is a black 12 pin plug located just behind the glove box. It is mounted with the pins facing you atop a vent just to the left of the body computer. Other wires at the alarm plug are: 12V- red/white; Accessory- purple/white; Siren- black/blue; Ground- brown/orange. Do not use the power sources at the alarm plug to operate high-current devices. The other side of the siren wire is mounted in a 2 pin plug at the passenger rear corner of the engine compartment. The other wire in the plug is a brown ground wire. DEI recommends attaching the siren at this point. *2 The wire is located in a white connector behind the instrument cluster. Do not unplug the white connector with the ignition on or turn the ignition on with the plug disconnected. *3 These wires are the separate left and right parking light wires. Use both wires and isolate each. *4 Door triggers are brown/gray for the drivers front door, brown/blue for the passenger front door, and brown/white for the rear doors (if equipped). Use all three wires and diode isolate each. *5 The body electronics control module and the relay module are located behind the glove box. When using a 530T and locking and unlocking with the key will cause the windows to travel full direction. The 529T will not alter the factory operation. *6 Located in a single pin connector next to the factory alarm plug. *7 If equipped with a factory alarm, the alarm will be plugged into the factory alarm plug. The only way to arm and disarm the factory alarm is with the factory remote. If your planning on using the 8360 pre-wired alarm harness the factory alarm must absent or removed.

From 12Volts.

If that is not enough, then the best thing to do is getting a complete wiring diagram for your car.
If you register onto this forum you can get a free wiring diagram for the 318Ti 1996-US model, that is not much different from the europena one (on UK models driver side features are inverted).

A good thing to do when you decide to DIY your vehicle is also grabbing the repair manual for your model, with full diagram, and illustrated step by step repair procedures: BMW Automotive Repair Manuals.

If my comment had been helpful, then please do not forget to leave feedback, answering, researching and typing takes its time.

thanks.

The unlock wire is Green/Red, the lock wire is Blue/Pink. Common is ground which is the Black wire.

you are in the right area from your pictures of glove box veiw
the left hand connector X13252 is the outputs to door lock motors, pin 1(lock), pin 9(unlock), pin 2 is earth back from door lock motors.

connector X13253 (middle connector) is input from master switch (pin 1 on switch colour RT/GN/GE pin 19 on BCM) eg power = lock request, no power = unlock request
