2001 Mazda 323 or Protegé or Familia BJ Chassis Non-US

Hi, indeed there are several topics already with the damn 323 or Protegé (depending on which country are you).

Straight to the point, I don't have a fancy alarm, is one of those chinese ones. I bought it in a hurry since I just bought the car and it did not have any kind of protection system besides the door locking system.

Now, I did mess up before even finding you guys, because I had the service manual of the car and the wiring diagram, spent 2 days planning and supposedly all was going to be easy... for a 6ft tall person is not easy to install an alarm, specially in tight spaces.

Anyways, so, what I had thought was to tap to the door actuator from the door control system and that would be it... WRONG. As many times I had read now, this is a one wire system, the thing is, which is the wire and how do I wire it?



As you can see, this model does not seem to be completely the same as the US model.

Next, is what I had in mind, but is it WRONG, using creates some short and the wires start to get hot also.



The thing is that, the diagram above, does not match the non-US model, since I'm missing pins: B, H, I, J. I know some are not there because I do not have the factory alarm.

The problem so far for the door locking, pin K show 5V when locked and 0V when open, and pin L show 5V when open and 0V when closed.. Those pins appear as empty on the wiring diagram in the service manual.

Pin F does not show anything, I mean literally no voltage or something like 0.1 when actuating the driver side door lock, so I do not know how to interpret this. Is this the ONE-WIRE that I'm supposed to tag into? could it be pin F (green/red wire?)

Moving forward, this is the diagram that I have from the alarm that I bought, again, sorry indeed, just a cheap china made, I promise to change it for a better brand name next year.



And a close up of the wiring of the door locking from the alarm side:



Now, I see that you guys mentioned an 1500 ohm resistor, the next question is: which wire is the trigger of the door? and how do I solder this resistor to the signals of the alarm?

I also see this diagram: JBS alarm diagram one wire system

And this one:Bulldog diagrams

I going to suppose that for the closing signal (white wire on the alarm) goes to the one-wire WITH resistor and the opening signal (white black wire on the alarm) goes WITHOUT resistor to the one-wire. The question is, where is this one-wire? could it be that one that showed 0.1v?

So far I have wired most of the stuff of the alarm, and so far I have to wire the door locking, the door trigger (which I know is a black blue wire but... I need to disassemble more since I do not fit quite in there... you know... 6ft tall here.

Here is a link to Directed TechTip 1041 :   https://www.the12volt.com/installbay/file.asp?ID=1213

It has very good with info on the various door lock systems. From you wiring info, it looks like a Type H system. The TechTip describes how to determine the correct resistor value. The only hard part will be setting up the wiring for your system and it's internal relays. The vehicle connection point could be on the wire between F and K if you wanted a single pulse to unlock all doors at once. Use the wire between points H and O if you want Progressive Unlock ( first unlock pulse unlocks the drivers door, second unlock unlocks the rest of the doors.

Soldering is fun!

Forgot to mention I do not have the keyless entry system, but after seeing the tech tip 1041, now I understand, and after matching the info with the service manual, now I understand the resistor thing, I need the resistor to lock and no resistor to unlock, on the F pin.

Now, the K and L pins, since there show 5V, I assume there is a BCM, so I won't mess with them, do not want to burn any computer thingy.

Tomorrow I will get the resistor and try.

Then... to disassemble the kick side panel and search for the door trigger.

Thanks for the info.

Power Lock      lt green/red      - 1500 ohms      module high in driver kick           
Power Unlock      same wire      -           

Guys... guess what?

the damn green/red... seems to be not connected to the door system. I took the green/red out of the connector (it has a nice tab system to take the wires out without cutting) and actuated the door lock and all door opened and closed WITHOUT the green/red connected to the module.

Now check this out:

When I open the door lock:
Gray/Red has 5V
White/Black has 0V

When I close the door lock:
Gray/Red has 0V
White/Black has 5V

So... that means that the wiring is not quite, standard as the model I have is non-us.

Since those two have 5V, that means that they go to the ECM or the Door Lock relay has some 5V circuitry...

Help please :oops: :( :( :( :(

So, finally I installed the car alarm minus the door locking system.

Why?: the driver's door DOES NOT have the oem actuator or any actuator, what it seems to have is a dummy actuator that signals the 5V to the door locking module:

When I close the door lock:
Gray/Red has 0V
White/Black has 5V

Now, since this models is non-us, DOES NOT have keyless entry, DOES NOT have the actuator on the driver's door, using the wiring diagram of the site helps only to install the alarm minus the door system.

BUT, using my diagram WHILE DISCONNECTING AND REMOVING the door locking module AND ADDING an actuator for the driver's door, gives you the full alarm with the door locking controlled by the alarm.

I'm satisfied, since the alarm is installed at least, partially, but it is.

One note: the wiring to the doors DOES HAVE the wires for the actuators on all the doors, so you can install some generic or non-oem ones, but I will do that by the end of the year... if I survive this pandemic too :P

Thanks for the guidance guys.
