new here with a problem with bmw

A little introduction, My name is Sam. I been on this site for sometime looking at info about wiring an alarm and when I finally thought I got, I don't. So, I finally decided to register. I have a 96' BMW M3. The main problem I have is wiring the alarm to work with my central locking system. I'm really having a difficult time making this work. Just wondering if anyone else with BMW's have had any problems and can chime in and help? Thanks in advance.

Oh btw, Crimestopper sp-100 wiring into an 1996 BMW M3 Coupe

You have two ways to do it on US vehicles;
1) With factory alarms, go for the alarm module, WHITE/ black - lock and blue/red - unlock.
2) Without the factory alarm remove glove box, control module with the plugs facing you, one rectangular with heavier cables, 2 x quadplugs, middle plug, either yellow or purple, pin 17 blue/red + is unlock, probably empty socket opposite, pin 4 is lock +. If there is a wire at that point it's white with a red trace. Extend lock time pulse for window/roof closing* TEST.
The plug to it's right has the door and possibly trunk triggers.
*Make sure your 1 shot facility is still working.
Bulldog has a free access site, check that as well.

What you're saying is that theres another harness instead of the prewired for alarm harness? Do you have any pictures and can you be more specific?

If you've found the prewired alarm plug, what's your problem?

The problem is actually getting the lock and unlock to work with my alarm. I'm not sure if the module is messed up or what, cause wiring my lock(-) and unlock(-) to the prewired harness is not working. I believe my prewired harness for the lock and unlock is (+).

Do you thinking using relays would work?

If you go to the factory alarm plug, it's neg pulse so you won't need relays. Check your alarms output to see if lock and unlock give you negative pulses as they should.

On the manual it says (-). This website is confusing cause I was looking up wiring diagrams, on 1997 3 series it said (+) for lock and unlock, then I went to 1998 and it says (-) for lock and unlock.I looked on bimmerforums and they said it was (+). https://forums.bimmerforums.com/forum/showthread.php?t=1188309 .Anywho, I tried wiring my lock and unlock directly to the factory alarm plug and still no luck..

92 to 98, E36, pos locking at the quadplug, that's what the European versions did. 98-05 E46 Neg locking.
In the US there was a factory alarm on the E36. This part used neg locks with the same colours as the E46. So on your model you have 2 choices which adds to the (your?) confusion. Simply test, throw over the latch on the door you keep open, shut other door and poke something into the striker so the car thinks the dome lights have shut down. To sum up, ig you have the factory alarm you have a choice of 2 lock types.

I've done a test, and it tells me the wires from the alarm is positive. I've also tested the wires from going to the motor, I ground my test light, and every time I hit lock and unlock, it would light up stating that its a (+) pulse. And since my lock and unlock from my aftermarket alarm module is (-), using the 3 wire positive door locks or 5 wire alternating door locks would be appropriate for this situation?

A motor wire normally sits on ground and goes pos. Your biggest problem is that you don't know what you're doing. Go for the triggers. Have you identified them? What colours are they. You are messing this up, I don't know of any 2 wire alarm lock wires that are normally pos.

Ok, let me try to make this clear cause I'm getting more confused when I'm reading your replies lol.

Alarm Module
GREEN / WHITE = Lock (-)
Blue/white = Unlock (-)
Green = Door Trigger (-) which I've already wired to my door switch. Works fine.

Factory Alarm Prewired harness
WHITE/ red = Lock (+)
Blue/gray = Unlock (+)

OK, thanks for that last post, I think we're getting somewhere now.
I apologise for the confusion but since I've never seen the US version I was going on Bulldog and Directechs which stated that although the locking system used pos pulses, the factory alarm plug used neg!.
Of the relay diagrammes you originally posted,the first one is correct BUT turn the left relay around so that the neg pulse from your module goes to 85. Then place a diode* across 85 and 86 on each relay with the band towards the pos side to protect your unit.
Now here's the clever bit. does your unit have a timed aux output?
If so set it for 10 secs., or 15 if you have an electric sunroof and run it to 85 on the lock relay. Every time you press that aux, it will deadlock the car and close the windows/roof.
*1N4004 diodes.

Thanks for the advice, and I'm glad were on the same page now lol. Would you make a diagram of how the wiring should be? So when I do get started on this again, I won't have to think real hard on it when I shouldn't.

Relay 1 Lock Alarm lock wire to 85
12V+Constant fused at 3amps to 86 and 87
Output to car's lock trigger wire (WHITE/ red) from 30
If you have an aux on your alarm that you can set up as timed, feed it to 85 on that relay. It should close the windows/roof.
relay 2 unlock.
alarm unlock wire to 85
Same fused line as above (shared) to 86 and 87
Output to car's unlock trigger (blue/red) from 30
Don't forget to diode across the coil, band of diode towards the + side (86).
If there's a remote start involved, let me know because you will need to know some BMW specific details that aren't in any guides!

I appreciate it!! Actually my alarm does have a timed aux output. What is all required for it, cause the package did not come with any extra hardware. And how would you install this?

Opps sorry thats the wrong one, I was looking at the wrong alarm lol. It seems that my alarm doesn't have the timed aux output. Sorry about that.

Does it have any aux outputs? I'm about 3500 miles away over the pond and I'm not familiar with the brand! Two answers:
1) Take an existing aux and run it through a DEI 528t set to the right time, run a parallel wire off your lock wire through a relay to interlock it with your ignition, i.e wire from lock side to relay 30, relay 87a to 528t, ignition to 86 and ground to 85. Run a wire to the unlock side from this wire, place a 1N4004 diode inline on that wire with the band towards the unlock side.This means that if you lock the doors when ignition is on, either manually or auto lock it wont close the windows or deadlock but if you arm the device it will automatically close the windows and deadlock the car. Post me if you want the remote start info.
