new here with a problem with bmw

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 (+) This is the 12 pin Factory Alarm prewired harness layout Locking Tab 1...2...3...4...5...6 7...8...9.10.11.12 Pin#.............Function......................... ........Wire Color 1...........Constant 12VDC....................RED / Green or RED / Gray 2...........Ignition 12VDC.......................Violet/White 3...........Chassis Ground......................BROWN / Orange or Brown 4...........(-) Driver Door Trigger............BROWN / Gray 5...........(-) Passenger Door.................BROWN / Blue 6...........(-) Rear Door...........................BROWN / Black or BROWN / Violet 7...........(+) Horn Trigger......................BLACK/ Blue 8 Not Used 9...........(+) Lock...................................WHITE/ Red 10..........(+) Unlock................................Blue/Red or Blue/Brown 11..........(-) Trunk Trigger......................BROWN / White or WHITE/ Brown 12 Not Used

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.
