I was wondering if anybody has worked on this car recently.I've heard conflicting reports that most of the wires I need for a alarm are found at the factory alarm plug behind the glovebox and lock/unlock is a 5-wire.Can anybody confirm this??? ------------- installing, one day at a time..

| Power Lock | WHITE/ red | + | factory alarm plug | | 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. |

Thanks for the reply I see directechs saying it's a positive signal but the12volt says 5wire for unlock and my co-worker said he remembers having a hard time with directechs wiring diagram on that car so I just wanted to double check before I got into this thing

E36 Was POS 2 wire lock unlock. Increase lock time (5 secs for windows only, 12 secs for windows roof). You can also pick up the leads at the quadlock on the body control unit,behind the glove box. This will be the middle plug and pin 4 (bare is lock, 17 blue/red unlock), also separate door contacts these are in the r/hand quadlock, same location, BROWN / grey and BROWN / blue or brown / YELLOW all with yellow dots, diode together. Arming and disarming at those points will control the factory alarm. No dome light supervisiion required, remote lock and unlock will control them.
