Hello folks,
Could someone please tell me (send me a picture!) where the heck is the alarm connector in my E34 530i Touring? I took out the rear seat bottom and looked for it, but couldn't find anything suitable.
AFAIK it should be a 12 pin female connector under the rear seat somewhere on the right side of the car (which is where the battery is). I looked for it and even peeled back some of the carpet, but couldn't find it.
On the left side (driver's side) there is a black box with relays and fuses. On the side of this box is a 12 pin male connector. I probed it with a multimeter and the pins didn't make any sense (no door switches), so this is probably not it.
If there is no alarm connector or it's hidden so that I can't find it, I need to know where I can tap into the central locking lock/unlock wires and door position switches. I took out the mini "glovebox" left of the steering column and had a peek, but couldn't find suitable wires or loose connectors in there, either.
I suppose I could take out the panels in the driver's footwell and look for the door wire bundle. That obviously has the central locking wires and driver's side door switch, but I'd like to also have the passenger side door switch and rear door switches connected to my alarm unit. :)
If I understand correctly, the black box under the rear seat controls central locking. I'm just getting confused by the spaghetti of wires in that area. Does anyone have a wiring diagram for that box?
