    Hello All,
    I am new and I hope my search for an answer has brought me to the people with the knowledge.

    Right...
    I've got a P reg ('96) 3 Series and I have bought an aftermarket keyless entry system after the key has become so worn that it's becoming harder to open the doors. While it still works fine in the ignition and is a cheaper option than a new lock set I'm going to accept that if my battery goes I may not get in at all...

    I have searched for hours now for a solution and the only conclusion I have come to is I should have bought a stellar system...but I didnt so I'm hoping you guys can help.

    The system I have bought has instructions but are as useful as a worn key...

    I'm pretty sure that after tests I have a Positive trigger system?? right??

    I need to know where will I find and what colour is the close signal wire and the open signal wire??

    Can anybody shed some light??

    Many Thanks in advance

    Not exactly sure what you're after. Is the car the one listed in your spec's, or is it a 5 series. Anyway, have a look at this thread, later on in it, I have posted some diagrams which may be what you're after

    Sorry typo, it is the 3 series.
    I need to wire in a brain unit to control the keyless entry fobs.

    The brain unit has the usual suspects off Ground & +12v.
    It also has a a pair of wires for the close signal one wire goes to a +12v and the other to the close signal wire. There is another pair for the open signal. So basically a pulse is sent down the corrisponding pairs when I press the specific buttons on the fob.
    Now I'm assuming that somewhere in the car there is a wire that I can tap into that triggers the open locks and one that closes them again.

    I hope I am making sense.

    Many Thanks

    A second hand lock barrel from a scrapyard costs peanuts.... and would have been a more effective fix

    Do you have the central locking button inside the car. If so you could possibly use the wiring from that.
    Each of the front door actuators individually send lock and unlock signals to the control module. The wires are white/black (lock) and white/green (unlock). The boot lock does the same and the wires are white/blue (lock) and white/green/yellow (unlock).
    This is just my interpretation of the wiring diagrams so I can't guarantee how the system will operate with your new keyless entry system. It's your call but I hope you get it working.

    I got it sorted, took glove box out and found the central locking module.
    After various multimeter tests discovered what was what.
    Shame I didnt wait till tomorrow before I started again as you are spot on with the colours, could have saved me some cursing lol.
    Anyhow it's all working now.
    Many Thanks
