    I have a bit of a problem, when I removed my central locking relay for testing and then I lost the diagram I made for how it was wired in, can anyone help my electronic skills are limited pretty much to plug fuses

    here is how my lock is wired

    Vacuum pump door lock
    Blue
    ----------------0 ------ 0------------
    Red (main) feed
    ----------------0 ------ 0------------
    brown
    ----------------0------ 0------------
    if all wires are connected the locking works with the key......
    when car is unlocked then red+blue are connected by switch
    when locked then red+brown are connected by switch

    relay type is http://www.audio-discounters.com/451m.html

    the relay has several wires which were wired in...
    violetblack = lock/unlock normally open #87
    whiteblack = lock normally closed #87a
    blueblack = unlock output #30

    the following two are just connected to each other and not into the door wiring..
    brownblack = unlock normally, closed #87a
    greenblack = lock output #30

    there is also a violet with a fuse I remember this was connected to the red wire..
    can anyone please complete the wiring diagram

    Update :

    Thought I would try something with the wiring, I kinda remember only one wire was split and the rest where in one piece just had the relay merged in so I split the blue wire and wired the blueblack (unlock output) to the blue wire going to the pump and wired the whiteblack (lock normally closed) to the blue wire going into the door, I then joined the violetblack (lock/unlock normally open) into the brown wire I knew where the other wire went which was to merge into the red..

    Bingo job done everything working fine..

    thanks to anyone who tried to help...
