Need wiring diagram for door lock

[Simon2]

Hi guys,

as i still have the problem with my Central Locking Unit ( both door locks and alarm not working (with the fob), all other functions are fine), i want to install a third party central locking unit (maybe alarm also) just to open and close the doors with a fob. The door locks originally are conneted with a nine wire connector. First question is:

- if i disconnect this connector from the door lock and instead wire the new central locking wires to the door lock, will this cause a problem to the porsche central locking unit?

- the manual of the new CLU says, Porsche uses a "negative trigger" to open / close the doors. If so, which wires do i need to connect with the two wires from the new CLU?

Thanks a lot,

In the meantime, i found out that the brown/red wire connected to the doorlock is the signal for openening the lock and brown/white for shut the lock - if you give a (-) signal.

But even if i do this with a little wire, i get a "feedback-noise" from the central locking unit but the doorlocks don´t open or close.

I still have the Durametric fault 46 - "syncronisation" and 60 - "not able to close". Is it possible, that both door locks are not working...?

The Porsche guys said that the CLU might be out of order. But every electroninc feature works fine - even the doorlock for the back trunk. Only the two door locks don´t work.

Any idea...???
