there are a lot of variations.... you will have to decide which is relevent

Hi, after playing about for a bit it looks like the central locking needs a 12v + signal to lock and a 12v - signal to unlock, anyone done this before and agree with my findings?
Cheers

what you will find is the switch (or relay) reverses the wires

so +12v wire goes instead to ground.. and ground wire goes to +12v when switched

or +12v wire to +12v and ground wire to ground when switched the other way

 

In case it helps anyone else the central locking is negative pulse for lock and unlock to the white cable with the blue stripe on the plug in connector in the drivers footwell, spent a bit of time working through the cabling today and now have remote central locking pulsed off my alarm,

 

so, does that mean nobody has access to the wiring diagram? I'm looking for the same thing for my 112cdi if anyone can help?
