Central locking

Hi I need help to find the cental locking locations on a J Reg SVX with remote control central locking with sensors on door and dashboard.

I have fitted an alarm system on the vehicle and would like to know how to connect the alarm to work central locking, and if it is positive, negative or motor interupt central locking. I think I can hear a relay above glovebox area, but had difficulty removing this.

Please could someone help to identify the correct loaction and wiring colours and type of locking on car, for me to connect the alarm system to work central locking instead of the vehicles remote.

I am also fitting 4 window closers and nay help with the correct colour wires for closing all 4 windows would be appreciated.

Thanks

Martin
