Disco 1 1993 wiring

Hi i'm having a problem with the disco i got a while ago, central locking not working, can't find a module. Does it have an alarm, has a bonnet switch and an led on the dash binical top right hand side.
Have downloaded rave cd but the wiring diagram does not cover per 1995. Pulling my hair out oh i dont have much lol, found a bunch of black wires under the dash drivers side, and a socket fitted to the cover below the streering wheel not original. Do these wires go to a missing alarm moduel/central locking unit ???.
A good wiring diagram would be good i will post some pics tomorrow.

Hope some one can help me

Is there a name on the socket under the dash with the black wires coming from it....Sounds to me like it may be an aftermarket immobiliser.

Thanks for the reply, have checked no markings on plug see pic's , in the wires there are diodes and resistors in line on a few wires. Also see pic of the socket, any help would be good can i remove all this wiring.

A wiring diagram for the car would be great where can i get one not on my RAVE disk.

Thanks Steve
