Hi All, looking for help, have fitted a Disco 300tdi door to my 200tdi and need some help with the wiring. I am only interested in coupling up the No. plate lights, wiper and heated rear window, so I require the wire colour codes for those items for both doors. I believe I am correct in thinking the primary earth wire is Black and the rear sidelights are Red/Black. Does the Red/Black continue into the door for the No. plate lights and what are the colours for the heater and wiper? I do not want to strip the door panel at this stage if I don’t have to so answers appreciated – thanks.

Red/Black (RB) is number plate and sidelight and trailer socket sidelight.

Green/Purple (GP) is stop lights.

Red/Yellow (RY) is fog lights

Heated Rear Window is (NP) Brown Purple

These are for the 300TDi

Hi Peter.
I have now got the No. Plate lights working but I am still stuck with the rear wiper motor. I have a Haynes manual for the 200tdi but the actual wires for the rear door do not match for the wiper as per a 92 disco. The rear screen heater and washer are working so it is just the wiper motor. The Haynes manual refers to a Light-Green/Grey and Brown to the wiper with black earth as per norm but I have no corresponding wires in the 300dti door.
I have also been working on the front doors today (also salvaged from 300 tdi- 96 Disco as per the rear door) and have got the window winders working but have got stumped by the ‘trigger’ wiring in the driver’s door for the central locking. I have a Brown/Pink wire, on both front door supply on the 200dti loom which does not match up with any wiring in the door.
Much appreciate any help
Martin

Remember that on a 300 the Multi Function Unit controls the wipers a 200 does not have a MFU.
Also the 300 has a seperate central locking ECU to provide a signal wires for remote central locking, interfaced with the alarm ECU, which the Haynes manual or schematics above do not show a 200 does not have one and its combined within the alarm ECU. As for a standard CL a perminant 12v and earth/ground is all you need at the drivers door actuator (master).

Therefore you will have to modifiy wiring to suit as required.
