Wiring Diagram for a 84 classic

Help please.

I am tyring to find wiring diagrams for a 1984 RRC, mainly the 3 speed auto wires.

I have put a 1988 EFI engine and 1991LT77 gearbox (disco V8 one) and need to find a better one than Haynes and don't seam to be able to download RAVE.

If anybody knows where I can get a good diagram, preferably colour one I would be most grateful.

Cheers

Or can somebody tell me what the 3 wires do that go to where the selector cable goes, think it's the green, green with white stripe and black into a plug. I know which are the handbrake and the transfer box (although don't know what it does) then have a round plug that the writing has come off and can't remember where it came from but the only one left (I no longer have the gearbox)

I am trying to find the reverse wires and the wires that stop it starting when in anything other than N or P

cant you just test it ,theres is only the 2 functions

Not wired up the engine bay yet as no wings on the front and was wanting to wire up the gearbox so I can put the floor back in. The steering column in out and all lights are off as well.
