Steering Column Ignition Key Wiring Question

I went to start the old girl and the ignition key just turned in the barrel. So I undid the steering column/wheel lock/ignition (scarily easy) and found the switch at the back had fallen off.

Inevitably in trying to refit the switch the heavy ignition unit slipped out of my hands pulling the wires off. (note to self - always take a dammed photo asap!) So the question is

Where do the four wires go?

Petrol or diesel?
This is pic of mine which was petrol and now diesel some extra wire just ignore.

Do you have a copy of the land rover manual? there's a good drawing in the back.

Answering my own post from page from page 80-30 of the manual

Petrol Engines
Brown leads to Terminal 1
White leads to T2
White red to T3
