Ke70 k50 gearbox wiring question

[johnny2]

Pulled my gearbox out to reseal it and need to know what each of the wires are for, and even a wiring diagram for it would help.
Thanks

Reverse switch by the looks of it

There are 3 different sensors they wouldn't all be for reverse would they?

The one in your hand is the reverse lights, the other 2 i'm not sure... check continuity between the casing and the wires, they could just be earths?

The gearbox is back in the car now but when I had it out they were exactly the same sensors as the reverse sensor, but they just engaged at different gears/neutral
