TD5 2004 Manual Reverse lamp switch position

Hi all, I hope I’m posting this in the correct place!
Recent purchase Disco TD5 2004 manual - I’m struggling to locate the reverse lamp switch.
There are no wires coming from any where around the gearbox area, (including none from transfer box oil sensor? Low ratio switch).
The loom from the connector in the console along with the grommet has been removed.
Not even sure if a switch is fitted, even fitted but without wires attached, so I don’t really have a starting point.
I’ve now got a replacement lead (from an auto box but can utilise).
Searched the net, YouTube and the manual which isn’t clear to me.
Can’t any one help to direct me to its position, sketch or photos anything would help.
Cheers.

HI, watch the red arrow

Hi sierryfery, mystery,
Thanks for the images, they seem to show the same switch/coloured wires, but in different positions on the gearbox housing?
I need to take a closer look on mine.
Cheers Steve

The reverse lamp switch is where the red arrow points in post nr 2, mystery's image shows only the connector(C0167) not the reverse switch, that switch below C0687 is the TB temp switch which was fited only on NAS modells

Hi sierrafery, ok, thanks for coming back to me on this, I think there may be the remains of something in the position you’ve identified, most bizarre where it all disappeared to!!!!!
