Hi Doug, yes the internal detail of the double pole brake switch is shown on the exterior brake and reverse lamps part of my wiring diagrams too
I've checked the supercession lists on my EPC, and the original white double pole brake switch has now been replaced with XKB000022A, so a cheaper Land Rover alternative is
XKB000022
So I would start by making sure the switch fitted to your car is the correct one, then take it from there
