Thanks for the sound suggestion, but I teach and demonstrate 4x4s for a living have even tried it rolling slowly, stationary.
I think it's a little more than that, so want to proof the switch is working before moving on to ECU Then actuation motor.

If you had an IID tool, I think you can test the switch operation.
Anyway, to try and answer your question, on an RRS.
You have an igntion supply in via fuse 24 (glovebox) to pin 20 red wire.
This is a common point for the switches and lights. (so if Hi is lit up orange, fuse should be ok)
The switch outputs are on pins 9 (red) & pin 10 (white)

An update on my high low box.
I have unplugged and cleaned connections to the transfere box, which seems to have cleared my solenoid fault  tested switch with IID and getting no activity, does this mean I have o replace the switch panel?
Also been doing battery checks each morning.
Ign off voltage 13.8
Ign on voltage drops to 11.8
Will get battery load tested next week but the drop from off to on seems a little high any ideas?

The whole switch panel can be taken apart.
There are screws in the rear ?
and lots of tabs around the outside.
Go carefully.
I think there are TV remote style membrane type switches in there.
So the PCB needs a clean off with alcohol (on the gold switch points)
and the membrane on the black bits which touch it (need a careful clean - alcohol or washing up liquid).
Voltage look fine. Wouldn't waste any time investigating those.
