K12 Reverse Light Switch Pin Out

I have a 2005 K12 with non functioning reverse lights
Tried to get some voltage at the connector in the back with the multimeter to no avail, so now trying the switch on the gearbox.

I can only see the one swich but it had 3 pins. Does anyone know what pins need to be bridged to mimic the switch being on for reverse? At least if i can get it to work by bridging pins i know its the switch without having to remove it from the box and fill oil.
Is there any other components the signal goes through before the reverse lights fuses ecu etc that can be inspected?

Does your rear wiper automatically come on when the front ones are on and you select reverse? If so then there is nothing wrong with the switch.....
