Right rear light not working

[Phid]

Right rear light not working, number plate lights are ok. Left rear and both front lights ok. Power to fuse ok. Fuse 23 ok. Bulb ok. Indicators ok. No 12v supply at the rear light unit terminal.

So I assume wiring between fuse/switch ? Or bad connection at terminal - although it looks ok.

I read about a rear light check relay in the circuit. Any idea where this is on a Touring?

Sorted this. Poor connection at the switch.
