Yeah the thick red cable is permanent Live to the switch.
Out from here are ACC (Blue/Yellow) from the first position on the switch, plus IG1 (White/Black) and IG2 (Blue/Red) on position 2 of the switch.
So, to verify that the switch itself isn't at fault, you can bridge the Red to these, and stuff should light up...
After that, you'll be looking at fuses in both fuse boxes, and just tracing these wires through as far as you can until you find something untoward...
I'd still say...
