Nurdge. If it's the same black/blue line documented in the European wiring
diagram open across my knees, I'm not in the slightest surprised!
It creeps into existence, via fuse 12, in track 52. It leaps off down-track
to 48, goes brown/black, and hops off to track 15 to power relay socket 8.
As the original black/blue, it also flicks back on itself to tracks 49, 50 and
51 to power the indicator lamp for the rear differential lock, the lamp for the
centre differential lock, and the "full load" enrichment valve. Dropping of
the original track 52, it powers the reversing lights.
Tapped off from the base of fuse 12, it passes via line "b" into track 90.
This splits back to 73, which merges up to 72, which folds both over (to T2)
and under (to J124 - the rear lamp control unit) and the headlamp switch
backlight.
Anyway, the other split of track 90 touches pin 3 of the warning lights, then
bounces to pin 15a on the same switch, which provides the backlight, and
continues to the reversing light switch.

Just about everything, old son. Check fuse 12.
