1990 200TDI. On to my next problem, Still more to come

After trawling through loads of photos and posts on internet I think ive finally found the difflok switch, will find out tomorow in the daylight.Think I should be able to feel / reach for it from under the drivers floor panel.
Anyway fom the photos cant make out where the wires lead too some seem to just go straight into the side of transfer box, reason Im asking is trying to get the light on the dash to work, as its never worked yet.
Do the wires lead anywhere back up to the top or do they loop back to near where they come from????
Thanks

If it helps at all there's a multi plug behind the airbox that connects the engine loom to the bulkhead, I found on mine the plug had either corroded or been strained and the pin had half slipped out. Looked connected but wasn't making contact

that wire should come out through bulk head with other wires ,check at the connectors near clutch pedal box, feed from dash light through connector to switch is black/blue and earth just black as all earths

OK Mate will have a look.
Is there an easy way of undoing the 17 Mm nut seems hard to get a spanner in there.

Does the switch just unscrew out from the top of the 17m nut?
