Otto, this pic may help. Here's Dan's photo marked in red on the bus bar from the tail light terminal to the instrument light rheostat. The furthest forward (right) on your photo is power coming in from the Ammeter, the next one is Park Lights, the center is Tail Lights, and the next is Headlights (via the dimmer switch).
I'm not seeing the bus bar on your switch photo going to the instrument light rheostat that I highlighted in red. If that's missing, there won't be any power going to the rheostat, and of course nothing coming out of it to the instrument lights. If that has broken off it would explain why your instrument panel lights don't work. If you connect the wire going to them to the Park Light terminal, they'll be on full brightness anytime you pull the light switch out one notch.
