OK. That is weird.
For sure someone has been it there as evidenced by the non-stock plastic covered spade connectors.
Looking in the WSM on page 65 of the Electrical Section there is a drawing showing that the sidelight microswitch is the top one and the headlight microswitch is the bottom one (when placed in the normal position on the inside). Note the switches are identical and interchangeable, so this could have been changed during a previous repair.
Can you perhaps get in with an ohmmeter or test light to function test the microswitches? Just disconnect the common and one wire at a time from each microswitch to check they work as they should by pulling the light knob in and out.
Am I missing something, or are their three wires connected per switch? The top terminal on the switches is the Normally Closed (NC) terminal. It is normally not used.
Real stretch, but do you have electric pod lifts rather than vacuum? The NC terminal can be used for the pod motors to save a relay, but this is strictly a mod and non-stock.
I will look thru the wiring diagrams to see if I can see these wire colours. Red/White is listed as follows in BS-AU7 1983 Colour Code for Vehicle Wiring, from the British Standards Institution.
Can you see in to the sidelight momentary rocker switch to observe the wire colours on the top two terminals (2 and 3 in the diagram)? Are they with plastic covered spades indicating they have been screwed with? If you can see the wires connected to the sidelight rocker switch, those are the two to connect together to see if the sidelights come on.
Do your headlights work on low and high beam?
Can you locate the two relays for the headlights? Going purely from memory, but on the left inner fender under the hood along with the horn relay. Check the wire colours there.

- a) Sidelamp fuse to right-hand side and rear lamps
- b) Sidelamp fuse to panel light rheostat
- c) Fuse to panel light switch or rheostat
- d) Fuse to fibre optic source
