Drama is that on a vp when you turn the lightswitch on it supplies a 12v+ on the brown wire for instrument lights and park lamps and a negative on the white/black wire for the headlights.
On a vs it supplies a negative on the white/blue wire for the headlight and also a negative on the blue wire.You need to make that blue wire supply a negative to a relay to switch a positive to the brown wire to get the park and instrument lights to work. After you do this you can also get the domelight function to work on the headlight switch ....you need to unconnect the purple wire to the orange/white wire and join another wire to where you joined the white /green and white wire (as per my directions in post 16 above) and run it over to the r/h side to join with the purple wire and then get the spare black wire in your bottom picture and join it to the other black wires already joined by the red connectors.
To get the dimmer to work is a fair bit more difficult but I never use it anyway.
Getting back to the lefthand old switchblock functions I have a way of putting the dome delay in the circuit by using part of the old circuitboard and also a way of installing the stalk mounted wiper switch so all the wiper functions work including intermittent.See this diagram in post 16 how I got it to work
