Right.
I am picturing these as 3 separate Functional BLocks.
Since I have nothing I need to be ON without the Key on I have no fuse or wires to the RED wire area to the upper right.
My picture may be confusing as there are 2 RED wires. One with a White pastic end in the upper right corner and no fuses goes to the BAT.
The other RED wire with the BLACK end is from the Heater to get power off the Accessories PINK strip with the 4 fuse locations.
The Pink Area along the bottom should get power from the PINK wire from the Ignition switch. They all have separate fuses (not really fused together).
The GRAY pulls power from the light switch and I would think is variable as you turn the light switch clockwise and make it dimmer or brighter. The GRAY wire area with the 4 tabs Upper left of my pictures, has the place for a fuse and a single tab at the bottom of it. What is the purpose of that fuse? Seems to be for some other accessory or something but it would be variable power as it gets it's power from the GRAY wire that shares the tabs on the light switch that go to the Panel lights which are variable intensity?
I was thinking that the Fuse on the light switch was for something else (like some accessory) as the Switch itself looks like it has a Breaker setup in it that would disconnect and trip when it got too Hot from a short for the head lights and then reset when it cooled down.
