Threw my voltmeter on the multi-switch stalk and found, to my surprise, that the top left (from drivers seat) orange with red stripe wire carries modulated voltage (between 0.8v to 4.8v) tied to the dimmer switch. BUT it's also tied to the interior lights. So when the door opens and interior lights go on, that light will stay on for a few seconds and then time out. Actually every time you adjust the dimmer switch, it powers up and then goes into a timer mode, UNLESS the headlights are switched on (or, probably, locked with remote). Which all means, I found the wire for constant dimmed 12v power but not dimmed AND switched power 12v power. This dimmed power will go to my independent switch light - when lights are on, dimmed light to match dash (hopefully). Bad side is that every time I open the door they will also slightly illuminate. Better to find the dimmed power from behind the instrument panel but that is a pain - after looking at the diagrams, I think it's a orange with brown stripe wire but not confirmed.
For switched 12v power, I added a circuit on the fuse 32 (radio) 10a circuit. This switched constant 12v will go to my dependent switch light - when ignition is turned to "on" or start, my switch (when toggled) will fully illuminate.
Jut so everyone knows how to wire up new switches for future use.
