Question No power to Octopus console light cable

1983 300D Turbo/Auto

-Cluster lights work
-Hazard switch light works
-Cigar lighter has power
-Window switches work
-Center console buttons work (Antenna, Sunroof, Courtesy light)
-Map light works
-All fuses work (12v probe test)

I've tried replacing all 5 bulbs on the octopus cable and nothing powers on.

Method:
-Ignition key ACC Position/ or engine Running
-Headlights On/Parking lights on

I've also used a 12v probe light to test the circuits above. The only one not receiving power is the Octopus. I cant trace the cable far enough as it goes Up towards the Dash/Behind center vents.


Any ideas?

Maybe a loose wire at the Dimming Rheostat? The Instrument cluster lights are tied together there.
