What circuit does this wiring diagram cover?

Instrument illumination — the dash lighting circuit including radio, clock, ashtray, A/C-heater function selector, and instrument cluster illumination.

Where does the instrument illumination circuit get its power?

From a HOT AT ALL TIMES feed through the fuse panel (referenced to page 20), then through the main light switch and back through the fuse panel to the lamps.

What wire color feeds the illumination lamps?

Light blue with red stripe (LB/R) wiring feeds the illumination lamps; grounds are shown as black (BK) dashed lines.

Where can grounding information for this circuit be found?

The diagram notes 'SEE GROUNDS PAGE 2' at the bottom of the ground runs.

This is a photographed page (page 65) from a Ford electrical/vacuum troubleshooting-style wiring manual, titled "Instrument Illumination." The schematic traces the instrument panel dimmer/illumination circuit: power comes from a HOT AT ALL TIMES feed through the fuse panel (referenced to page 20) into the main light switch, then out through another fuse panel reference (circled 24) on light blue/red (LB/R) wiring to the illumination lamps. Illuminated components shown on the circuit include the radio illumination, clock illumination, ashtray illumination, A/C-heater function selector illumination, and the instrument cluster illumination (drawn with bulb symbols). Black (BK) dashed ground wiring collects at the bottom with a note to see the grounds diagram on page 2. Connector references such as C260, C2011 and C702 appear at component junctions, and an inset table in the upper left provides a connector terminal/wire-color legend, though its fine print is not readable in this photo. A reader can learn the general power flow, which lamps share the dimmer circuit, key wire colors (LB/R feed, BK ground), and cross-references to the fuse panel and grounds pages, but small circuit numbers and pin details are mostly illegible due to image quality.
