What circuits are shown on the illumination wiring diagram?

Power runs from the battery through a 15A fuse in the fuse block to the combination (light) switch, then feeds the A/T indicator lamp, heater control panel, illumination control, rear defogger switch, radio (with or without cassette deck), and combination meter (with or without tachometer).

What do the symbols T, WO, RC, and R mean in the diagram?

(T) means with tachometer, (WO) without tachometer, (RC) radio with cassette deck, and (R) radio without cassette deck.

What wire colors are used for the interior and luggage compartment lamp circuit?

Red (R) from the fuse block, LG/B to the left and right door switches, B/W and B to the luggage compartment lamp, and B to body ground (connector 80M).

Which connectors relate to the door switches for the interior lamp?

Connector 77M for the door switch L.H. and connector 76M for the door switch R.H., both on LG/B wires.

What fuse feeds the interior lamp circuit?

A 15A fuse in the fuse block supplies power from the battery in both diagrams.

This scanned service manual page (EL-44, section 'Interior Lamp') contains two wiring diagrams. The first, 'Illumination/Wiring Diagram' (SEL512I), shows power flow from the battery through a 15A fuse in the fuse block to the combination (light) switch, including a switch continuity table for OFF/1ST/2ND positions across terminals 5–12. From the switch, illumination circuits feed the A/T indicator lamp (connector 74M), heater control panel (64M), illumination control (3I), rear defogger switch (7I/14I), radio (15I with cassette deck, 9I without), and combination meter (6I, versions with and without tachometer). A legend defines symbols: (T) with tachometer, (WO) without tachometer, (RC) radio with cassette deck, (R) radio without cassette deck. Wire colors shown include R (red), R/W, G/W, B, and LG/B, with body grounds at connectors 13M/55M. The second diagram, 'Interior and Luggage Compartment Lamp/Wiring Diagram' (SEL513I), traces battery power through a 15A fuse to the interior (room) lamp via connector 56M and the room lamp harness, with LG/B wires to left (77M) and right (76M) door switches, and to the luggage compartment lamp via connector 86M with B/W wiring and body ground at 80M. Connector numbers and harness names (main harness, instrument harness) are labeled throughout.
