What fuses power the Suzuki Samurai headlights in this diagram?

Fuse positions 12 and 11 in the fuse box, each rated 15A — one feeds the left headlight (W/Bl wire) and one the right headlight (W/R wire).

What wire colors are used in the headlamp circuit?

White/Blue (W/Bl) and White/Red (W/R) feed the headlights from the fuses; Red (R) and Red/White (R/W) run from the headlights to the dimmer/passing switch; Black (B) wires go to grounds 10 and 9.

Which connectors serve the headlights?

The left headlight uses connector E29 (pin 3 feed, pins 1 and 2 outputs) and the right headlight uses connector E03 (pin 3 feed, pins 1 and 2).

What does the dimmer & passing switch connect to?

It receives R and R/W wires from the headlights at connector E40 (pins 11 and 20), has LO/HI/PASS positions, and grounds through Black wires to ground points 10 and 9.

What do the [1] and [2] symbols in the legend mean?

The legend states [1] = IWATA and [2] = CAMI, marking alternate connector pin assignments depending on the build/plant.

This is one page of a scanned factory-style wiring diagram, uploaded to a 1986 Suzuki Samurai gallery, showing the headlamp circuit. Power comes from two 15A fuses (positions 12 and 11) in the fuse box, feeding White/Blue and White/Red wires to the left headlight (connector E29, pin 3) and right headlight (connector E03, pin 3). A White/Blue branch also feeds the combination meter's high-beam (BEAM) indicator through connectors G06/E37 and G09. Return wires from the headlights — Red (low beam) and Red/White (high beam) — route to the Dimmer & Passing switch (connector E40, pins 11 and 20), which selects LO/HI/PASS. The adjacent Lighting Switch (OFF/TAIL/HEAD positions) connects to the fuse box and to the shift illumination lamp. The switch output grounds through Black wires to ground points 10 and 9. A small legend distinguishes variants: [1] IWATA and [2] CAMI (assembly plant designations), indicating alternate connector pin numbers depending on build. Readers can learn fuse ratings, wire colors (W/Bl, W/R, R, R/W, B), connector identifiers (E29, E03, E40, G06, E37, G09), and the overall current path for the headlamp system.
