Which fuses power the combination meter circuit?

Fuse position 13 (15A), which feeds the lighting switch for illumination, and fuse position 18 (15A), which feeds the combination meter directly on a B/W wire to connector G11 pin 9.

What gauges and components are inside the combination meter?

The illumination lamp (ILL), tachometer, temperature gauge, vehicle speed sensor, and fuel gauge.

What wire color carries the fuel gauge sender signal?

Y/R (yellow/red), running through connectors G02/L02, L18/M07 and M10 pin 2 to the fuel level gauge sender, with the sender grounded via a B (black) wire at ground point 11.

Where does the vehicle speed sensor signal go?

The speed sensor output leaves the combination meter on a Y (yellow) wire and goes to pin 22 of the engine control module.

What do the numbered legend boxes 1-4 mean on this diagram?

They indicate build variants: [1] 2-Door CAMI, [2] 2-Door IWATA and 4-Door, [3] IWATA, [4] CAMI. Connector pin numbers differ depending on the variant.

This document is a scanned wiring diagram for the combination meter (instrument cluster) circuit of a Suzuki vehicle. It shows power feeding from fuse box positions 13 and 15A and 18 (15A) through the lighting switch (OFF/TAIL/HEAD positions, connector E40) and directly to the combination meter connector G11. The combination meter contains the illumination lamp, tachometer, temperature gauge, vehicle speed sensor, and fuel gauge. A legend distinguishes four build variants: [1] 2-Door CAMI, [2] 2-Door IWATA and 4-Door, [3] IWATA, and [4] CAMI, with different connector pin assignments for each. Downstream circuits run through connectors G07 to the illumination controller, G05/E38 to a noise filter and the engine control module (tachometer signal, Br wire), G06/E37 and E54/C10 to the coolant (water) temperature gauge sender (Y/W wire), the vehicle speed sensor output to the ECM (Y wire, pin 22), and G02/L02, L18/M07, and M10 to the fuel level gauge sender (Y/R wire). Wire colors shown include W, B/W, R/Y, R/G, B, Br, Y/W, Y, B/Y, and Y/R, and ground points are numbered 9, 10, and 11. Useful for diagnosing gauge, speed sensor, and cluster illumination faults.
