Suzuki Indicator Lamp Wiring Diagram - Combination Meter BEAM, OD OFF, 4WD

Wiring diagram showing combination meter indicator lamps wired to the transmission control module, cruise control unit and 4WD switch.

AI caption · Photo 46 of 86

This scanned wiring diagram shows the indicator lamp circuits within the combination meter (instrument cluster) of a Suzuki vehicle. Power comes from two 15A fuses in the fuse box (positions 12 and 18) through W/Bl and B/W wires and connectors E37/G06, E38/G05, G09, and G11 to five indicator lamps: BEAM (high beam), POWER, OD OFF (overdrive off), CRUISE, and 4WD. The BEAM lamp grounds through the dimmer & passing switch via a red (R) wire; the POWER and OD OFF lamps connect via W/G and W/B wires to the Transmission Control Module (automatic transmission); the CRUISE lamp routes through a V/R wire, the E42 ignition switch, and a Gr wire to the cruise control unit; the 4WD lamp connects through O/B wiring, connectors E54/C10 and C08/P01, to the P03 4WD switch, then to ground via black (B) wires at ground points 10 and 9. A legend distinguishes circuit variations: [1] A/T, [2] M/T, [3] IWATA, [4] CAMI (build plant/transmission variants). Readers can learn fuse ratings, wire colors, connector identities and pin numbers, and the switching/ground path for each dash indicator lamp.

Frequently asked questions

What fuses power the combination meter indicator lamps in this diagram?
Two 15A fuses in the fuse box, positions 12 and 18. Fuse 12 feeds a W/Bl wire through connector E37/G06 (pin 13); fuse 18 feeds a B/W wire through connector E38/G05 (pin 8).
Which indicator lamps are shown in the combination meter?
Five lamps: BEAM, POWER, OD OFF, CRUISE, and 4WD.
How does the 4WD indicator lamp circuit work?
The 4WD lamp connects via an O/B (orange/black) wire through connectors G09, G06/E37, E54/C10, and C08/P01 to the P03 4WD switch. When the switch is ON, the circuit completes to ground through black (B) wires at ground points 10 and 9.
What wire color goes to the cruise control unit?
A Gr (gray) wire from pin 20 runs to the cruise control unit; the CRUISE lamp side uses a V/R (violet/red) wire that also routes through the E42 ignition switch.
What do the legend symbols [1], [2], [3], and [4] mean?
[1] = A/T (automatic transmission), [2] = M/T (manual transmission), [3] = IWATA, [4] = CAMI — indicating pin/connector differences by transmission type and build plant.
