Wiring diagram of the 4WD circuit showing the 4WD switch, combination meter indicators and transmission control module connections.
Part of 1986-1995 Suzuki Samurai Wiring Diagrams
This scanned wiring diagram page shows the circuit for the Transmission Control Module (A/T) indicator and 4WD switch wiring on a Suzuki vehicle. Power originates at fuse position 18 (15 amp) in the fuse box, feeding a Black/White (B/W) wire through connectors E38/G05 (pin 8) and G11 (pin 9) to the combination meter, which contains the 4WD indicator lamp and P/N indicator lamp. From the meter, an Orange/Black (O/B) wire runs through connectors G09, G06/E37 (pin 10), E54/C10, C08/P01, and P03 to the 4WD switch (OFF/ON), which grounds through Black (B) wires to chassis grounds 9 and 10. White/Green (W/G) and White/Black (W/B) wires run from the meter through G05/E38 to pins 8 and 20 of the Transmission Control Module (A/T) at connector E43. TCM outputs include pin 7 (Blue wire, Bl) to connector E32/F01, pin 18 (Blue/Orange, Bl/O) to the Monitor Connector (Engine, RWAL & A/T), and pin 24 (Black/Blue, B/Bl) to ground point 3. A legend distinguishes connector pin assignments between IWATA and CAMI production plants. The page is useful for tracing 4WD indicator, P/N indicator, and automatic transmission control module wiring.

Frequently asked questions
- What fuse powers the combination meter 4WD and P/N indicator circuit in this diagram?
- Fuse position 18 in the fuse box, rated 15A, feeding a Black/White (B/W) wire to the combination meter.
- Which Transmission Control Module (A/T) connector pins are shown?
- Connector E43 pins 8 and 20 (inputs via W/G and W/B wires from the combination meter) and pins 7 (Bl to E32/F01), 18 (Bl/O to the monitor connector), and 24 (B/Bl to ground).
- What wire color connects the 4WD switch to the combination meter?
- An Orange/Black (O/B) wire runs from the combination meter through connectors G09, G06/E37, E54/C10, C08/P01, and P03 to the 4WD switch, which grounds through Black (B) wires.
- What do the [1] and [2] symbols in the diagram mean?
- They indicate different connector pin numbers by production plant: [1] = IWATA, [2] = CAMI.
- Where does TCM pin 18 (Bl/O wire) go?
- To the Monitor Connector for Engine, RWAL & A/T diagnostics.
