Wiring diagram of the radio circuit showing power feeds, the lighting switch and front and rear LH/RH speaker connections.
Part of 1986-1995 Suzuki Samurai Wiring Diagrams
This is a scanned radio/audio system wiring diagram, uploaded to a 1986 Suzuki Samurai gallery. It shows power feeds from the fuse box: fuse position 17 (20A) supplying a white/black (W/B) wire and fuse position 13 (15A) supplying a white (W) wire. The white wire routes through connector E40 pin 10 to the lighting switch (OFF/TAIL/HEAD positions), with a red/yellow (R/Y) illumination wire leaving lighting switch pin 8 and passing through connectors E38/G05 (pin 13) to the radio. The dimmer & passing switch is referenced. Constant/switched power and illumination enter the radio via connector G19 (pins 3, 2, 1 carrying W/B, W, and R/Y). Radio outputs go through connector G18 to the front speakers, LH via G03 (Bl +, B/Bl −) and RH via G23 (W +, W/R −), and through connector G17 and intermediate connectors G02/L02 to the rear speakers, LH via L15 (Lg +, Lg/B −) and RH via L12 (Gr +, Gr/B −). The radio also has a chassis ground. The diagram gives all connector numbers, pin numbers, and wire color codes needed to trace or repair the factory radio circuit.

Frequently asked questions
- What fuses power the radio circuit in this diagram?
- Fuse position 17 rated 20A (feeding a white/black wire) and fuse position 13 rated 15A (feeding a white wire) in the fuse box.
- What are the speaker wire colors?
- Front left: Bl (+) and B/Bl (−) at connector G03. Front right: W (+) and W/R (−) at connector G23. Rear left: Lg (+) and Lg/B (−) at connector L15. Rear right: Gr (+) and Gr/B (−) at connector L12.
- What wire provides the radio illumination signal?
- A red/yellow (R/Y) wire from lighting switch pin 8, passing through connector E38/G05 pin 13 and entering the radio at connector G19 pin 1.
- Which connectors are between the radio and the rear speakers?
- Connector G17 at the radio (Lg, Lg/B, Gr, Gr/B wires) and intermediate connectors G02/L02 (pins 2, 10, 3, 11) before reaching L15 (rear LH) and L12 (rear RH).
- How is the radio grounded?
- The radio has a direct chassis ground shown by a ground symbol on one of its output-side wires.
