What fuse powers the horn circuit in this diagram?

Fuse position 14 in the fuse box, rated at 15A, supplies the horn circuit via a green (G) wire.

What are the wire colors in the horn circuit?

Green (G) from the fuse box to the relay, Blue/Green (Bl/G) from relay pin 3 to the horn switch, Green/Black (G/B) from relay pin 4 to both horns, and Black (B) from the horns to ground.

What connector is the horn relay on?

The horn relay uses connector E58, with pins 1 and 2 receiving power, pin 3 going to the horn switch, and pin 4 feeding the horns.

What connectors are used for the left and right horns?

The left horn (LH) uses connectors E01 (pin 1, input) and E02 (pin 1, output); the right horn (RH) uses E05 (pin 1) and E06 (pin 1).

How does the horn switch complete the circuit?

The horn switch (connector E40, pin 4) receives the Blue/Green wire from relay pin 3 and switches it to ground, energizing the relay coil so the relay powers the horns.

This document is a wiring diagram for the horn circuit, uploaded as part of a set of Suzuki Samurai reference scans. It shows power originating at the fuse box, fuse position 14 rated at 15A, feeding a green (G) wire that splits to supply both terminals 1 and 2 of the horn relay (connector E58). Relay terminal 3 exits on a Blue/Green (Bl/G) wire to the horn switch (connector E40, pin 4), which completes the relay coil circuit to ground when pressed. Relay terminal 4 outputs on a Green/Black (G/B) wire that splits to feed both the left horn (connectors E01 pin 1 in, E02 pin 1 out) and the right horn (connectors E05 pin 1 in, E06 pin 1 out). Both horns return on Black (B) wires that join and terminate at a chassis ground marked with the symbol ❶. From this diagram a reader can identify the fuse (14, 15A), relay connector (E58), horn switch connector (E40), horn connectors (E01/E02 LH, E05/E06 RH), and all wire colors used in the horn circuit for troubleshooting a non-working horn.
