Horn

  1. Ignition OFF, disconnect the harness connector at the horn.
  2. Install a 10A fused jumper wire between the control terminal B and 12 volts.
  3. Install a jumper wire between the ground terminal A and ground. Verify the horn emits a clear and even tone.
    • If the sound emitted is not clear and even, replace the horn.
