Installation of Horn Spring Contact (Optional)
- Install Horn Spring Contact into the round opening located at the five o'clock position, down and to the right of the center of the steering shaft. Note: Horn Spring Contact is "keyed".
- When the steering wheel wires were disconnected, the closest connector to the driver will be spliced to the Horn Spring Contact. This connector has two wires, a brown with red strip and a solid brown one. Using a "wire splice in connector" splice the Horn Spring Contact to the brown with red strip wire.
