ASSEMBLY INSTRUCTIONS: Disassembly and reassembly of the rotating ring equipped with the steering angle sensor must be done with the wheels straight in alignment with the vehicle and the steering wheel in neutral position. The rotating ring is delivered in the middle position and locked by a plastic pin. This pin must be broken when mounting on the steering wheel hub, which releases the spring. The pin must not be broken before assembly otherwise the spring will engage and will distort the operation of the sensor. No warranty will be taken into account if the item is damaged following an assembly error.
