Connection Guide Before Installation

• Prior to installing the interface, it is essential to remove and disconnect the factory stereo.
• For guidance on this process, please refer to the vehicle owner’s manual/handbook or seek assistance from a professional.

Setting The Dipswitches

• This interface includes a set of dip switches.
• Consult the dipswitch selection guide to select the appropriate configuration.
• To activate a dipswitch, press it downward into the ‘ON’ position.
• Refer to the diagram for an example of the ‘KENWOOD1’ dipswitch configuration.

Installation

• Take the interface, then connect the 16-PIN head unit connection lead and the 18-PIN steering wheel harness connectors to their respective ports.
• Connect the head unit connection to the steering wheel remote input on the rear side of the aftermarket stereo. Connection methods vary based on the stereo brand, utilizing either a 3.5mm jack connector SWC IR wire or wired inputs KEY1 and KEY2. For specific connection guidance, refer to your aftermarket stereo’s installation manual if not clearly labeled on the stereo harness.
• Connect the power/speaker ISO connector from the interface to the corresponding power/speaker ISO connection on the aftermarket stereo. For aftermarket stereos lacking an ISO connector, refer to the “Wiring Key” on Page 2 for guidance on connecting wires. Certain interfaces may also include extra “flying” wires for additional functionalities such as parking brake trigger, reverse gear, and speed pulse. Further information on these wires is available in the “Flying Wire Wiring Key” section.
• Connect the vehicle-specific connectors from the interface harness to the corresponding connectors on the vehicle harness.
• Connect the flying wires on the harness to the rear of the stereo (iff applicable).
• Connect the antenna adapter to the vehicle’s existing connection at the rear of the aftermarket stereo.
• When installing an aftermarket reverse camera, connect the yellow RCA from the harness to the yellow RCA of the aftermarket camera. (If supported by the interface and vehicle)
• When installing a DAB antenna, ensure to connect the DAB aerial connector to the rear of the new stereo.
• After connecting all wires (along with any additional accessories), it’s crucial to thoroughly test the stereo and steering wheel controls before reassembling the dashboard. If steering wheel controls are unresponsive, inspect connections and check dipswitch settings. Repeat the connection process if necessary, following the outlined steps.
