DIPSWITCH 5 & 6
Dipswitch 5 & 6 are reserved for vehicle-specific configuration.

KEY1 and KEY2 KEY1 and KEY2 are specifically tailored for analog learning mode-style radios. Our SWC module is designed with a resistor chain that precisely matches the required resistance for seamless compatibility with this type of head unit.
KEY1 and KEY2 EXTEND This mode extends every button press to 2 seconds during the learning process. However, with rolly wheel-designed steering wheel buttons, holding for 2 seconds isn’t feasible. Our KEY1 and KEY2 extend features to address this by automatically prolonging each press, simplifying head unit programming even in such scenarios. Extend mode is not intended for normal use, it is only used in the teaching process.
ANALOG SINGLE WIRE and ANALOG SINGLE WIRE EXTEND This function operates similarly to KEY1 and KEY2 but transmits all unique values through the IR SWC single wire. This is crucial for compatibility with learning-style head units featuring only one learning input wire. To ensure compatibility, we’ve incorporated this feature into our steering wheel control interface, ensuring seamless operation across various head unit setups.

The Analog Extend mode functions identically to its counterpart within the KEY1 and KEY2 system but transmits through a single wire.

CONNECTION GUIDE

BEFORE INSTALLATION
Before 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

  1. Take the interface, then connect the 16-PIN head unit connection lead and the 18-PIN steering wheel harness connectors to their respective ports.
  2. 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.
  3. 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.
  4. Connect the vehicle-specific connectors from the interface harness to the corresponding connectors on the vehicle harness.
  5. Connect the flying wires on the harness to the rear of the stereo (iifapplicable).
  6. Connect the antenna adapter to the vehicle’s existing connection at the rear of the aftermarket stereo.
  7. 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)
  8. When installing a DAB antenna, ensure to connect the DAB aerial connector to the rear of the new stereo.
  9. 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.

  • H Hang Up (Long Press)
    The provided diagram, while meticulously researched, serves as an example only. Actual steering wheel control configurations may vary dedependingn each vehicle.

BUTTON REMAPPING

  • The steering wheel buttons listed offer the flexibility of being re-configured or assigned dual functions. The availability of these buttons depends on the specific vehicle to which the interface is being installed and if the aftermarket radio supports them.
  • In addition to button remapping, we offer the option to assign dual functions to each button on the steering wheel. This means that every button can be programmed to execute both a short press command and a long press command.
  • You can also add your bespoke configuration. Button configuration can be done by PC, MAC, andsmartphonee via the USB port.
  • Button Remapping instructions can be found in a separate guide on our website.
