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 feature addresses 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
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 dipswitches. 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.

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 lead to the steering wheel remote input
on the rear side of the aftermarket stereo. Connection methods vary based on
the stereo brand, utilising either a 3.5mm jack connector SWC IR wire or wired
inputs KEY1 and KEY2. Note: For specific connection guidance, refer to your
aftermarket stereo’s installation manual if not clearly labelled on the stereo
harness.
3. Connect the 6-pin male connector to the grey vehicle-specific connector
(pictured). This connector will either be located at the bottom of the dash,
loose, or connected via the cup holder of the vehicle. Do not connect to the
orange variant. Note: If the vehicle has a Qi charger, disconnect the charger
connector and use the male and female connectors between them to act as a
T-harness.
4. Route the pin end of the speed/reverse wires from the main dash aperture
through and down towards the fuse panel. Leave the bare-ended wires in the
dashboard aperture for use on the new head unit.
5. Disconnect both the green and black connectors located at the fuse box.
6. Take the green connector and remove the blue/white wire from pin location
17 from the back of the housing. Then, take the orange reverse wire from the
supplied harness and plug it into the original place. Note: When removing the
blue/white wire from the original location, try to ensure that the retaining
clip does not get damaged. If it bends, gently bend it back into shape for
reuse.
7. Place the original blue/white wire from the vehicle into one of the 2-pin
housings. Once done, insert this 2-pin assembly into the blue housing on the
supplied harness. Note: The location of the blue/white wire must match the
location seen from behind the blue connector.
8. Insert the green speed wire into pin location 22 on the back of the black
connector housing. Note: Before making any connections, ensure that the
signals are present, as pin positions may vary depending on the vehicle.
9. Connect the power/speaker ISO connector to the power/speaker ISO connector
at the rear of the aftermarket stereo. Note: For aftermarket stereos without
an ISO connector, refer to the “Wiring Key” on Pg. 2 for information on which
wires to connect. Some interfaces may also have additional flying’ wires that can be connected to the vehicle to support various features, such as parking brake trigger, reverse gear, and speed pulse. Details of these can be found under
Additional Connections’.
10. Connect the female Mini ISO connector on the harness to the male
equivalent connectors from the vehicle. Test the stereo and steering wheel
control functionality for correct operation before reassembling the vehicle
dashboard. If the steering wheel control functions are unresponsive, uninstall
the interface and wiring, then reinstall carefully according to the above
steps.
11. 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.

The provided diagram, while meticulously researched, serves as an example only. Actual steering wheel control configurations may vary dependant on 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 own bespoke
configuration. Button configuration can be done by PC, MAC and smart phone via
the USB port.
Button Remapping instructions can be found in a separate guide on our website.
