INSTALLATION GUIDE See wiring diagram on Pg.
4 for more information
Before installing the interface, the factory stereo must be removed and disconnected. To do this, please consult
the vehicle owner’s manual/handbook or contact a fitting professional.
A stereo connection (patch) lead is also required for the installation of this interface (supplied separately).
Please ensure that you have the correct lead before proceeding. For universal patch leads, prepare the wiring
loops in accordance with the instruction manual supplied with the product before installation.
1. Connect the 12 Pin connector from the stereo connection (patch) lead to the interface box
2. Connect the opposite end of the stereo connection (patch) lead to the steering wheel control input on
the back of the aftermarket stereo
NOTE: This may be a 3.5mm jack connector or a wired input depending on the brand of aftermarket stereo being fitted. Please consult the
aftermarket stereo installation manual for further information on where to make the connection
!
IMPORTANT: THIS STEP MUST BE COMPLETED BEFORE CONNECTING POWER TO THE INTERFACE.
FAILURE TO DO SO MAY RESULT IN A LACK OF FUNCTIONALITY AND THE NEED TO REINSTALL THE
PRODUCT
3. Connect the 14 Pin connector from the supplied wiring loom to the interface box
4. Connect the power/speaker ISO connector to the power/speaker ISO connector from the
aftermarket stereo.
NOTE: For aftermarket stereos which do not have an ISO connector, please see “Wiring Key” on Pg.2 for information on which wires to
connect. Some interfaces may also have additional ‘flying’ wires which can be connected to the vehicle to support various features
ie. parking brake trigger, reverse gear and speed pulse. Details of these can be found under ‘Additional Connections’.
5. Connect the vehicle specific connectors on the supplied harness to the vehicle specific connectors from
the vehicle. Please refer to wiring diagram on Pg.4, or cover photo on Pg.1 for more information on the
connector style of this interface.
6. Connect the USB connector to the back of the aftermarket stereo to retain the vehicle’s USB input (if
vehicle is equipped).
7. Connect the red/white RCA connectors to the back of the aftermarket head unit to retain the vehicle’s
AUX input (if equipped).
8. Test stereo and steering wheel control functionality for correct operation before reassembling the
vehicle dashboard. If steering wheel control functions are unresponsive, please uninstall the interface and
wiring and reinstall carefully in accordance with the above steps.
