INSTALLATION GUIDE
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.
