CONNECTIONS
IMPORTANT INFORMATION
Kenwood/JVC : Some Kenwood/JVC radios have 2 steering control inputs. A
3.5mm socket (Remote IN) and Blue with Yellow trace wire. To send directly
translated codes to your Kenwood/JVC radio, configure the patch lead-up as
Kenwood or JVC outlined in the configuration assignments and connect the Brown
patch lead wire to the Blue with Yellow trace wire coming from your
Kenwood/JVC harness, Disregard the 3.5mm jack it will not be used. If you
would like to be able to program and re-map your steering controls configure
the patch lead as Sony/LG/Pioneer
and plug the 3.5mm Jack into the Remote IN of the Kenwood/JVC, Disregard the
brown wire.
Pioneer : Some Pioneer models require the steering controls to be enabled in the pioneer radio as they will default OFF. These steering control settings are located in the system settings of the radio can only be accessed whilst the unit is in standby mode and the park-brake wire is connected (if applicable) Please refer to your Pioneer manual for exact methods for enabling steering controls.
Sony: Newer Sony radios may give you incorrect SWC button presses after installing a control harness. This is due to a slight change in input codes on the newer Sony radios. To resolve this please do the following steps:
- Remove the Steering control harness from the vehicle.
- Remove the plastic casing from the black steering control box.
- Locate the very small dipswitch selector on the board
- Turn dipswitch 4 OFF.
- Re-assemble and test.
Some Sony radios default steering controls off. If you are receiving no steering control functions at all please refer to your Sony manual on how to enable steering controls. General: Please ensure all connections to your aftermarket head unit (including patch lead modification) are completed before power is provided to the harness. Some of our control harnesses work by translating the vehicle’s CANBUS data and can only start this process on ignition. If you find that you are not getting any response from your steering controls on the accessory (single key click) please re-test on ignition.
Note : The steering controls must be working in the vehicle previously to work with our control harnesses. They will not fix a previous underlying problem.
