STEERING WHEEL CONTROL SETTINGS:
Note: Identify Alpine SWC learning radios by checking for three SWC cables and a SWC learn menu, instead of a 3.5mm SWC input.
If Interface has one SWR-100 Cable included If Interface has two SWR Cables included
1 - Find the included SWC adapter cable.
1 - Identify appropriate SWC adapter cable.
Do not use cable with Blue / Yellow wire.


2 - Prepare the SWC Cable: Cut the SWC cable. You will find a red wire, a white wire, and a ground (shield) wire inside.


3 - Adjust the Module Settings: Set the module to the Pioneer dip switch setting. This configures the module to communicate correctly with the Alpine radio.
| DIP: | 1 | 2 | 3 | 4 | |
| On Alpine iLX series radios use Pioneer settings | OFF | OFF | ON | ON | |

4 - Configure the Alpine Radio: On your Alpine radio, select the setting that includes an adapter for SWC. This ensures the radio will recognize the steering wheel controls.



Select the setting "With Adapter" Select "SWC Adapter"
5 - Connect the Wires: Connect both the SWC1 and SWC2 wires from aftermarket radio to the red wire from our SWC cable. Connect the SWC ground wire to the shield (ground) wire of our SWC cable. These steps should enable the steering wheel controls on your Alpine iLX series radio.


- Program the SWC: Navigate to the SWC settings on your Alpine radio to assign and test each control function.
