Installation
12-pin Harness
- Connect the Black wire to chassis ground.
- Connect the Red wire to the accessory power.
- Locate the steering wheel control wire(s) in the vehicle's harness as noted in the ASWC-1 vehicle-specific document. Connect this wire(s) to the ASWC-1.
Note: Axxess recommends soldering wires for the best connection. Tapping style connectors are not recommended.
3.5mm Jack
For the radios listed below: Connect the female 3.5mm connector with stripped leads to the male 3.5mm SWC jack from the ASWC-1 harness. Tape off and disregard any remaining wires.
- Eclipse: Connect the steering wheel control wire (normally Brown) to the Brown/White wire from the connector. Connect the remaining steering wheel control wire (normally Brown/White) to the Brown wire from the connector.
- Metra OE: Connect the steering wheel control Key 1 wire (Gray) to the Brown wire.
- Kenwood or select JVC with a steering wheel control wire: Connect the Blue/Yellow wire to the Brown wire. Note: If the Kenwood radio auto-detects as a JVC, manually set the radio type to Kenwood. See instructions under 'Changing Radio Type'.
- XITE: Connect the steering wheel control SWC-2 wire from the radio to the Brown wire.
- Parrot Asteroid Smart or Tablet: Connect the 3.5mm jack to the AX-SWC-PARROT (sold separately). Then connect the 4-pin connector from the AX-SWC-PARROT to the radio. Note: The radio must be updated to rev. 2.1.4 or higher software.
- Universal "2 or 3 wire" radio: Connect the steering wheel control wire (Key-A or SWC-1) to the Brown wire from the connector. Connect the remaining steering wheel control wire (Key-B or SWC-2) to the Brown/White wire from the connector. If the radio has a third wire for ground, disregard it.
- For all other radios: Connect the 3.5mm jack from the ASWC-1 harness to the jack on the radio designated for an external steering wheel control interface. Refer to the aftermarket radio's manual if unsure.
Note: After programming the interface to the vehicle, refer to the radio's manual for assigning SWC buttons. Contact the radio manufacturer for more information.
