Fiber Optic Cable: The factory fiber optic cable needs to be removed from the factory radio and connected to the interface.
The diagram illustrates the AXDIS-P072 interface unit with 6-pin and 16-pin connectors. The BLK-AXDIS-PO72 harness connects to these, then splits into a vehicle connector and radio connections. The radio connections are color-coded wires for ground, battery, accessory power, brake, illumination, amplifier control, reverse, speed, antenna, and SWC. A separate fiber optic connection is also shown.

Dipswitch Operation: Press dipswitch in to the down position to turn ON.
The diagram shows a series of five dipswitches labeled 1 through 5. An example for Pioneer 1 is indicated, showing switches 4 and 5 in the ON (down) position, and switches 1, 2, and 3 in the OFF (up) position.
Installing the AXDIS-PO72 Interface
With the key in the off position:
- Connect the male 3.5mm jack to the steering wheel control port on the radio.
- Ensure that the dipswitches are set to the desired radio type. Refer to SWC Chart on Page 4.
- Connect the AXDIS-PO72 harness to the AXDIS-PO72 interface.
- Remove the dust cover from the optic port on the AXDIS-PO72 interface.
- Connect the factory fiber optic cable to the AXDIS-PO72 interface.
- Connect the AXDIS-PO72 harness to the wiring harness in the vehicle.
- Turn on the ignition and test all features.
The front view of the interface shows the 16-pin connector, the 6-pin connector, and the dipswitch detail labeled N, O, K, E, and numbered 1 through 5.
Note: For Dipswitch Settings for your Radio Type, refer to SWC Chart on Page 4.
Installing the Fiber Optic Cable
Removal of the original fiber optic connection is required to adapt to the Media Oriented System Transport (MOST) interface.
- Seat the AXDIS-PO72 amplifier interface in the black connector housing provided with this kit and snap the housing in place. (Figure A)
- From the original Fiber Optic Connector: Using a pick tool, carefully pull the tab towards the outside edge for the connector housing. Gently remove the gray fiber optic insert from the connector. (Figure B)
- From the MOST Interface: Push the tab toward the gray dust cover and, using a needle nose plier, remove the gray dust cover. Replace the gray connector with the factory fiber optic cables into the MOST interface's black connector housing. (Figure C)
Figure A shows the AXDIS-PO72 interface being seated into a black connector housing. Figure B shows a pick tool being used to release a tab on the original fiber optic connector to remove the gray insert. Figure C shows a needle nose plier being used to remove a gray dust cover from the MOST interface connector.
Installation Tips
- In these types of vehicles, there could be other MOST 25 modules that need to be bypassed in order for the audio to function correctly. It is recommended that you order AXFO-LOOP.
Steering Wheel Control Configuration
The steering wheel controls are labeled A, B, C, D, and E. Their functions are as follows: A. Volume Up/Volume Down (Scroll) Mute (Push) B. Source C. Phone Pick Up D. Track Up/Track Down (Scroll) Band (Push) E. Phone Hang Up
