Audio Interface Harness Adapter
Installation Guide (for BOSE equipped 2007-08 G35 Sedan and 08-15 G37, Q40, Q60)
1. Ensure the car is OFF and locate the BOSE Amp in the trunk (see diagrams below).
2. Use a medium sized flathead screwdriver to press in the latching clip & carefully disconnect the
connectors from the Bose Amp and/or Bose Sub Amp that will attach to the harness adapter.
3. Plug the adapter into the corresponding connectors as appropriate. Also make any connections
between the adapter itself, if applicable.
4. Refer to the labeling on the harness adapter to connect your audio equipment.
The Bose radio outputs low-level differential balanced signals (that go through the specifically
designed RCA connections of the harness adapter). Therefore, we recommend audio equipment that
has differential inputs, or RCA inputs capable of accepting preamp and speaker-level signals.
Otherwise, you may need to use an appropriate Line Output Converter to avoid sound quality issues.
5. Speaker Wiring (if your adapter has it) is labeled with a speaker number, in reference to the diagrams
below. Speaker wiring goes to the Output of your amplifier(s).
Note: Gray or Red wire connections are + (Positive). Black wire connections are -(Negative).

6. After making the connections you want to your audio equipment, be sure to properly secure any
remaining/unused connections of the adapter to avoid any shorts or damage.
7. Once all your connections have been made and everything is secure, you can turn the car on to test
everything out. Ensure everything looks and sounds ok.
8. Adjust your equipment settings as necessary, and that’s all there is to it!
Enjoy Your New Upgrade!
