Nissan Maxima A35 (2009–2014) — Factory Head Unit Type 2 Wiring Guide

Step 1 — Remove the Factory Head Unit

  • Use a plastic trim tool to carefully open the dash bezel.

  • Unscrew the factory screws and slide out the head unit.

  • Disconnect all plugs from the factory harness.


Step 2 — Connect to the Factory Harness

Type 2 uses a slightly different harness layout. Match each connector according to the diagram:

  • Main Power Harness → connects to the car’s power and speaker wires.

  • AC/Climate Control Cable → keeps A/C display and control buttons working.

  • CAN/Protocol Plug → required for steering wheel controls and data communication.

  • AUX Cable → routes sound into the Bose amplifier.

  • Reverse Trigger Wire → connects to the car’s reverse light for backup camera activation.
