2nd Gen Chassis Codes: YF3 • YF4 | Model Years: 2009, 2010, 2011, 2012, 2013, 2014, and 2015
This page provides the complete 2009–2015 Honda Pilot radio wiring diagram for the 2nd generation Pilot (chassis codes YF3 and YF4). Use this guide when replacing the factory head unit or troubleshooting audio in a 2009, 2010, 2011, 2012, 2013, 2014, or 2015 Honda Pilot.
The 2nd generation Pilot received a significant exterior and interior refresh while maintaining the same basic platform. The Touring trim continued offering the factory navigation and rear DVD entertainment system. An updated premium audio system with additional speaker locations was offered on EX-L and Touring trims. The 2012 mid-cycle refresh updated the interior and infotainment interface while retaining the same core audio architecture, meaning the same harness adapters generally apply across the full 2009–2015 model range.

Frequently Asked Questions
Does the 2009–2015 Honda Pilot have a factory amplifier?
EX-L and Touring trims of the 2nd generation Pilot include a factory-amplified audio system. The amplifier is located under the driver’s seat on most 2nd gen configurations. LX and base EX trims use a passive, non-amplified configuration. If your Pilot has the premium audio badge or more than six active speaker locations, it almost certainly has the factory Amplifier and requires an amplifier bypass harness during a head unit replacement.
What wiring harness adapter fits a 2009–2015 Honda Pilot?
For non-navigation 2nd generation Pilot trims, Metra 70-1727 Wire Harness Adapter covers the standard radio connector. Navigation-equipped EX-L and Touring trims require a navigation bypass harness in addition to the standard radio harness. The 2012 refresh did not change the radio connector type, so the same harness adapter applies to both pre- and post-refresh 2nd gen Pilots. Confirm your trim’s navigation and amplifier status before ordering.
What size are the factory speakers in a 2009–2015 Honda Pilot?
The 2nd generation Pilot uses 6 1/2″ Speakers in the front door panels. Rear second-row speaker coverage is provided by B-pillar-mounted speakers. Third-row audio comes from rear side panel speakers. EX-L and Touring trims with premium audio include additional Tweeter locations in the A-pillars. The three-row cabin layout requires more speaker locations than a typical SUV, so confirm the complete speaker inventory for your specific trim before planning an upgrade.
How do I retain the rear DVD system when replacing the front radio in a 2009–2015 Honda Pilot?
The rear DVD entertainment system in the 2nd gen Pilot sends audio to the rear cabin speakers through a circuit partially shared with the front head unit. Use a wiring harness adapter that explicitly maintains the rear entertainment audio path. Avoid cutting the factory connector, as doing so risks severing the Rear Entertainment signal without a clear way to reidentify the affected wires afterward. Consult a wiring diagram specific to your trim before attempting to separate the front and rear audio circuits.
Does the 2009–2015 Honda Pilot have CAN-bus steering wheel controls?
No. The 2nd generation Pilot uses Honda’s resistive steering wheel control system, not a CAN-bus system. A resistive SWC retention interface such as the PAC SWI-RC or iDatalink ADS-MSW in resistive mode is compatible. The transition to CAN-bus SWC in Honda Pilots occurred in the 3rd generation (2016+). If you are installing an Aftermarket Head Unit in a 2009–2015 Pilot, a standard resistive interface is all that is needed for SWC retention.
