This page contains the complete 2006–2014 Honda Ridgeline radio wiring diagram for the 1st generation Ridgeline (chassis codes YK1 and YK2). Use this guide when installing an aftermarket head unit or troubleshooting your factory stereo in a 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, or 2014 Honda Ridgeline.
The 1st generation Ridgeline was Honda’s unibody pickup truck debut, sharing its platform with the Pilot and Odyssey. RTL and RTX trims introduced a factory navigation system integrated into a double-DIN head unit, which significantly affects the replacement process. The Ridgeline’s in-bed trunk — one of its signature features — is unrelated to the audio system but worth knowing about when routing subwoofer or amplifier cables through the cabin. Higher trims included a factory-amplified audio system with additional speaker locations in the extended cab area. The Ridgeline was discontinued after 2014 and relaunched as a fully redesigned 2nd generation in 2017.

Frequently Asked Questions
What wiring harness adapter fits a 2006–2014 Honda Ridgeline?
For non-navigation 1st generation Ridgeline trims (RT and RTS), Metra 70-1727 Wire Harness Adapter is the standard harness adapter. Navigation-equipped RTL and RTX trims require a dedicated navigation bypass harness in addition to the standard radio harness. The Ridgeline shares its platform with the Pilot and Odyssey of the same era, and in many cases the same harness adapter part numbers apply across all three vehicles. Always confirm your trim’s navigation status before purchasing harness components.
Does the 2006–2014 Honda Ridgeline have a factory amplifier?
RTL and RTX trims of the 1st generation Ridgeline include a factory-amplified audio system. The Amplifier is typically located under the driver’s seat. RT and RTS trims use a passive, non-amplified speaker configuration driven directly from the head unit. Replacing the head unit in an amplified Ridgeline requires either a bypass harness that routes the new head unit’s signal around the factory Amplifier or an integration adapter that preserves the factory amplifier in the signal chain.
What is unique about installing audio equipment in a 2006–2014 Honda Ridgeline?
The 1st generation Ridgeline’s most distinctive installation consideration is its in-bed trunk. This lockable, weatherproof storage compartment under the truck bed floor is an ideal location for mounting an aftermarket Amplifier or subwoofer enclosure — it keeps audio equipment out of the cab, protects it from the elements, and frees up cab space. Wiring from the cabin to the in-bed trunk should be routed through the existing body grommets along the passenger side of the bed wall to maintain weatherproofing.
What size are the front door speakers in a 2006–2014 Honda Ridgeline?
The 1st generation Ridgeline uses 6 1/2″ Speakers in the front door panels across all trims. RTL and RTX trims with the premium audio system include A-pillar tweeters in addition to the front door speakers. Rear cab speakers are located in the rear seat area door panels on crew cab configurations. Standard 6 1/2″ Aftermarket Speakers fit the front door locations without modification on all trim levels.
How do I retain steering wheel audio controls when replacing the radio in a 2006–2014 Honda Ridgeline?
The 1st generation Ridgeline uses Honda’s resistive steering wheel control system on RTL and RTX trims. A resistive SWC retention interface such as the PAC SWI-RC is compatible with this generation’s SWC system. The 1st gen Ridgeline was produced before Honda transitioned to CAN-bus SWC, so a standard resistive interface is all that is needed. RT and RTS trims do not include steering wheel audio controls and require no SWC interface during a Head Unit swap.
