PAC Radio Replacement Interface for Chrysler Dodge Jeep RAM (2004-2017) — retains chimes & steering wheel controls

PAC's Radio Replacement Interface for Chrysler, Dodge, Jeep and RAM (2004–2017) is a plug-and-play harness that lets you swap aftermarket radios while preserving vehicle chimes, steering wheel controls and critical data signals.

Swapping a factory head unit in many Chrysler-era cars and trucks can disable chimes, steering-wheel buttons, or safety triggers unless you install an intelligent interface. This PAC module connects to CAN Bus systems, supplies accessory power, and keeps vehicle data and warning tones intact so the car functions as expected after installation. It supports both amplified and non-amplified factory audio systems and includes the necessary SWI-CAN modules for model years covered.

How does this interface keep the car's warning chimes and features working?

The PAC interface monitors and translates CAN Bus messages so factory warning tones (backup chime, low fuel, door/hatch ajar, memory seat alerts) continue to play through an aftermarket radio. It maintains the vehicle's data paths and supplies specific trigger outputs to preserve functions tied to the original radio.

• Retains backup chimes and other factory warning tones
• Preserves memory seat alerts and low-fuel notifications
• Maintains vehicle data on the CAN Bus so other modules remain functional

Will my steering wheel audio controls keep working with an aftermarket head unit?

Yes — the interface provides a single-wire output designed to connect to a steering wheel control (SWC) module, enabling basic button integration with most aftermarket radios. PAC includes SWI-CAN/SWI-CAN2 compatibility to bridge Chrysler CAN systems to aftermarket control interfaces.

• Single-wire steering wheel control output for popular SWC modules
• Compatible with SWI-CAN and SWI-CAN2 modules for 2005–2011 models
• Works with both amplified and non-amplified factory audio systems

What vehicle signals and power outputs does the module provide?

The harness generates a 12V accessory (RAP) output and supplies vehicle speed (VSS), illumination, parking brake, and reverse trigger outputs so aftermarket radios can use OEM inputs. It also includes a break wire where required, and a built-in buzzer to manage chime functions if the replacement radio doesn't supply them.

• 12V accessory (RAP) output to power the new head unit
• VSS, illumination, parking brake, and reverse trigger outputs included
• Built-in buzzer and break wire supplied for chime and safety signals

Which models and years are supported, and are there any limitations?

The interface is tailored for select Chrysler, Dodge, Jeep and RAM vehicles from roughly 2004 through 2017 that use CAN Bus communications. It retains most factory features but does not preserve blind spot detection systems; verify compatibility with your exact model and year before purchase.

• Designed for select 2004–2017 Chrysler, Dodge, Jeep and RAM vehicles
• Includes SWI-CAN and SWI-CAN2 support for 2005–2011 installations
• Does not retain blind spot detection systems — confirm vehicle feature set

Who is this for: This PAC radio replacement interface is for DIY installers, professional car audio technicians, and owners replacing factory radios in supported Chrysler-era vehicles who want to keep OEM chimes, steering-wheel control functionality and critical vehicle triggers working with an aftermarket head unit. If you need to preserve vehicle data paths, generate accessory power, and maintain safety or convenience chimes while upgrading audio, this harness provides the necessary CAN Bus translation and outputs. Always check your vehicle's year and equipment list before ordering to ensure full compatibility.
