PAC Steering Wheel Control Interface SWI-RC-1 — Universal 3.5mm/Two-Wire, DIP-Switch & Web Setup

Replacing a factory radio doesn’t have to mean losing steering wheel control convenience. The PAC SWI-RC-1 combines DIP-switch pre-programming with on-the-fly button mapping through a web-based setup, allowing fast, reliable integration with CAN-Bus, Class II, GMLAN and many resistive analog steering wheel control systems. Its plug-and-play wiring and a 2-amp 12V accessory output simplify installations and reduce guesswork for both DIYers and professional installers.

How does the SWI-RC-1 keep my steering wheel controls working after a radio swap?

The SWI-RC-1 translates vehicle steering wheel commands into the wired remote or two-wire signals that most aftermarket radios expect. It supports both digital bus systems and resistive analog inputs, so it bridges the communication gap between your vehicle’s control module and new head unit.

• Supports CAN-Bus, GMLAN, Class II, LIN-Bus, IBUS, ACP, PCI and resistive SWC systems.
• Outputs to radios via 3.5mm wired remote jack or two-wire remote connections.
• Retains short-press/long-press and button reassignment where supported.

What setup options are available and how easy is installation?

Setup is flexible: use the DIP switches to select pre-programmed button maps or use the web-based SWI-RC-1 guide for model-specific instructions and on-the-fly programming. The guided web app ensures you have the latest firmware and the correct wiring diagram for your vehicle and radio brand.

• Pre-programmed configurations via DIP switch selection for quick installs.
• Web app-based, model-specific installation guidance with firmware updates.
• Classic SWI-RC-style manual programming for custom button assignments.

Which radios and vehicles are compatible with the SWI-RC-1?

The interface works with more than 3000 vehicles that have factory steering wheel controls and with most aftermarket radios that include a wired remote input (3.5mm jack or a labeled remote wire). Some specific radio models and rare vehicle control protocols are excluded; always verify compatibility via the PAC web guide before purchase.

• Vehicle compatibility: over 3000 late-model cars and trucks with factory SWC.
• Radio compatibility: requires a wired remote input labeled REM, W/R, Rem Cont, etc.
• Notable exceptions and radio limitations are detailed in PAC compatibility notes.

What additional features should I know about?

Beyond SWC translation, the SWI-RC-1 provides a 2-amp accessory 12V output for radios in CAN-Bus, LAN and Class II vehicles, removing the need to search for switched power sources. It also supports adaptive button behavior so common functions like source, volume, and presets remain accessible after the swap.

• 2-amp 12V accessory output for radio power/switching needs.
• Button function flexibility: short press, long press, and reassignment supported.
• Firmware-updatable via PAC web app to maintain current support.

Who is this for? Installers and vehicle owners replacing a factory radio who want to keep original steering wheel convenience will benefit most. The SWI-RC-1 fits technicians needing a quick, reliable retention solution as well as savvy DIYers comfortable following web-guided wiring diagrams. If your aftermarket radio has a wired remote input and your vehicle has factory steering wheel controls, this module streamlines integration and preserves commonly used steering wheel functions without complex programming.
