Aerpro SWTO2C Steering Wheel Control Interface Toyota Various Models
An analogue steering wheel control interface engineered for various Toyota vehicles with Fujitsu Ten or Matsushita original head units and a 20-pin connector, the SWTO2C retains factory steering wheel controls with a vehicle-specific plug connection that requires no cutting of the factory wiring harness.
Product Overview
The Aerpro SWTO2C is an analogue steering wheel control interface designed for various Toyota vehicles fitted with Fujitsu Ten or Matsushita original head units and a 20-pin connector. It includes a harness fitted with a vehicle-specific plug that connects directly into the existing factory wiring in the vehicle without cutting or modifying the factory harness. The SWTO2C is compatible with SW-type patch leads (sold separately). Custom button remapping is available and requires a USB-C cable (sold separately).
Installation is simplified when the SWTO2C is paired with the optional Aerpro APP8 Headunit Secondary ISO Harness (sold separately), which connects between the aftermarket head unit and the SWTO2C interface. The aftermarket head unit must be SWC compatible and steering wheel control functions may vary from OEM functions. The SWTO2C is not compatible with factory OEM amplified or factory upgraded systems. Use the Aerpro Vehicle Selector to confirm the correct part for your specific vehicle before purchase.
