Show original supplier description

The iWire iDCCD is a wiring harness system that unlocks the full potential of the Driver Controlled Center Differential (DCCD) for 2022+ WRX models equipped with an STI 6-speed transmission swap. While Subaru did not offer the VB STi from the factory, this iDCCD controller allows enthusiasts to implement this advanced feature. It leverages the vehicle's CAN bus network for a plug-and-play installation, incorporating vehicle-specific harness and bracketry. The system provides intelligent automatic control modes with user adjustability, and integrates with an OEM STi control panel. A smartphone app allows for configuration, customization, and display of system data. By monitoring real-time vehicle data, the iDCCD makes numerous adjustments to optimize center differential lock, improving grip, stability, and overall driving experience across various conditions. The design also includes seamless CAN bus integration and supports firmware updates for future enhancements. This harness is specifically engineered for the 2022+ WRX when fitted with a DCCD-equipped transmission. The iDCCD system is designed, developed, and built by iWire in the USA, offering precision without compromise.
