Installation and ordering

Confirm connector type, wiring, supply voltage and compatibility with the ECU or connected device before purchase. Follow the relevant Link wiring diagram, calibration and mounting instructions. CAN devices require a compatible CAN configuration and correct bus termination. Accessories are included only where they are explicitly listed below.

Installation and Compatibility Checks

Check the engine generation, throttle arrangement and connector compatibility. Install with appropriate power protection, grounds and ECU calibration; a wiring harness does not replace a tuned calibration.
