Overview

The Holley 558-219 Injector Driver Harness is compatible with HP or Dominator EFI systems. It offers Ti-VCT Cam control down to 400 RPM and ensures commanded timing is matched within 1 degree. The harness includes 4 built-in diagnostic LEDs for easy troubleshooting of cam or crank sensor failures, and integrated stock cam position tables to eliminate tuning guesswork. It enables CANBus communication between the Coyote Ti-VCT and Holley EFI ECU for high-speed data transfer and diagnostics. Installation requires an external MAP sensor, with part number 538-24 recommended for N/A applications. Pre-calibrated Ford sensor drop-downs are available in the Holley EFI Software, and the plug-and-play Ti-VCT Sub Harness is designed specifically for 2013-2017 Coyote Engines, with labeled connectors for easy identification.
