Holley always comes out to win. With their new EFI plug and play harnesses, your Ford EFI build is going to turn heads. It uses all the factory connectors, so there are no wires that you’re going to cut or put in the wrong location. Details below.

Official Release:

Holley is proud to announce the release of plug and play EFI harnesses to use Holley EFI on Ford Coyote and Mod Motor platforms.

Holley’s plug and play harnesses plug right into your factory sensors, including crank, cam, TPS, coolant, and much more. This also includes your factory actuators; ignition coils, fuel injectors, and idle air control. There are also connectors for Holley fuel and oil pressure sensors and expanded inputs and outputs. 4R70W transmission control will also be available soon when using the Dominator ECU, which also allows for plug and play drive-by-wire control as well.

With Holley EFI, Coyote and Mod Motor owners can take full control of their fuel and spark, as well as power adders such as superchargers, turbos, nitrous, and water/meth injection. The self-tuning fuel strategies and intuitive software make maximizing the performance from your Coyote or Mod Motor-powered vehicle easier than ever.

Features:

• Plug and play harnesses use factory connectors
• With Holley EFI owners can take full control of their fuel and spark
• Control your transmission and drive-by-wire throttle
