Construction & Design:
The Holley EFI Drive-By-Wire Harness is built with durability and precision in mind. Utilizing TXL grade copper wiring, it offers excellent conductivity while minimizing weight and bulk. The wiring is protected by a high-temperature sleeve and routed through a split-loom braid, providing resistance against heat, abrasion, and environmental factors. Every connector and termination is designed to meet or exceed OEM standards, ensuring a secure, reliable connection that fits perfectly with the Gen III HEMI’s early pedal type throttle system.
This attention to detail in materials and engineering guarantees long-lasting performance even in demanding engine bay conditions.
Installation & Fitment:
Installation is straightforward for vehicles equipped with the early pedal type drive-by-wire throttle system on Gen III HEMI engines from 2005 through 2007. The harness plugs directly into the factory throttle pedal connector, which features a larger connector design unique to early models. No modifications are required to the throttle body connector, as it remains consistent across all Gen III HEMI engines. This plug-and-play design simplifies integration with Holley EFI systems, making it an ideal choice for engine swaps and performance upgrades.
What's Included:
Ideal For:
This harness is perfect for automotive enthusiasts, professional tuners, and engine builders working with early Gen III HEMI engines who want to leverage Holley EFI’s advanced fuel and spark control. It is especially suited for those performing power upgrades, engine swaps, or integrating forced induction and other power adders requiring precise electronic throttle control.
Holley EFI delivers standalone engine management and EFI systems built for everything from engine swaps to serious horsepower builds.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
