Specialized Barra 4.0L Wiring for FG Falcon
The Elite 2500 Terminated Harness for Ford Falcon FG allows for the seamless integration of a Haltech Elite 2500 ECU into the sophisticated CAN-bus environment of the FG-series Falcon. The Barra 4.0L Turbo is a powerhouse, but the factory PCM often limits tuning capabilities. This harness bridges the gap, allowing full standalone control of the engine while integrating with the vehicle’s chassis systems. Specifically terminated for Factory Bosch EV1 injector connectors, this kit is designed for vehicles retaining the OEM fuel rail/injector style or aftermarket upgrades that utilize the EV1 standard.
Engineering Deep-Dive: FG CAN Bus and VCT
The FG Falcon utilizes a complex CAN bus network for dashboard and chassis functions. This Haltech harness is engineered to work in parallel or replacement configurations (depending on the specific setup depth) to ensure critical vehicle functions remain operational. It provides full control over the Barra’s Variable Cam Timing (VCT) system, allowing for precise tuning of the intake and exhaust cams to maximize torque and spool-up. The harness includes a fuse block to supply clean power to the Haltech ECU and engine components, isolating the performance electronics from the rest of the car.
Operational Benefits: Plug-and-Play Tuning
This harness saves hours of wiring time. It connects directly to the cam sensors, crank sensor, VCT solenoids, MAP, air temp, and coolant temp sensors. By using the Elite 2500, tuners gain access to advanced features like knock control, boost control by gear, and flex-fuel capability (sensor added separately). The harness is built to withstand the heat of the turbo side of the engine, using high-quality loom and connectors.

Summary & Includes
The HT-141389 is the key to unlocking the FG Barra. It provides full standalone control with OEM-level integration.
Includes:
- 1 x Engine Harness & Fuse Block
- 1 x Connector Pack
- 1 x Quick Start Guide
Required Add-on: The Ignition Module is NOT included in this kit. If you are using the factory coils, you will likely need the Haltech Ignition Module (HT-020036) to drive them, as the Elite does not have built-in high-current coil drivers for “dumb” coils.
