Auxiliary Connector Wiring Diagram

The Elite Pro Plug-in for the Ford Falcon Barra runs the engine on the factory harness, and its auxiliary connector is where your extra sensors and outputs go. This diagram shows what lives on that plug.

The Elite Pro Plug-in ECU for the Ford Falcon I6 Barra connects straight to the factory wiring. Anything the factory loom doesn't cover, such as extra sensors, outputs or switches for added features, connects through the auxiliary connector instead. The wiring diagram shows which pin on that connector carries which input or output.

When you'll need it

  • Adding sensors or controls the factory Falcon never had.
  • Building or checking an auxiliary sub-harness.
  • Matching a function in ESP to the physical pin you've wired.

What to check

  • Confirm every pin number against the diagram before crimping, and look at the connector from the side the diagram is drawn from.
  • Make sure each wire goes to an input or output type that suits the device, and assign it to the same function in ESP.
  • Ground sensors to an ECU signal ground, not to a chassis bolt.
