This is the factory BF Falcon ECU pinout as used by the Haltech Elite Pro Plug-in ECU for the Ford Falcon I6 Barra. The ECU has three connectors, A, B and C. Pin numbers below follow Haltech's A, B and C connector numbering. Use it when you're probing with a multimeter, adding a sensor, or chasing a fault. BA and FG cars have their own pinout pages, so use the BA pinout or FG pinout for those.
Fuel and ignition
| Cylinder | Injector pin | Ignition pin |
|---|---|---|
| 1 | A14 | A35 |
| 2 | A07 | A46 |
| 3 | A15 | A12 |
| 4 | A04 | A34 |
| 5 | A08 | A24 |
| 6 | A03 | A23 |
If you're upgrading the coils, the BA/BF Barra ignition harness is the neat way to do it.
Crank, cams and cam control
- A30 / A41: crank position sensor, positive and negative
- A31: intake cam position (home)
- A33: exhaust cam position
- A05: intake cam control solenoid
- A06: exhaust cam control solenoid
Drive by wire
- A27 / A28: throttle motor, positive and negative
- A44 / A16: throttle position sensors 1 and 2
- B17 / B18: accelerator pedal sensors 1 and 2
- B19: pedal sensor 3, not used
Engine sensors
| Sensor | Pin |
|---|---|
| Manifold pressure | A38 |
| Boost pressure (turbo cars only) | C02 |
| Intake air temperature | A25 |
| Coolant temperature | A45 |
| Oil temperature | A13 |
| Oil pressure switch | A26 |
| Knock sensor 1 | A29 |
| Pre-cat narrowband O2 signal / heater | B08 / A09 |
| Post-cat O2 signal / heater (not used) | C18 / C19 |
| A/C pressure | B15 |
Sensor supplies and grounds are shared across the plugs. The 5V sensor supply appears on A21, A36, B20, B28, B45 and C30. Sensor signal ground appears on A22, A32, A40, B21, B29 and B33.
Switch and speed inputs

- B25 / B32: brake pedal switches 1 and 2
- B16: cruise control
- B30: reverse switch
- B31: power steering switch
- B06: collision detection
- B07: driveshaft vehicle speed (cars without ABS)
- B38: start signal from the ignition switch
Outputs
- B27: fuel pump
- B24 / B35: thermo fans 1 and 2
- B02: A/C control
- B04: starter motor relay
- B37: engine control relay
- B22: evaporative emissions control
- B03: dual intake runner (non-turbo engines only)
- C21: boost control (turbo engines only)
- B36: vehicle speed output
- B42: reverse lockout
Power, grounds and CAN
| Circuit | Pins |
|---|---|
| ECU power (+13.8V) | B34, B46, C23 |
| Permanent battery (+12V) | B40 |
| Ignition switch (+12V) | B09 |
| Battery negative | B01, B10, B11, B12, B23, C01 |
| CAN high / low | B13 / B14, and C03 / C04 |
Automatic transmission pins
The BF's 4-speed automatic control pins are listed for completeness, but Haltech doesn't currently support the 4-speed on this ECU. They are A02 (power control solenoid), A17 and A18 (MCS 1 and 2), A19 and A20 (shift solenoids 1 and 2), A37 (transmission fluid temperature), A39 (variable pressure solenoid), A43 (lock-up solenoid), and B41 and B43 (range switch inputs 1 and 2). If you're swapping transmissions, read ABS module status for transmission swaps first.
Unused pins
Nothing is assigned to A01, A10, A11, A42, B26, B39, B44, C05 through C17, C20, C22, or C24 through C29.
Back-probe with the plugs connected where you can, and never force a meter lead into a terminal. A spread terminal causes the kind of intermittent fault that eats a whole weekend. Want the connector face diagram? Ask us and we'll send it over with advice for your build.
