Before you start

Not confident with automotive wiring? Have a professional harness builder or tuner do it, or check your work before first power-up. A wiring mistake can damage the ECU, the engine or the car, or start a fire.

Statusdraft · not yet verified: nobody has reported building and running this harness
Open errors15: read the Findings page before cutting any wire
Size of the job40 wires · 5 connectors · 1 part lines
ToolsCrimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink
Order of work1. Check every part against the parts list. 2. Cut and label every wire (labels: Export → Wire labels). 3. Crimp and pin connector by connector, ticking the build checklist. 4. Run the bench test with nothing plugged in and the battery disconnected. 5. Only then connect the ECU and power up.

Build checklist

Tick each box as you go. Continuity: meter from end to end, expect under 1 Ω.

Bench test (before first power-up)

Battery disconnected, ECU and every sensor unplugged. Meter on resistance. Each pair below must read open (OL): a reading means a pinched wire, a stray strand or a mis-pinned cavity. Then check continuity of every wire (last column of the build checklist).

#Probe AProbe BExpectWhyReading
1FT450-A-A13FT450-A-A12open (OL)+12 V supply must not touch sensor ground
2FT450-A-A14FT450-A-A12open (OL)5 V sensor reference must not touch sensor ground
3FT450-A-A14FT450-A-A13open (OL)5 V sensor reference must not touch +12 V supply

If any reading doesn't match, stop and get help before powering up.

Notes

Fit check: needs add-on. Resolve these before building: - No drive-by-wire; needs a cable-throttle conversion or an external DBW controller - Needs CAN (ford_mustang_2011_14); not documented for this ECU - No knock input; the stock knock sensor would be unused - Only 2 injector outputs for 8 injectors: batch / semi-sequential injection - Only 4 ignition outputs for 8 cylinders: wasted spark (pair coils per firing order) - This car has PATS immobilizer; needs a delete/bypass Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Open items: - OEM-C175E 56: Camshaft position bank 1 exhaust (CMP1 EX): no free cam_vr/cam_hall/frequency_in input on FuelTech FT450 - OEM-C175E 41: Camshaft position bank 2 (CMP2): no free cam_vr/cam_hall/frequency_in input on FuelTech FT450 - OEM-C175E 42: Camshaft position bank 2 exhaust (CMP2 EX): no free cam_vr/cam_hall/frequency_in input on FuelTech FT450 - OEM-C175E 92: Ignition coil on plug D (COP-D): no free ignition output on FuelTech FT450 - OEM-C175E 93: Ignition coil on plug A (COP-A): no free ignition output on FuelTech FT450 - OEM-C175E 94: Ignition coil on plug C (COP-C): no free ignition output on FuelTech FT450 - OEM-C175E 95: Ignition coil on plug B (COP-B): no free ignition output on FuelTech FT450 - OEM-C175E 81: Throttle actuator control motor − (TACM−): needs a paired H-bridge on FuelTech FT450 (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - OEM-C175E 82: Throttle actuator control motor + (TACM+): needs a paired H-bridge on FuelTech FT450 (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - FT450-A A7: Power ground: required by FuelTech FT450 but no stock pin feeds it; wire by hand - Fuel-pump control: FuelTech FT450 needs to drive the fuel pump, but the stock ECU has no fuel-pump output (an airflow-meter contact or a separate module runs it). Add a fuel-pump relay on a spare low-side output — see the install notes for this car.
