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.
| Status | draft · not yet verified: nobody has reported building and running this harness |

| Open errors | 19: read the Findings page before cutting any wire |
| Size of the job | 51 wires · 7 connectors · 3 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |

| Order of work | 1. 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 A | Probe B | Expect | Why | Reading |
|---|---|---|---|---|---|
| 1 | T4-C1-31 | T4-C2-21 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | T4-C2-24 | T4-C2-21 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 3 | T4-C2-24 | T4-C1-31 | open (OL) | 5 V sensor reference must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

| warn | NO_FUEL_PUMP | fuel pump | This engine harness has no fuel-pump control path: no fuel-pump relay output is wired to the new ECU. If the stock car switches the pump outside the ECU (an airflow-meter contact or a separate module), the standalone must drive the pump relay itself — see the install notes for this car. |

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 4 ignition outputs for 8 cylinders: wasted spark (pair coils per firing order) - Only 4 injector outputs for 8 injectors: batch / semi-sequential injection - 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 41: Camshaft position bank 2 (CMP2): no free cam_vr/cam_hall/frequency_in input on DTAFast T4 - OEM-C175E 42: Camshaft position bank 2 exhaust (CMP2 EX): no free cam_vr/cam_hall/frequency_in input on DTAFast T4 - OEM-C175E 92: Ignition coil on plug D (COP-D): no free ignition output on DTAFast T4 - OEM-C175E 93: Ignition coil on plug A (COP-A): no free ignition output on DTAFast T4 - OEM-C175E 94: Ignition coil on plug C (COP-C): no free ignition output on DTAFast T4 - OEM-C175E 95: Ignition coil on plug B (COP-B): no free ignition output on DTAFast T4 - OEM-C175E 81: Throttle actuator control motor − (TACM−): needs a paired H-bridge on DTAFast T4 (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 DTAFast T4 (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - T4-C1 13: Power Ground 1: required by DTAFast T4 but no stock pin feeds it; wire by hand - T4-C1 14: Power Ground 2: required by DTAFast T4 but no stock pin feeds it; wire by hand - T4-C3 26: Permanent 12v: required by DTAFast T4 but no stock pin feeds it; wire by hand - T4-C3 27: Permanent 12v: required by DTAFast T4 but no stock pin feeds it; wire by hand - Fuel-pump control: DTAFast T4 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. Not wired: - OEM-C175E 53: Knock sensor 1 bank 1 signal (KS1+): no free knock input on DTAFast T4 - OEM-C175E 68: Knock sensor 2 bank 1 signal (KS2+): no free knock input on DTAFast T4 - OEM-C175E 39: Crankshaft sensor shield/drain: no shield pin on DTAFast T4 - OEM-C175E 36: Universal HEGO 2nd pump current (UO2SIP-21): no free wb_ip on DTAFast T4 - OEM-C175E 51: Universal HEGO 2nd sense (UO2SN-21): no free wb_vs on DTAFast T4 - OEM-C175E 21: Universal HEGO 2nd reference (UREF-21): no free wb_vgnd on DTAFast T4 - OEM-C175E 59: Manifold heater (CE511) or IMRC charge-motion valve (CE315, 5.0L RHD): not classified in the library; wire by hand - OEM-C175E 60: IMTV monitor (CE923) or intake manifold tuning valve (CE316, 5.0L RHD): not classified in the library; wire by hand
