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 errors4: read the Findings page before cutting any wire
Size of the job51 wires · 12 connectors · 3 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).

warnNO_FUEL_PUMPfuel pumpThis 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: - Drive-by-wire only with an add-on: Link RET 115-1000 - Needs CAN (ford_mustang_2011_14); not documented for this ECU - Trigger pattern for Ford Coyote not found in the ECU's docs (No shipped Coyote trigger mode (only Ford Barra half-sync); staff confirm 36-1 Gen2 / 60-2 Gen3 but manual/custom only) - 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 2026-10-23. Review every wire against both manuals before building. Open items: - TB-J M+: Throttle motor +: needs a paired H-bridge on Link G4X MonsoonX (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - TB-J M-: Throttle motor −: needs a paired H-bridge on Link G4X MonsoonX (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - APP-J SIG2: Pedal position 2: no free analog_0_5 on Link G4X MonsoonX - TB-J TPS2: Throttle position 2: no free analog_0_5 on Link G4X MonsoonX - Fuel-pump control: Link G4X MonsoonX 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) and the ECU has no fuel-pump output pin to wire — add a fuel-pump relay on a spare low-side output, see the install notes for this car. Not wired: - OEM-C175E 68: Knock sensor 2 bank 1 signal (KS2+): no free knock input on Link G4X MonsoonX - OEM-C175E 35: Universal HEGO 1st pump current (UO2SIP-11): no free wb_ip on Link G4X MonsoonX - OEM-C175E 36: Universal HEGO 2nd pump current (UO2SIP-21): no free wb_ip on Link G4X MonsoonX - OEM-C175E 50: Universal HEGO 1st sense (UO2SN-11): no free wb_vs on Link G4X MonsoonX - OEM-C175E 51: Universal HEGO 2nd sense (UO2SN-21): no free wb_vs on Link G4X MonsoonX - OEM-C175E 20: Universal HEGO 1st reference (UREF-11): no free wb_vgnd on Link G4X MonsoonX - OEM-C175E 21: Universal HEGO 2nd reference (UREF-21): no free wb_vgnd on Link G4X MonsoonX - OEM-C175E 44: Intake manifold monitor (IMM): no free map/analog_0_5 on Link G4X MonsoonX - OEM-C175E 45: Intake port deactivation valve position: no free analog_0_5 on Link G4X MonsoonX - OEM-C175E 30: Engine oil level switch (EOL): no free switch_in/frequency_in/analog_0_5 on Link G4X MonsoonX - OEM-C175E 48: Oil pressure switch: no free switch_in/frequency_in/analog_0_5 on Link G4X MonsoonX - OEM-C175E 57: Oil pressure switch (MTX): no free switch_in/frequency_in/analog_0_5 on Link G4X MonsoonX - 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
