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

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).

warnDATASET_GAPMustang GT PCM C175E22 of 70 cavities on Mustang GT PCM C175E have no pin data (11,12,13,14,15,19,22,24,25,26,28,29,32,33,37,38,43,58,63,64,65,66). Anything there is invisible to these checks.
warnDBW_MOTOR_CURRENTT12-C1-6Cannot confirm T12 can drive the throttle motor: neither the motor stall current (TB-J-M+) nor the peak rating of T12-C1-6 "Motor 1 +" is known.
warnDBW_MOTOR_CURRENTT12-C1-7Cannot confirm T12 can drive the throttle motor: neither the motor stall current (TB-J-M-) nor the peak rating of T12-C1-7 "Motor 1 -" is known.
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.
infoUNMAPPEDOEM3 optional OEM pins are not mapped: OEM-C175E-39 Crankshaft sensor shield/drain; OEM-C175E-59 Manifold heater (CE511) or IMRC charge-motion valve (CE315, 5.0L RHD); OEM-C175E-60 IMTV monitor (CE923) or intake manifold tuning valve (CE316, 5.0L RHD)

Notes

Fit check: unconfirmed. Confirm these before building: - Needs CAN (ford_mustang_2011_14); not documented for this ECU - 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: - Fuel-pump control: DTAFast T12 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 39: Crankshaft sensor shield/drain: no shield pin on DTAFast T12 - 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
