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 errors10: 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
1MS3PROMINI-A-1MS3PROMINI-A-21open (OL)+12 V supply must not touch sensor ground
2MS3PROMINI-A-2MS3PROMINI-A-21open (OL)5 V sensor reference must not touch sensor ground
3MS3PROMINI-A-2MS3PROMINI-A-1open (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: - Drive-by-wire only with an add-on: AMP Drive-By-Wire 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) - This car has PATS immobilizer; needs a delete/bypass - Trigger pattern for Ford Coyote not checked yet 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 92: Ignition coil on plug D (COP-D): no free ignition output on AMP EFI MS3Pro Mini - OEM-C175E 93: Ignition coil on plug A (COP-A): no free ignition output on AMP EFI MS3Pro Mini - OEM-C175E 94: Ignition coil on plug C (COP-C): no free ignition output on AMP EFI MS3Pro Mini - OEM-C175E 95: Ignition coil on plug B (COP-B): no free ignition output on AMP EFI MS3Pro Mini - OEM-C175E 81: Throttle actuator control motor − (TACM−): needs a paired H-bridge on AMP EFI MS3Pro Mini (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 AMP EFI MS3Pro Mini (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - MS3PROMINI-A 22: Power ground: required by AMP EFI MS3Pro Mini but no stock pin feeds it; wire by hand - MS3PROMINI-A 23: Power ground: required by AMP EFI MS3Pro Mini but no stock pin feeds it; wire by hand - Fuel-pump control: AMP EFI MS3Pro Mini 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 AMP EFI MS3Pro Mini - OEM-C175E 68: Knock sensor 2 bank 1 signal (KS2+): no free knock input on AMP EFI MS3Pro Mini - OEM-C175E 39: Crankshaft sensor shield/drain: no shield pin on AMP EFI MS3Pro Mini - OEM-C175E 79: Heater O2 pre-cat 1st (HTR11): no free heater_low_side/low_side/ls_hs/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 83: Heater O2 post-cat 2nd (HTR22): no free heater_low_side/low_side/ls_hs/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 84: Heater O2 pre-cat 2nd (HTR21): no free heater_low_side/low_side/ls_hs/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 5: Variable camshaft timing valve 1 (VCT1): no free low_side/ls_hs/injector/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 4: Variable camshaft timing valve 2 (VCT2): no free low_side/ls_hs/injector/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 7: Variable camshaft timing valve 3 (VCT3): no free low_side/ls_hs/injector/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 6: Variable camshaft timing valve 4 (VCT4): no free low_side/ls_hs/injector/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 71: Canister purge valve (CANP): no free low_side/ls_hs/injector/hbridge on AMP EFI MS3Pro Mini - OEM-C175E 35: Universal HEGO 1st pump current (UO2SIP-11): no free wb_ip on AMP EFI MS3Pro Mini - OEM-C175E 36: Universal HEGO 2nd pump current (UO2SIP-21): no free wb_ip on AMP EFI MS3Pro Mini - OEM-C175E 50: Universal HEGO 1st sense (UO2SN-11): no free wb_vs on AMP EFI MS3Pro Mini - OEM-C175E 51: Universal HEGO 2nd sense (UO2SN-21): no free wb_vs on AMP EFI MS3Pro Mini - OEM-C175E 20: Universal HEGO 1st reference (UREF-11): no free wb_vgnd on AMP EFI MS3Pro Mini - OEM-C175E 21: Universal HEGO 2nd reference (UREF-21): no free wb_vgnd on AMP EFI MS3Pro Mini - OEM-C175E 57: Oil pressure switch (MTX): no free switch_in/frequency_in/analog_0_5 on AMP EFI MS3Pro Mini - 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
