Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | 7: read the Findings page before cutting any wire |
| Size of the job | 68 wires · 8 connectors · 1 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 | MS3PROEVOHC-A-35 | MS3PROEVOHC-A-13 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | MS3PROEVOHC-A-8 | MS3PROEVOHC-A-13 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 3 | MS3PROEVOHC-A-8 | MS3PROEVOHC-A-35 | open (OL) | 5 V sensor reference must not touch +12 V supply |

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 2026-10-06. Review every wire against both manuals before building. Open items: - MS3PROEVOHC-B 3: Ground: required by AMP EFI MS3Pro EVO+ HC but no stock pin feeds it; wire by hand - MS3PROEVOHC-B 5: Ground: required by AMP EFI MS3Pro EVO+ HC but no stock pin feeds it; wire by hand - MS3PROEVOHC-B 7: Ground: required by AMP EFI MS3Pro EVO+ HC but no stock pin feeds it; wire by hand - MS3PROEVOHC-B 9: Ground: required by AMP EFI MS3Pro EVO+ HC but no stock pin feeds it; wire by hand Not wired: - OEM-C175E 35: Universal HEGO 1st pump current (UO2SIP-11): no free wb_ip on AMP EFI MS3Pro EVO+ HC - OEM-C175E 36: Universal HEGO 2nd pump current (UO2SIP-21): no free wb_ip on AMP EFI MS3Pro EVO+ HC - OEM-C175E 50: Universal HEGO 1st sense (UO2SN-11): no free wb_vs on AMP EFI MS3Pro EVO+ HC - OEM-C175E 51: Universal HEGO 2nd sense (UO2SN-21): no free wb_vs on AMP EFI MS3Pro EVO+ HC - OEM-C175E 20: Universal HEGO 1st reference (UREF-11): no free wb_vgnd on AMP EFI MS3Pro EVO+ HC - OEM-C175E 21: Universal HEGO 2nd reference (UREF-21): no free wb_vgnd on AMP EFI MS3Pro EVO+ HC - 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 - MS3PROEVOHC-B 19: Digital switched 12V in: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
