Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 86 wires · 13 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-13 | MS3PROEVOHC-A-8 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 3 | MS3PROEVOHC-A-35 | MS3PROEVOHC-A-8 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 4 | MS3PROEVOHC-B-3 | MS3PROEVOHC-A-35 | open (OL) | power ground must not touch +12 V supply | |
| 5 | MS3PROEVOHC-B-3 | MS3PROEVOHC-A-8 | open (OL) | power ground must not touch 5 V sensor reference |

A digital input used as a ground/identification strap (e.g. AT/MT ID is grounded on manual cars) is compatible with a sensor ground. |
| info | NET_FAMILY | OEM-X60003-49 ↔ MS3PROEVOHC-B-2 | OEM-X60003-49 "DISA intake flap" [low_side_out] is wired to MS3PROEVOHC-B-2 "Injector out B" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | UNMAPPED | OEM | 2 optional OEM pins are not mapped: OEM-X60003-31 Knock sensor, cylinders 4-6 (A); OEM-X60003-32 Knock sensor, cylinders 4-6 (B) |

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (E46 K-bus/CAN); not documented for this ECU - This car has EWS 3.3 (rolling code) 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. Not wired: - OEM-X60001 7: Battery constant (terminal 30): AMP EFI MS3Pro EVO+ HC has no battery-constant input; not needed - OEM-X60003 31: Knock sensor, cylinders 4-6 (A): no free knock input on AMP EFI MS3Pro EVO+ HC - OEM-X60003 32: Knock sensor, cylinders 4-6 (B): no free knock input on AMP EFI MS3Pro EVO+ HC - MS3PROEVOHC-B 19: Digital switched 12V in: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
