Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 73 wires · 10 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 | M170-A-23 | M170-A-11 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | M170-A-54 | M170-A-11 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | M170-A-11 | M170-A-16 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 4 | M170-A-14 | M170-A-16 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | M170-A-14 | M170-A-23 | open (OL) | power ground must not touch +12 V supply | |
| 6 | M170-A-14 | M170-A-54 | open (OL) | power ground must not touch +12 V supply | |
| 7 | M170-A-23 | M170-A-16 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 8 | M170-A-54 | M170-A-16 | open (OL) | +12 V supply must not touch 5 V sensor reference |

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-X60003 31: Knock sensor, cylinders 4-6 (A): no free knock input on MoTeC M170 - OEM-X60003 32: Knock sensor, cylinders 4-6 (B): no free knock input on MoTeC M170 - OEM-X60003 48: Knock sensor shield: no shield pin on MoTeC M170 - OEM-X60002 19: O2 sensor heater, bank 2 post-cat: no free heater_low_side/low_side/ls_hs/hbridge on MoTeC M170 - OEM-X60002 7: O2 sensor heater, bank 1 post-cat: no free heater_low_side/low_side/ls_hs/hbridge on MoTeC M170 - OEM-X60003 41: VANOS exhaust solenoid: no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-X60003 42: Evap purge valve: no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-X60003 45: Map-controlled thermostat: no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-X60003 49: DISA intake flap: no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-X60002 18: O2 sensor signal, bank 2 post-cat: no free o2_narrowband/analog_0_5 on MoTeC M170
