Before you start
| Status | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 62 wires · 8 connectors · 4 part lines |
| Tools | 715131-1 · wire strippers · multimeter · heat gun + heat-shrink |
| Terminals | 316836-1 |
| 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-23 | M170-A-14 | open (OL) | +12 V supply must not touch power ground | |
| 3 | M170-A-11 | M170-A-16 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 4 | M170-A-11 | M170-A-34 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 5 | M170-A-14 | M170-A-16 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | M170-A-14 | M170-A-34 | open (OL) | power ground must not touch 5 V sensor reference | |
| 7 | M170-A-23 | M170-A-16 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 8 | M170-A-23 | M170-A-34 | open (OL) | +12 V supply must not touch 5 V sensor reference |

| warn | DATASET_GAP | RSX ECU A | 5 of 31 cavities on RSX ECU A have no pin data (8,13,14,17,31). Anything there is invisible to these checks. |
| warn | DATASET_GAP | RSX ECU B | 8 of 24 cavities on RSX ECU B have no pin data (11,12,14,16,19,20,22,24). Anything there is invisible to these checks. |

A switch on an analog input works with a pull-up and a threshold; an analog sensor on a digital input loses its value. |

Notes
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-E 9: Ignition switch signal (IG1): key-on 12 V sense — optional in a swap (the main relay is energized from keyed 12 V, not from this pin); MoTeC M170 has no dedicated key-on input - OEM-B 23: VTC oil control solenoid (-): no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-B 7: Reverse lockout solenoid (RVS, Type-S): no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-E 21: Evap vent shut valve (VSV): no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-E 31: Malfunction indicator lamp (MIL): no free low_side/ls_hs/injector/hbridge on MoTeC M170 - OEM-E 26: Engine speed pulse / tacho (NEP): no free tacho/frequency_out/low_side/ls_hs on MoTeC M170 - OEM-A 6: A/F sensor + (AFS+, wideband Ip): no free wb_ip on MoTeC M170 - OEM-A 16: A/F sensor - (AFS-, wideband Vs): no free wb_vs on MoTeC M170 - OEM-A 22: A/F sensor heater supply (AFSHTC+): no free heater_feed on MoTeC M170 - OEM-E 23: K-line (diagnostic): no free k_line on MoTeC M170 - OEM-E 24: Multiplex communication (SEFMJ): no free k_line on MoTeC M170 - OEM-E 27: Immobilizer code (IMOCD): not classified in the library; wire by hand - OEM-E 29: Service check signal (SCS): not classified in the library; wire by hand - OEM-E 30: Write enable signal (WEN): not classified in the library; wire by hand
