Before you start
| Status | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 76 wires · 10 connectors · 4 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 | PROTEUS-Black23-23 | PROTEUS-Black23-14 | open (OL) | +12 V supply must not touch power ground | |
| 2 | PROTEUS-Black23-23 | PROTEUS-White35-1 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | PROTEUS-Black23-14 | PROTEUS-White35-10 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | PROTEUS-Black23-14 | PROTEUS-White35-21 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | PROTEUS-Black23-23 | PROTEUS-White35-10 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 6 | PROTEUS-Black23-23 | PROTEUS-White35-21 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 7 | PROTEUS-White35-1 | PROTEUS-White35-10 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 8 | PROTEUS-White35-1 | PROTEUS-White35-21 | open (OL) | sensor ground must not touch 5 V sensor reference |

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-B 21: Backup power (battery constant): rusEFI Proteus has no battery-constant input; not needed - OEM-C 22: Knock sensor: 2 stock pins named "Knock sensor" without a documented polarity / pairing; wire by hand - OEM-C 3: Knock sensor: 2 stock pins named "Knock sensor" without a documented polarity / pairing; wire by hand - OEM-A 19: Tacho output: no free tacho/frequency_out/low_side/ls_hs on rusEFI Proteus - OEM-A 21: K-Line: no free k_line on rusEFI Proteus - OEM-A 10: Service check signal: not classified in the library; wire by hand - OEM-A 13: Immobilizer enable signal: not classified in the library; wire by hand - OEM-A 25: Immobilizer code: not classified in the library; wire by hand - PROTEUS-Black23 18: Ignition switch in: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
