Before you start
Not confident with automotive wiring? Have a professional harness builder or tuner do it, or check your work before first power-up. A wiring mistake can damage the ECU, the engine or the car, or start a fire.
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 82 wires · 14 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 | OEM-X60001-8 | NEXUSS3-C-2 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | MAIN-R-COIL- | MAIN-R-COIL+ | open (OL) | power ground must not touch +12 V supply | |
| 3 | MAIN-R-COIL- | MAIN-R-OUT | open (OL) | power ground must not touch +12 V supply | |
| 4 | MAIN-R-COIL- | NEW-BATT-1 | open (OL) | power ground must not touch +12 V supply | |
| 5 | MAIN-R-COIL- | NEXUSS3-C-25 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | MAIN-R-COIL- | OEM-X60001-8 | open (OL) | power ground must not touch +12 V supply | |
| 7 | NEXUSS3-C-2 | MAIN-R-COIL+ | open (OL) | sensor ground must not touch +12 V supply | |
| 8 | NEXUSS3-C-2 | MAIN-R-OUT | open (OL) | sensor ground must not touch +12 V supply | |
| 9 | NEXUSS3-C-2 | NEW-BATT-1 | open (OL) | sensor ground must not touch +12 V supply | |
| 10 | NEXUSS3-C-2 | NEXUSS3-C-25 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 11 | NEXUSS3-C-25 | MAIN-R-COIL+ | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 12 | NEXUSS3-C-25 | MAIN-R-OUT | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 13 | NEXUSS3-C-25 | NEW-BATT-1 | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 14 | OEM-X60001-8 | NEXUSS3-C-25 | open (OL) | +12 V supply must not touch 5 V sensor reference |
If any reading doesn't match, stop and get help before powering up.

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (E46 K-bus/CAN); not documented for this ECU - Main power feed not sourced — Nexus S3's relay-fed power input is drawn through the main relay, but the feed's fuse rating is not in the library yet - This car has EWS 3.3 (rolling code) immobilizer; needs a delete/bypass Auto-mapped by auto_map() from the library pin data on 2026-10-23. Review every wire against both manuals before building. Not wired: - OEM-X60001 7: Battery constant (terminal 30): Haltech Nexus S3 has no battery-constant memory input; not needed - OEM-X60003 31: Knock sensor, cylinders 4-6 (A): no free knock input on Haltech Nexus S3 - OEM-X60003 32: Knock sensor, cylinders 4-6 (B): no free knock input on Haltech Nexus S3 - OEM-X60003 48: Knock sensor shield: no shield pin on Haltech Nexus S3 - OEM-X60003 40: VANOS intake solenoid: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60003 41: VANOS exhaust solenoid: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60003 42: Evap purge valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60003 45: Map-controlled thermostat: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60003 49: DISA intake flap: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60003 52: Secondary air pump valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60004 18: Exhaust flap valve control: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60004 20: Fuel tank leakage diagnostic pump: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60004 30: Fuel tank leakage diagnostic valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60004 4: Cooling fan control: no free low_side/relay_control/heater_low_side/ls_hs/injector on Haltech Nexus S3 - OEM-X60004 17: Engine speed (RPM) output: no free tacho/frequency_out/low_side/ls_hs on Haltech Nexus S3 - OEM-X60003 27: Engine oil temperature: no free thermistor/analog_0_5 on Haltech Nexus S3 - OEM-X60004 38: Coolant outlet temperature sensor: no free thermistor/analog_0_5 on Haltech Nexus S3 - OEM-X60004 32: Diagnostic TX (K-line): no free k_line on Haltech Nexus S3 - OEM-X60003 46: Idle speed control, close: no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-X60003 47: Idle speed control, open: no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-X60004 33: Drive-away protection (anti-theft): not classified in the library; wire by hand
