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 | 2: read the Findings page before cutting any wire |
| Size of the job | 80 wires · 13 connectors · 3 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |
| Terminals | 3-1447221-4 |
| 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 | T8-C1-31 | T8-C2-21 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | T8-C3-26 | T8-C2-21 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | T8-C1-13 | NEW-BATT-1 | open (OL) | power ground must not touch +12 V supply | |
| 4 | T8-C1-13 | T8-C1-31 | open (OL) | power ground must not touch +12 V supply | |
| 5 | T8-C1-13 | T8-C2-24 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | T8-C1-13 | T8-C3-26 | open (OL) | power ground must not touch +12 V supply | |
| 7 | T8-C1-31 | T8-C2-24 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 8 | T8-C2-21 | NEW-BATT-1 | open (OL) | sensor ground must not touch +12 V supply | |
| 9 | T8-C2-21 | T8-C2-24 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 10 | T8-C2-24 | NEW-BATT-1 | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 11 | T8-C3-26 | T8-C2-24 | 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: needs add-on. Resolve these before building: - No drive-by-wire; needs a cable-throttle conversion or an external DBW controller - Needs CAN (E46 K-bus/CAN); not documented for this ECU - No knock input; the stock knock sensor would be unused - 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. Open items: - OEM-X60003 43: Throttle motor − (M−): needs a paired H-bridge on DTAFast T8 (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - OEM-X60003 44: Throttle motor + (M+): needs a paired H-bridge on DTAFast T8 (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) Not wired: - OEM-X60003 29: Knock sensor, cylinders 1-3 (A): no free knock input on DTAFast T8 - OEM-X60003 30: Knock sensor, cylinders 1-3 (B): no free knock input on DTAFast T8 - OEM-X60003 31: Knock sensor, cylinders 4-6 (A): no free knock input on DTAFast T8 - OEM-X60003 32: Knock sensor, cylinders 4-6 (B): no free knock input on DTAFast T8 - OEM-X60003 48: Knock sensor shield: no shield pin on DTAFast T8 - OEM-X60004 26: Ignition switch (terminal 15): key-on 12 V sense — handled by the chassis (it energises the main relay); not needed on this harness - OEM-X60003 49: DISA intake flap: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T8 - OEM-X60003 52: Secondary air pump valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T8 - OEM-X60004 18: Exhaust flap valve control: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T8 - OEM-X60004 20: Fuel tank leakage diagnostic pump: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T8 - OEM-X60004 30: Fuel tank leakage diagnostic valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T8 - OEM-X60004 4: Cooling fan control: no free low_side/relay_control/heater_low_side/ls_hs/injector on DTAFast T8 - OEM-X60004 17: Engine speed (RPM) output: no free tacho/frequency_out/low_side/ls_hs on DTAFast T8 - OEM-X60004 32: Diagnostic TX (K-line): no free k_line on DTAFast T8 - 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
