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 | 3: read the Findings page before cutting any wire |
| Size of the job | 62 wires · 11 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 | M800-A-26 | M800-A-10 | open (OL) | +12 V supply must not touch power ground | |
| 2 | M800-A-26 | M800-B-14 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | M800-A-10 | M800-A-2 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | M800-A-26 | M800-A-2 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 5 | M800-B-14 | M800-A-2 | open (OL) | sensor ground 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: - Drive-by-wire only with an add-on: MoTeC DBW4 expander (obsolete) - 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 - Trigger pattern for BMW S54 not checked yet Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Open items: - OEM-X60003 29: Intake camshaft position: no free cam_hall/cam_vr/frequency_in input on MoTeC M800 - OEM-X60003 42: Throttle motor drive 1 (H-bridge): no free hbridge on MoTeC M800 - OEM-X60003 43: Throttle motor drive 2 (H-bridge): no free hbridge on MoTeC M800 Not wired: - OEM-X60001 7: Battery constant (terminal 30): MoTeC M800 has no battery-constant input; not needed - OEM-X60003 33: Knock sensor 1: no free knock input on MoTeC M800 - OEM-X60003 34: Knock sensor 2: no free knock input on MoTeC M800 - OEM-X60003 46: Knock sensor 3: no free knock input on MoTeC M800 - OEM-X60003 47: Knock sensor 4: no free knock input on MoTeC M800 - OEM-X60003 22: Idle speed control, close: no free hbridge on MoTeC M800 - OEM-X60003 23: Idle speed control, open: no free hbridge on MoTeC M800 - OEM-X60003 9: VANOS exhaust solenoid: no free low_side/ls_hs/injector/hbridge on MoTeC M800
