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 | 85 wires · 12 connectors · 5 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).

Notes
Fit check: unconfirmed. Confirm these before building: - Throttle motor draws ≥ ~14 A at stall; peak/stall limit not documented for this ECU (12.0 A continuous rating) Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Not wired: - OEM-E 9: Ignition signal: key-on 12 V sense — optional in a swap (the main relay is energized from keyed 12 V, not from this pin); MoTeC M190 has no dedicated key-on input - OEM-E 25: Engine speed pulse (tacho): no free tacho/frequency_out/low_side/ls_hs on MoTeC M190 - OEM-E 26: Vehicle speed output: no free frequency_out/tacho/low_side/ls_hs on MoTeC M190 - OEM-E 13: Multiplex communication: no free k_line on MoTeC M190 - OEM-A 28: A/F sensor signal −: not classified in the library; wire by hand - OEM-A 31: A/F sensor signal +: not classified in the library; wire by hand - OEM-B 10: Alternator L signal: not classified in the library; wire by hand - OEM-B 19: Throttle actuator command to throttle control module (SEFD): not classified in the library; wire by hand - OEM-B 20: Throttle actuator command to throttle control module (SEDF): not classified in the library; wire by hand - OEM-E 27: Immobilizer code: not classified in the library; wire by hand - OEM-E 29: Service check signal: not classified in the library; wire by hand - OEM-E 30: Write enable signal: not classified in the library; wire by hand
