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 | 5: read the Findings page before cutting any wire |
| Size of the job | 86 wires · 13 connectors · 0 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: - Trigger pattern for Honda C32B not found in the ECU's docs (M150 engine-speed modes (datasheet 23514) list CBR250RR/F20C/J35A/K20/K20C1/K24AZ7/L15B7 — no C30A/C32B/NSX) - This car has Honda Type 1A (1997+) immobilizer; needs a delete/bypass 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-G 4: Throttle motor phase 1 (PM1): no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-G 5: Throttle motor phase 2 (PM2): no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-G 11: Throttle motor phase 3 (PM3): no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-G 12: Throttle motor phase 4 (PM4): no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand Not wired: - OEM-A 4: EVAP canister vent shut valve (VSV): no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M150 - OEM-A 6: EGR control solenoid (ESOL): no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M150 - OEM-A 7: Malfunction indicator lamp (MIL): no free low_side/relay_control/heater_low_side/ls_hs/injector on MoTeC M150 - OEM-C 8: Engine speed pulse (NEP): no free tacho/frequency_out/low_side/ls_hs on MoTeC M150 - OEM-D 4: K-line diagnostics: no free k_line on MoTeC M150
