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 | 82 wires · 14 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).
| # | Probe A | Probe B | Expect | Why | Reading |
|---|---|---|---|---|---|
| 1 | KV8-D-1 | KV8-C-17 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | KV8-B-34 | KV8-D-1 | open (OL) | power ground must not touch +12 V supply | |
| 3 | KV8-B-34 | KV8-D-21 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | KV8-B-34 | KV8-D-22 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | KV8-C-17 | KV8-D-21 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 6 | KV8-C-17 | KV8-D-22 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 7 | KV8-D-1 | KV8-D-21 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 8 | KV8-D-1 | KV8-D-22 | 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: - Trigger pattern for Honda C32B not found in the ECU's docs (No C32B/NSX decoder.) - 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-D 1: Backup power (VBU): Emtron KV8 has no battery-constant input; not needed - OEM-B 7: Crank position sensor 2 + (CKP 2P): no free crank_vr/frequency_in input on Emtron KV8 - OEM-B 5: Cylinder position sensor 2 + (CYP 2P): no free cam_vr/cam_hall/frequency_in input on Emtron KV8 - KV8-D 12: Knock 1 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - KV8-D 18: Knock 2 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - OEM-A 6: EGR control solenoid (ESOL): no free low_side/relay_control/heater_low_side/ls_hs/injector on Emtron KV8 - OEM-A 7: Malfunction indicator lamp (MIL): no free low_side/relay_control/heater_low_side/ls_hs/injector on Emtron KV8 - OEM-C 8: Engine speed pulse (NEP): no free tacho/frequency_out/low_side/ls_hs on Emtron KV8 - OEM-D 4: K-line diagnostics: no free k_line on Emtron KV8 - KV8-D 15: Ignition switch input: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
