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 | 74 wires · 12 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).
| # | Probe A | Probe B | Expect | Why | Reading |
|---|---|---|---|---|---|
| 1 | G4XSTORMX-A-A5 | G4XSTORMX-A-A24 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | G4XSTORMX-A-A24 | G4XSTORMX-A-A32 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 3 | G4XSTORMX-A-A25 | G4XSTORMX-A-A32 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | G4XSTORMX-A-A25 | G4XSTORMX-A-A5 | open (OL) | power ground must not touch +12 V supply | |
| 5 | G4XSTORMX-A-A5 | G4XSTORMX-A-A32 | 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.

| Severity | Code | Subject | Message |
|---|---|---|---|
| error | DBW_SENSOR_INPUT | tps | Only 0 throttle-position track(s) found. An electronic throttle needs two (main and sub) so the ECU can cross-check them. |

| warn | DBW_SHARED_5V | G4XSTORMX-A-A32 + OEM-D-10 + OEM-F-1 + OEM-F-14 + SP-5V1-1 | These 5 V supplies are separate in the stock car (OEM-D-10 [tps], OEM-F-14 [pedal]) and here share one ECU 5 V (G4XSTORMX-A-A32). On a drive-by-wire car the OEM splits them so one short or fault can't corrupt both throttle/pedal tracks at once. G4X StormX has 1 5 V sensor supply pin(s). All are in use, so decide: accept the shared supply (and rely on the ECU's DBW fault checks), or add a separate regulated 5 V for the sub tracks. |
| warn | LOAD_UNKNOWN | G4XSTORMX-A-A18 | G4XSTORMX-A-A18 "Aux 4" drives OEM-F-4 Fuel pump relay 2 (FLR2) (load 0.2 A) but its current rating is unknown. Check the ECU manual. |
| warn | LOAD_UNKNOWN | G4XSTORMX-A-A21 | G4XSTORMX-A-A21 "Aux 1" drives OEM-A-5 Fuel pump relay (FLR1) (load 0.2 A) but its current rating is unknown. Check the ECU manual. |

| warn | SUPPLY_GROUP | G4XSTORMX-A-A32 + OEM-D-10 + OEM-F-1 + OEM-F-14 + SP-5V1-1 | Supplies meant to stay independent share one net: OEM-D-10 [tps], OEM-F-14 [pedal]. The new ECU has no free 5 V reference, so they share one: normal on a standalone, but a short on any of these sensors drops them all. |

Notes
Fit check: needs add-on. Resolve these before building: - No drive-by-wire; needs a cable-throttle conversion or an external DBW controller - This car has Honda Type 1A (1997+) immobilizer; needs a delete/bypass - Trigger pattern needs a workaround: No C30A/C32B mode in Link docs and no NSX plug-in; community G4X C30A installs reported 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): Link G4X StormX has no battery-constant input; not needed - OEM-A 20: IAB control solenoid (IABCS): no free low_side/relay_control/heater_low_side/ls_hs/injector on Link G4X StormX - OEM-A 21: EVAP purge control solenoid (PCS): no free low_side/relay_control/heater_low_side/ls_hs/injector on Link G4X StormX - OEM-A 4: EVAP canister vent shut valve (VSV): no free low_side/relay_control/heater_low_side/ls_hs/injector on Link G4X StormX - OEM-A 6: EGR control solenoid (ESOL): no free low_side/relay_control/heater_low_side/ls_hs/injector on Link G4X StormX - OEM-A 7: Malfunction indicator lamp (MIL): no free low_side/relay_control/heater_low_side/ls_hs/injector on Link G4X StormX - OEM-C 8: Engine speed pulse (NEP): no free tacho/frequency_out/low_side/ls_hs on Link G4X StormX - OEM-D 20: EGR valve lift sensor (EGRL): no free analog_0_5 on Link G4X StormX - OEM-C 4: Clutch switch (MTCLS, M/T): no free switch_in/frequency_in/analog_0_5 on Link G4X StormX - OEM-C 6: Starter switch (STS): no free switch_in/frequency_in/analog_0_5 on Link G4X StormX - OEM-D 4: K-line diagnostics: no free k_line on Link G4X StormX
