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 | 4: read the Findings page before cutting any wire |
| Size of the job | 48 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).

| Severity | Code | Subject | Message |
|---|---|---|---|
| error | INJECTOR_BALLAST | G4X MonsoonX | The 2JZ-GTE injectors (2JZ-GTE fuel injector) are low-impedance, but G4X MonsoonX drives saturated (high-Z) injectors only. Add a ballast resistor pack in series with each injector, or use an ECU with low-Z / peak-and-hold injector drivers. |

| warn | LOAD_UNKNOWN | G4XMONSOONX-A-A26 | G4XMONSOONX-A-A26 "Aux 6" drives OEM-B78-10 EFI main relay control (M-REL) (load 0.2 A) but its current rating is unknown. Check the ECU manual. |
| warn | LOAD_UNKNOWN | G4XMONSOONX-A-A27 | G4XMONSOONX-A-A27 "Aux 5" drives OEM-B77-13 A/C clutch relay (ACMG) (load 0.2 A) but its current rating is unknown. Check the ECU manual. |
| warn | NO_FUEL_PUMP | fuel pump | This engine harness has no fuel-pump control path: no fuel-pump relay output is wired to the new ECU. If the stock car switches the pump outside the ECU (an airflow-meter contact or a separate module), the standalone must drive the pump relay itself — see the install notes for this car. |

Notes
Fit check: needs add-on. Resolve these before building: - Drive-by-wire only with an add-on: Link RET 115-1000 - Low-impedance injectors need a ballast resistor pack in series with each injector, or an ECU with low-Z / peak-and-hold injector drivers - Trigger pattern for Toyota 2JZ-GTE not found in the ECU's docs (Link's trigger-mode list is only inside PCLink, not online) - Only 4 ignition outputs for 6 cylinders: wasted spark (pair coils per firing order) - Only 4 injector outputs for 6 injectors: batch / semi-sequential injection Auto-mapped by auto_map() from the library pin data on 2026-10-20. Review every wire against both manuals before building. Open items: - OEM-B74 7: ETCS-i motor − (M−): needs a paired H-bridge on Link G4X MonsoonX (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) - OEM-B74 8: ETCS-i motor + (M+): needs a paired H-bridge on Link G4X MonsoonX (H-bridge pairing not in the library: set device_pin.bridge_pair from the ECU manual) -
