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 | 39 wires · 6 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 | G4XATOMX-A-A32 | G4XATOMX-A-A24 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 2 | G4XATOMX-A-A5 | G4XATOMX-A-A24 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | G4XATOMX-A-A5 | G4XATOMX-A-A25 | open (OL) | +12 V supply must not touch power ground | |
| 4 | G4XATOMX-A-A25 | G4XATOMX-A-A32 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | G4XATOMX-A-A5 | G4XATOMX-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.

| error | INJECTOR_BALLAST | G4X AtomX | The 2JZ-GTE injectors (2JZ-GTE fuel injector) are low-impedance, but G4X AtomX 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 | G4XATOMX-A-A20 | G4XATOMX-A-A20 "Aux 2" drives OEM-E10-24 Main relay control (M-REL) (load 0.2 A) but its current rating is unknown. Check the ECU manual. |
| warn | LOAD_UNKNOWN | G4XATOMX-A-A21 | G4XATOMX-A-A21 "Aux 1" drives OEM-E10-23 A/C clutch relay (ACMG) (load 0.2 A) but its current rating is unknown. Check the ECU manual. |
| warn | NET_FAMILY | OEM-E9-25 ↔ G4XATOMX-A-A30 | OEM-E9-25 "Camshaft position 2 (G2)" [trigger_in] is wired to G4XATOMX-A-A30 "Digital Input 1" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| 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. |
