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 | 1: read the Findings page before cutting any wire |
| Size of the job | 32 wires · 11 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 | MAIN-R-COIL- | MAIN-R-OUT | open (OL) | power ground must not touch +12 V supply | |
| 2 | MAIN-R-COIL- | NEW-BATT-1 | open (OL) | power ground must not touch +12 V supply | |
| 3 | MAIN-R-COIL- | NEW-KEYON-1 | open (OL) | power ground must not touch +12 V supply | |
| 4 | PROTEUS-White35-1 | MAIN-R-OUT | open (OL) | sensor ground must not touch +12 V supply | |
| 5 | PROTEUS-White35-1 | NEW-BATT-1 | open (OL) | sensor ground must not touch +12 V supply | |
| 6 | PROTEUS-White35-1 | NEW-KEYON-1 | open (OL) | sensor ground must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

| error | INJECTOR_BALLAST | Proteus | The 7M-GTE injectors (7M-GTE fuel injector) are low-impedance, but Proteus 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 | 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. |
| info | NET_FAMILY | PROTEUS-Black23-18 ↔ MAIN-R-COIL+ | PROTEUS-Black23-18 "Ignition switch in" [digital_in] is wired to MAIN-R-COIL+ "Relay coil positive (ignition-switched +12V)" [power_in]. Switched supply used as the ignition-on sense. |

Notes
Fit check: needs add-on. Resolve these before building: - 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 7M-GTE not found in the ECU's docs (Confirmed absent from documented trigger/decoder list. The 7M-GTE uses a Nippondenso CAS (Ne=24 + G1/G2). rusEFI has no 24+1/24+2 Nippondenso CAS decoder; Toyota modes are 2JZ 12-tooth, 3-tooth UZ, VVT Toyota 4-1/3-tooth and 36-2-2-2 onl...) Auto-mapped by auto_map() from the library pin data on 2026-10-20. Review every wire against both manuals before building. Open items: - Main-relay feed: no switched power (ecu_main_power / switched_feed) on the stock ECU - Fuel-pump control: rusEFI Proteus needs to drive the fuel pump, but the stock ECU has no fuel-pump output (an airflow-meter contact or a separate module runs it) and the ECU has no fuel-pump output pin to wire — add a fuel-pump relay on a spare low-side output, see the install notes for this car.
