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 | none |
| Size of the job | 68 wires · 9 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 | PROTEUS-Black23-12 | PROTEUS-Black23-23 | open (OL) | sensor ground must not touch +12 V supply | |
| 2 | PROTEUS-Black23-12 | PROTEUS-White35-10 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 3 | PROTEUS-Black23-14 | PROTEUS-Black23-23 | open (OL) | power ground must not touch +12 V supply | |
| 4 | PROTEUS-Black23-14 | PROTEUS-White35-10 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | PROTEUS-White35-10 | PROTEUS-Black23-23 | open (OL) | 5 V sensor reference must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

| info | NET_FAMILY | OEM-A-1C ↔ PROTEUS-Black35-5 | OEM-A-1C "Idle speed control (ISC) solenoid" [low_side_out] is wired to PROTEUS-Black35-5 "Injector 5" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-1E ↔ PROTEUS-Black35-6 | OEM-A-1E "Turbo charge control solenoid" [low_side_out] is wired to PROTEUS-Black35-6 "Injector 6" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-1G ↔ PROTEUS-Black35-7 | OEM-A-1G "Purge solenoid" [low_side_out] is wired to PROTEUS-Black35-7 "Injector 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-1I ↔ PROTEUS-Black35-19 | OEM-A-1I "Turbo charge relief solenoid" [low_side_out] is wired to PROTEUS-Black35-19 "Injector 8" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-1K ↔ PROTEUS-Black35-8 | OEM-A-1K "Turbo pre-control solenoid" [low_side_out] is wired to PROTEUS-Black35-8 "Injector 9" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | PROTEUS-White35-3 ↔ PROTEUS-Black23-13 | PROTEUS-White35-3 "Sensor ground" [sensor_ground] is wired to PROTEUS-Black23-13 "VR 1 negative" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | UNMAPPED | OEM | 4 optional OEM pins are not mapped: OEM-A-1M Turbo control solenoid; OEM-A-1O Boost control solenoid; OEM-C-3G Fuel pressure regulator control (PRC) solenoid; OEM-D-4M Tachometer output |

Notes
Fit check: needs add-on. Resolve these before building: - Sequential twin-turbo control needed; not documented for this ECU Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Not wired: - OEM-D 4B: Battery constant (+12V): rusEFI Proteus has no battery-constant input; not needed - OEM-A 1M: Turbo control solenoid: no free low_side/ls_hs/injector/hbridge on rusEFI Proteus - OEM-A 1O: Boost control solenoid: no free low_side/ls_hs/injector/hbridge on rusEFI Proteus - OEM-C 3G: Fuel pressure regulator control (PRC) solenoid: no free low_side/ls_hs/injector/hbridge on rusEFI Proteus - OEM-D 4M: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on rusEFI Proteus
