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 | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 70 wires · 10 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 | MS3PROEVO-A-35 | MS3PROEVO-A-13 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | MS3PROEVO-A-35 | MS3PROEVO-B-3 | open (OL) | +12 V supply must not touch power ground | |
| 3 | MS3PROEVO-A-8 | MS3PROEVO-A-13 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 4 | MS3PROEVO-A-8 | MS3PROEVO-B-3 | open (OL) | 5 V sensor reference must not touch power ground | |
| 5 | MS3PROEVO-A-8 | MS3PROEVO-A-35 | 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.

| Severity | Code | Subject | Message |
|---|---|---|---|
| warn | NET_FAMILY | MS3PROEVO-A-15 ↔ MS3PROEVO-B-35 | MS3PROEVO-A-15 "CKP−" [trigger_in] is wired to MS3PROEVO-B-35 "Digital Frequency in 1 (VR−)" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| warn | NET_FAMILY | OEM-C-1 ↔ MS3PROEVO-A-23 | OEM-C-1 "TPS idle switch (IDL)" [digital_in] is wired to MS3PROEVO-A-23 "Analog In 5" [analog_in]. Analog and digital on one net. A switch on an analog input works with a pull-up and a threshold; an analog sensor on a digital input loses its value. |
| warn | NET_FAMILY | OEM-C-6 ↔ MS3PROEVO-B-34 | OEM-C-6 "Cam sensor 2 + (G2+)" [trigger_in] is wired to MS3PROEVO-B-34 "Digital Frequency in 1 (VR+)" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| info | NET_FAMILY | MS3PROEVO-A-27 ↔ MS3PROEVO-C-19 | MS3PROEVO-A-27 "CMP−" [trigger_in] is wired to MS3PROEVO-C-19 "Sensor return" [sensor_ground]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | MS3PROEVO-B-35 ↔ MS3PROEVO-C-17 | MS3PROEVO-B-35 "Digital Frequency in 1 (VR−)" [digital_in] is wired to MS3PROEVO-C-17 "Sensor return" [sensor_ground]. A digital input used as a ground/identification strap (e.g. AT/MT ID is grounded on manual cars) is compatible with a sensor ground. |
| info | NET_FAMILY | OEM-A-7 ↔ MS3PROEVO-A-22 | OEM-A-7 "EGR temperature sensor" [temp_in] is wired to MS3PROEVO-A-22 "Analog In 4" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-B-8 ↔ MS3PROEVO-B-11 | OEM-B-8 "Fuel pump control (FC)" [low_side_out] is wired to MS3PROEVO-B-11 "Injector out G" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-D-21 ↔ MS3PROEVO-B-12 | OEM-D-21 "EGR solenoid" [low_side_out] is wired to MS3PROEVO-B-12 "Injector out H" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-D-22 ↔ MS3PROEVO-B-2 | OEM-D-22 "Fuel pressure-up VSV (PR)" [low_side_out] is wired to MS3PROEVO-B-2 "Injector out B" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-D-4 ↔ MS3PROEVO-B-4 | OEM-D-4 "Cold start injector (STJ)" [low_side_out] is wired to MS3PROEVO-B-4 "Injector out C" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |

Notes
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-B 26: Battery constant (BATT): AMP EFI MS3Pro EVO+ has no battery-constant input; not needed - OEM-A 8: Knock/shield (KS): no free knock input on AMP EFI MS3Pro EVO+ - OEM-C 4: Check connector VF1: no free analog_out on AMP EFI MS3Pro EVO+ - OEM-C 12: Check connector VF2: no free analog_out on AMP EFI MS3Pro EVO+
