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 | 97 wires · 12 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 | MS3PROEVOHC-A-35 | MS3PROEVOHC-A-13 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | MS3PROEVOHC-A-35 | MS3PROEVOHC-B-3 | open (OL) | +12 V supply must not touch power ground | |
| 3 | MS3PROEVOHC-A-13 | MS3PROEVOHC-A-8 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 4 | MS3PROEVOHC-A-35 | MS3PROEVOHC-A-8 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 5 | MS3PROEVOHC-B-3 | MS3PROEVOHC-A-8 | open (OL) | power ground must not touch 5 V sensor reference |
If any reading doesn't match, stop and get help before powering up.

| Severity | Code | Subject | Message |
|---|---|---|---|
| error | DBW_SENSOR_INPUT | tps | Only 1 throttle-position track(s) found. An electronic throttle needs two (main and sub) so the ECU can cross-check them. |
| warn | DBW_MOTOR_CURRENT | MS3PROEVOHC-B-30 | Cannot confirm MS3Pro EVO+ HC can drive the throttle motor: MS3PROEVOHC-B-30 "Stepper IAC out 1B" is rated 0.75 A, but the motor current at OEM-A36-1 is unknown. Add the motor's peak current from a source, or measure the motor resistance: peak ≈ 14 V ÷ R (Hondata measured 4.9 A for a Civic Si body, 10.4 A for a ZDX body; holding current is about 1 A). |
| warn | DBW_MOTOR_CURRENT | MS3PROEVOHC-B-31 | Cannot confirm MS3Pro EVO+ HC can drive the throttle motor: MS3PROEVOHC-B-31 "Stepper IAC out 1A" is rated 0.75 A, but the motor current at OEM-A36-2 is unknown. Add the motor's peak current from a source, or measure the motor resistance: peak ≈ 14 V ÷ R (Hondata measured 4.9 A for a Civic Si body, 10.4 A for a ZDX body; holding current is about 1 A). |
| warn | NET_FAMILY | MS3PROEVOHC-A-15 ↔ MS3PROEVOHC-B-35 | MS3PROEVOHC-A-15 "CKP−" [trigger_in] is wired to MS3PROEVOHC-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-A34-13 ↔ MS3PROEVOHC-B-33 | OEM-A34-13 "High-pressure fuel pump spill valve (FPF)" [low_side_out] is wired to MS3PROEVOHC-B-33 "Stepper IAC out 2B" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A34-15 ↔ MS3PROEVOHC-B-17 | OEM-A34-15 "VVT cam sensor intake bank 2 (VV2+)" [trigger_in] is wired to MS3PROEVOHC-B-17 "Digital frequency in 2 (Hall)" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| warn | NET_FAMILY | OEM-A34-25 ↔ MS3PROEVOHC-B-28 | OEM-A34-25 "VVT cam sensor exhaust bank 2 (EV2+)" [trigger_in] is wired to MS3PROEVOHC-B-28 "Digital frequency in 1 (unconditioned)" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| warn | NET_FAMILY | OEM-A34-26 ↔ MS3PROEVOHC-B-34 | OEM-A34-26 "VVT cam sensor intake bank 1 (VV1+)" [trigger_in] is wired to MS3PROEVOHC-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. |
| warn | NET_FAMILY | OEM-A36-5 ↔ MS3PROEVOHC-B-32 | OEM-A36-5 "OCV exhaust bank 2 (OE2)" [low_side_out] is wired to MS3PROEVOHC-B-32 "Stepper IAC out 2A" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| info | NET_FAMILY | MS3PROEVOHC-A-15 ↔ MS3PROEVOHC-C-19 | MS3PROEVOHC-A-15 "CKP−" [trigger_in] is wired to MS3PROEVOHC-C-19 "Sensor return" [sensor_ground]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | MS3PROEVOHC-B-35 ↔ MS3PROEVOHC-C-20 | MS3PROEVOHC-B-35 "Digital Frequency in 1 (VR−)" [digital_in] is wired to MS3PROEVOHC-C-20 "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-A36-16 ↔ MS3PROEVOHC-B-8 | OEM-A36-16 "OCV intake bank 2 (OC2)" [low_side_out] is wired to MS3PROEVOHC-B-8 "Injector out E" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A36-20 ↔ MS3PROEVOHC-A-12 | OEM-A36-20 "Oil temperature (OT)" [temp_in] is wired to MS3PROEVOHC-A-12 "Analog In 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-A36-7 ↔ MS3PROEVOHC-B-6 | OEM-A36-7 "OCV exhaust bank 1 (OE1)" [low_side_out] is wired to MS3PROEVOHC-B-6 "Injector out D" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
