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 | 84 wires · 13 connectors · 5 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 |

| 4 | MS3PROEVOHC-C-22 | MS3PROEVOHC-A-13 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 5 | MS3PROEVOHC-A-13 | MS3PROEVOHC-A-8 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 6 | MS3PROEVOHC-A-13 | RLY1-R-OUT | open (OL) | sensor ground must not touch +12 V supply | |
| 7 | MS3PROEVOHC-A-35 | MS3PROEVOHC-A-8 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 8 | MS3PROEVOHC-A-35 | MS3PROEVOHC-C-15 | open (OL) | +12 V supply must not touch 5 V sensor reference | |

| 10 | MS3PROEVOHC-B-3 | MS3PROEVOHC-A-8 | open (OL) | power ground must not touch 5 V sensor reference | |
| 11 | MS3PROEVOHC-B-3 | MS3PROEVOHC-C-15 | open (OL) | power ground must not touch 5 V sensor reference | |
| 12 | MS3PROEVOHC-B-3 | MS3PROEVOHC-C-22 | open (OL) | power ground must not touch 5 V sensor reference | |
| 13 | MS3PROEVOHC-B-3 | RLY1-R-OUT | open (OL) | power ground must not touch +12 V supply | |
| 14 | MS3PROEVOHC-C-15 | RLY1-R-OUT | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 15 | MS3PROEVOHC-C-22 | RLY1-R-OUT | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 16 | RLY1-R-OUT | MS3PROEVOHC-A-8 | 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.

| Severity | Code | Subject | Message |
|---|---|---|---|
| warn | DBW_SHARED_5V | MS3PROEVOHC-C-15 + OEM-A-20 + OEM-E-5 + SP-5V1-1 | These 5 V supplies are separate in the stock car (OEM-A-20 [s2k_vcc2], OEM-E-5 [s2k_vcc3]) and here share one ECU 5 V (MS3PROEVOHC-C-15). On a drive-by-wire car the OEM splits them so one short or fault can't corrupt both throttle/pedal tracks at once. MS3Pro EVO+ HC has 3 5 V sensor supply pin(s). All are in use, so decide: accept the shared supply (and rely on the ECU's DBW fault checks), or add a separate regulated 5 V for the sub tracks. |
| warn | LOAD_UNKNOWN | RLY1-R-OUT | RLY1-R-OUT "Relay contact output (switched +12 V to load)" drives OEM-B-6 VTEC solenoid (load 1.0 A) but its current rating is unknown. Check the ECU manual. |
| warn | SUPPLY_GROUP | MS3PROEVOHC-C-15 + OEM-A-20 + OEM-E-5 + SP-5V1-1 | Supplies meant to stay independent share one net: OEM-A-20 [s2k_vcc2], OEM-E-5 [s2k_vcc3]. The new ECU has no free 5 V reference, so they share one: normal on a standalone, but a short on any of these sensors drops them all. |

| info | NET_FAMILY | OEM-B-21 ↔ MS3PROEVOHC-B-11 | OEM-B-21 "Evap canister purge valve" [low_side_out] is wired to MS3PROEVOHC-B-11 "Injector out G" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |

Notes
Fit check: unconfirmed. Confirm these before building: - Throttle motor draws ≥ ~14 A at stall; peak/stall limit not documented for this ECU (0.75 A continuous rating) - Trigger pattern for Honda F22C1 not found in the ECU's docs (Confirmed absent from documented trigger/decoder list. MS3 "Honda RC51" mode lists the AP1 S2000 only; there is no F22C1/AP2 decoder, and the F22C1 cam trigger (4-1) differs from the AP1/RC51 pattern, so AP2 is not supported.) 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-E 26: Vehicle speed output: no free frequency_out/tacho/low_side/ls_hs on AMP EFI MS3Pro EVO+ HC - OEM-E 16: Power steering load detector: no free analog_0_5 on AMP EFI MS3Pro EVO+ HC - OEM-E 13: Multiplex communication: no free k_line on AMP EFI MS3Pro EVO+ HC - OEM-A 28: A/F sensor signal −: not classified in the library; wire by hand - OEM-A 31: A/F sensor signal +: not classified in the library; wire by hand - OEM-B 10: Alternator L signal: not classified in the library; wire by hand - OEM-B 19: Throttle actuator command to throttle control module (SEFD): not classified in the library; wire by hand - OEM-B 20: Throttle actuator command to throttle control module (SEDF): not classified in the library; wire by hand - OEM-E 27: Immobilizer code: not classified in the library; wire by hand - OEM-E 29: Service check signal: not classified in the library; wire by hand - OEM-E 30: Write enable signal: not classified in the library; wire by hand
