Before you start

Status	draft · not yet verified: nobody has reported building and running this harness
Open errors	none
Size of the job	83 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
1	PROTEUS-Black23-23	PROTEUS-Black23-12	open (OL)	+12 V supply must not touch sensor ground
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-Black23-23	PROTEUS-White35-10	open (OL)	+12 V supply must not touch 5 V sensor reference

Severity	Code	Subject	Message
warn	NET_FAMILY	OEM-A-9 ↔ PROTEUS-Black23-6	OEM-A-9 "Idle air control valve (IACV)" [low_side_out] is wired to PROTEUS-Black23-6 "ETB 1 negative" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way.
warn	NET_FAMILY	OEM-B-13 ↔ PROTEUS-Black23-2	OEM-B-13 "CRNK 2P — TDC sensor signal" [trigger_in] is wired to PROTEUS-Black23-2 "Digital 3" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot.
warn	NET_FAMILY	OEM-B-7 ↔ PROTEUS-White35-26	OEM-B-7 "Neutral switch (M/T) / gear position (A/T)" [digital_in] is wired to PROTEUS-White35-26 "Analog Volt 6" [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-11 ↔ PROTEUS-White35-16	OEM-C-11 "Starter switch (STS)" [digital_in] is wired to PROTEUS-White35-16 "Analog Volt 7" [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-3 ↔ PROTEUS-White35-27	OEM-C-3 "A/C switch (ACS)" [digital_in] is wired to PROTEUS-White35-27 "Analog Volt 8" [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-5 ↔ PROTEUS-White35-17	OEM-C-5 "A/C pressure switch (PDSW)" [digital_in] is wired to PROTEUS-White35-17 "Analog Volt 9" [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-7 ↔ PROTEUS-White35-28	OEM-C-7 "Clutch switch (M/T)" [digital_in] is wired to PROTEUS-White35-28 "Analog Volt 10" [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-9 ↔ PROTEUS-White35-18	OEM-C-9 "Service check connector (SCS)" [digital_in] is wired to PROTEUS-White35-18 "Analog Volt 11" [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.
info	NET_FAMILY	OEM-A-13 ↔ PROTEUS-Black35-7	OEM-A-13 "Check engine light (WARN)" [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-14 ↔ PROTEUS-Black35-19	OEM-A-14 "Chamber volume control solenoid (BPS)" [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-20 ↔ PROTEUS-Black35-8	OEM-A-20 "EVAP purge cut-off solenoid (PGS)" [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-White35-4 ↔ PROTEUS-Black23-12	PROTEUS-White35-4 "Sensor ground" [sensor_ground] is wired to PROTEUS-Black23-12 "VR 2 negative" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs.
info	UNMAPPED	OEM	8 optional OEM pins are not mapped: OEM-C-10 Traction control; OEM-C-12 Traction control; OEM-C-4 Tachometer output (NEP); OEM-C-6 Traction control; OEM-C-8 Traction control; OEM-D-5 Traction control; OEM-D-6 Fuel pump voltage monitor (VFP); OEM-D-8 Ignition timing adjuster (IGADJ)

Notes

Fit check: unconfirmed. Confirm these before building: - Trigger pattern for Honda C30A not found in the ECU's docs (All-Supported-Triggers Honda = CBR600 / K crank 12+1 / K cam 4+1 / J30A2 24+1+1 — no C30A/C32B/NSX) Auto-mapped by auto_map() from the library pin data on 2026-10-06. Review every wire against both manuals before building. Not wired: - OEM-D 1: Battery backup (VBU): rusEFI Proteus has no battery-constant input; not needed - OEM-C 4: Tachometer output (NEP): no free tacho/frequency_out/low_side/ls_hs on rusEFI Proteus - OEM-D 8: Ignition timing adjuster (IGADJ): no free switch_in/frequency_in/analog_0_5 on rusEFI Proteus - OEM-C 10: Traction control: not classified in the library; wire by hand - OEM-C 12: Traction control: not classified in the library; wire by hand - OEM-C 6: Traction control: not classified in the library; wire by hand - OEM-C 8: Traction control: not classified in the library; wire by hand - OEM-D 5: Traction control: not classified in the library; wire by hand - OEM-D 6: Fuel pump voltage monitor (VFP): not classified in the library; wire by hand - PROTEUS-Black23 18: Ignition switch in: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
