Before you start
| 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 | 70 wires · 11 connectors · 3 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |
| Terminals | 3-1447221-4 |
| 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. |

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 | SHADOW8-A-1 | SHADOW8-A-4 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | SHADOW8-A-1 | SHADOW8-A-3 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 3 | SHADOW8-A-34 | SHADOW8-A-1 | open (OL) | power ground must not touch +12 V supply | |
| 4 | SHADOW8-A-34 | SHADOW8-A-3 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | SHADOW8-A-34 | SHADOW8-B-1 | open (OL) | power ground must not touch +12 V supply | |
| 6 | SHADOW8-A-4 | SHADOW8-A-3 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 7 | SHADOW8-A-4 | SHADOW8-B-1 | open (OL) | sensor ground must not touch +12 V supply | |
| 8 | SHADOW8-B-1 | SHADOW8-A-3 | open (OL) | +12 V supply must not touch 5 V sensor reference |

| error | PHYS_REQUIRED_OPEN | SHADOW8-B-21 | SHADOW8-B-21 "Digital input 10 / ignition switch" is required but not wired. |
| warn | NET_FAMILY | OEM-A-14 ↔ SHADOW8-B-22 | OEM-A-14 "Chamber volume control solenoid (BPS)" [low_side_out] is wired to SHADOW8-B-22 "Aux output 9" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-20 ↔ SHADOW8-B-23 | OEM-A-20 "EVAP purge cut-off solenoid (PGS)" [low_side_out] is wired to SHADOW8-B-23 "Aux output 10" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-9 ↔ SHADOW8-B-24 | OEM-A-9 "Idle air control valve (IACV)" [low_side_out] is wired to SHADOW8-B-24 "Aux output 11" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-C-9 ↔ SHADOW8-A-20 | OEM-C-9 "Service check connector (SCS)" [digital_in] is wired to SHADOW8-A-20 "Analog voltage 8 (switchable 1k pull-up)" [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-D-8 ↔ SHADOW8-A-21 | OEM-D-8 "Ignition timing adjuster (IGADJ)" [digital_in] is wired to SHADOW8-A-21 "Analog voltage 9 (switchable 1k pull-up)" [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-5-F5 ↔ SHADOW8-B-14 | OEM-5-F5 "Front VTEC solenoid valve" [high_side_out] is wired to SHADOW8-B-14 "Aux output 5" [switch_out]. Configure this output as high side. |
| info | NET_FAMILY | OEM-5-F7 ↔ SHADOW8-B-15 | OEM-5-F7 "Rear VTEC solenoid valve" [high_side_out] is wired to SHADOW8-B-15 "Aux output 6" [switch_out]. Configure this output as high side. |
| info | NET_FAMILY | OEM-A-10 ↔ SHADOW8-B-16 | OEM-A-10 "Front O2 sensor heater (HTCNTF)" [low_side_out] is wired to SHADOW8-B-16 "Aux output 7" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-A-11 ↔ SHADOW8-B-8 | OEM-A-11 "EGR control solenoid" [low_side_out] is wired to SHADOW8-B-8 "Injector cylinder 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-12 ↔ SHADOW8-B-17 | OEM-A-12 "Rear O2 sensor heater (HTCNTR)" [low_side_out] is wired to SHADOW8-B-17 "Aux output 8" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-A-13 ↔ SHADOW8-B-9 | OEM-A-13 "Check engine light (WARN)" [low_side_out] is wired to SHADOW8-B-9 "Injector cylinder 8" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-D-13 ↔ SHADOW8-A-14 | OEM-D-13 "Engine coolant temperature (ECT)" [temp_in] is wired to SHADOW8-A-14 "Analog voltage 5" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-D-15 ↔ SHADOW8-A-18 | OEM-D-15 "Intake air temperature (IAT)" [temp_in] is wired to SHADOW8-A-18 "Analog voltage 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |

Notes
Fit check: unconfirmed. Confirm these before building: - Trigger pattern for Honda C30A not found in the ECU's docs (Emtron decoder list has no C30A/C32B/NSX (Honda K20/K24/F20C/F22C, Subaru EJ, Mazda MX5 only)) Auto-mapped by auto_map() from the library pin data on 2026-10-06. Review every wire against both manuals before building. Open items: - SHADOW8-B 21: Digital input 10 / ignition switch: required by Emtron Shadow 8 but no stock pin feeds it; wire by hand Not wired: - OEM-B 13: CRNK 2P — TDC sensor signal: no free crank_vr/frequency_in input on Emtron Shadow 8 - OEM-B 9: CYL 2P — CYP sensor 2 signal: no free cam_vr/cam_hall/frequency_in input on Emtron Shadow 8 - SHADOW8-A 17: Knock 1 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - SHADOW8-A 25: Knock 2 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - OEM-C 4: Tachometer output (NEP): no free tacho/frequency_out/low_side/ls_hs on Emtron Shadow 8 - 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
