Before you start
| Status | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 60 wires · 9 connectors · 4 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 | EMUBLACK-Black-13 | EMUBLACK-Black-27 | open (OL) | +12 V supply must not touch power ground | |
| 2 | EMUBLACK-Black-13 | EMUBLACK-Black-29 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | EMUBLACK-Black-13 | EMUBLACK-Black-26 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 4 | EMUBLACK-Black-13 | EMUBLACK-Black-34 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 5 | EMUBLACK-Black-27 | EMUBLACK-Black-26 | open (OL) | power ground must not touch 5 V sensor reference | |
| 6 | EMUBLACK-Black-27 | EMUBLACK-Black-34 | open (OL) | power ground must not touch 5 V sensor reference | |
| 7 | EMUBLACK-Black-29 | EMUBLACK-Black-26 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 8 | EMUBLACK-Black-29 | EMUBLACK-Black-34 | open (OL) | sensor ground must not touch 5 V sensor reference |

| warn | NET_FAMILY | OEM-A-12 ↔ EMUBLACK-Grey-2 | OEM-A-12 "Immobilizer indicator light" [low_side_out] is wired to EMUBLACK-Grey-2 "H-Bridge #1 Winding A" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-18 ↔ EMUBLACK-Grey-11 | OEM-A-18 "Check engine light (MIL)" [low_side_out] is wired to EMUBLACK-Grey-11 "H-Bridge #2 Winding B" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-2 ↔ EMUBLACK-Grey-3 | OEM-A-2 "Air control valve solenoid" [low_side_out] is wired to EMUBLACK-Grey-3 "H-Bridge #2 Winding A" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-B-12 ↔ EMUBLACK-Grey-10 | OEM-B-12 "VTEC solenoid" [high_side_out] is wired to EMUBLACK-Grey-10 "H-Bridge #1 Winding B" [hbridge_out]. A half-bridge can act as a high-side switch only if configured that way. |
| info | NET_FAMILY | OEM-A-1 ↔ EMUBLACK-Grey-22 | OEM-A-1 "Coolant temp gauge drive" [low_side_out] is wired to EMUBLACK-Grey-22 "Injector #6" [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 2026-10-06. Review every wire against both manuals before building. Not wired: - OEM-B 21: Backup power (battery constant): ECUMASTER EMU Black has no battery-constant input; not needed - OEM-C 22: Knock sensor: 2 stock pins named "Knock sensor" without a documented polarity / pairing; wire by hand - OEM-C 3: Knock sensor: 2 stock pins named "Knock sensor" without a documented polarity / pairing; wire by hand - OEM-A 3: Evap bypass solenoid: no free low_side/ls_hs/injector/hbridge on ECUMASTER EMU Black - OEM-A 4: Evap canister vent shut valve: no free low_side/ls_hs/injector/hbridge on ECUMASTER EMU Black - OEM-A 6: Evap canister purge valve: no free low_side/ls_hs/injector/hbridge on ECUMASTER EMU Black - OEM-C 2: Alternator control: no free low_side/ls_hs/injector/hbridge on ECUMASTER EMU Black - OEM-A 19: Tacho output: no free tacho/frequency_out/low_side/ls_hs on ECUMASTER EMU Black - OEM-A 27: A/C switch (request): no free switch_in/frequency_in/analog_0_5 on ECUMASTER EMU Black - OEM-A 32: Brake switch: no free switch_in/frequency_in/analog_0_5 on ECUMASTER EMU Black - OEM-C 10: VTEC pressure switch: no free switch_in/frequency_in/analog_0_5 on ECUMASTER EMU Black - OEM-A 21: K-Line: no free k_line on ECUMASTER EMU Black - OEM-A 10: Service check signal: not classified in the library; wire by hand - OEM-A 13: Immobilizer enable signal: not classified in the library; wire by hand - OEM-A 25: Immobilizer code: not classified in the library; wire by hand - EMUBLACK-Grey 18: Ignition +12V: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
