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 | 2: read the Findings page before cutting any wire |
| Size of the job | 69 wires · 10 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 | 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-27 | EMUBLACK-Black-26 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | EMUBLACK-Black-29 | EMUBLACK-Black-26 | open (OL) | sensor ground must not touch 5 V sensor reference |
If any reading doesn't match, stop and get help before powering up.

Findings
Open (10)
| 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. |
| error | REQUIRED_UNMAPPED | OEM-A36-13 | Required OEM function "Injector 4 port (#40)" (injector_out) is not connected to the new ECU. |
| warn | DBW_MOTOR_CURRENT | EMUBLACK-Grey-10 | Cannot confirm EMU Black can drive the throttle motor: EMUBLACK-Grey-10 "H-Bridge #1 Winding B" is rated 6.5 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 | EMUBLACK-Grey-2 | Cannot confirm EMU Black can drive the throttle motor: EMUBLACK-Grey-2 "H-Bridge #1 Winding A" is rated 6.5 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 | OEM-A34-25 ↔ EMUBLACK-Black-20 | OEM-A34-25 "VVT cam sensor exhaust bank 2 (EV2+)" [trigger_in] is wired to EMUBLACK-Black-20 "VSS In" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |
| warn | NET_FAMILY | OEM-A35-5 ↔ EMUBLACK-Grey-11 | OEM-A35-5 "Injector relay (IREL)" [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-A35-7 ↔ EMUBLACK-Grey-3 | OEM-A35-7 "ETCS relay (+BM)" [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 | NO_FUEL_PUMP | fuel pump | This engine harness has no fuel-pump control path: no fuel-pump relay output is wired to the new ECU. If the stock car switches the pump outside the ECU (an airflow-meter contact or a separate module), the standalone must drive the pump relay itself — see the install notes for this car. |
| info | NET_FAMILY | OEM-A36-20 ↔ EMUBLACK-Black-9 | OEM-A36-20 "Oil temperature (OT)" [temp_in] is wired to EMUBLACK-Black-9 "Flex Fuel In" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
