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 | 68 wires · 11 connectors · 4 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. |
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 | SL8-A-34 | SL8-B-10 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | SL8-A-34 | SL8-B-18 | open (OL) | +12 V supply must not touch power ground | |
| 3 | SL8-A-34 | SL8-B-2 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 4 | SL8-B-10 | SL8-B-2 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 5 | SL8-B-18 | SL8-B-2 | open (OL) | power ground must not touch 5 V sensor reference |

| error | REQUIRED_UNMAPPED | OEM-X60003-29 | Required OEM function "Intake camshaft position" (trigger_in) is not connected to the new ECU. |
| warn | DBW_MOTOR_CURRENT | SL8-A-18 | Cannot confirm SL8 can drive the throttle motor: SL8-A-18 "Auxiliary output 9" is rated 5.0 A, but the motor current at OEM-X60003-42 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 | SL8-A-19 | Cannot confirm SL8 can drive the throttle motor: SL8-A-19 "Auxiliary output 10" is rated 5.0 A, but the motor current at OEM-X60003-43 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_ISOLATION | SL8-A-34 | SL8-A-34 "Aux 9–10 14V supply" is fed from the same net as the ECU main supply (SL8-B-1). Link's S2000 DBW wiring feeds the throttle-motor supply through a separate isolation relay switched by the ECU, so motor power can be cut on a throttle fault. Add one, or confirm SL8 cuts the H-bridge internally. |

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (E46 K-bus/CAN); not documented for this ECU - Trigger pattern for BMW S54 not found in the ECU's docs (no BMW S-series trigger pattern named) - This car has EWS 3.3 (rolling code) immobilizer; needs a delete/bypass Auto-mapped by auto_map() from the library pin data on 2026-10-06. Review every wire against both manuals before building. Open items: - OEM-X60003 29: Intake camshaft position: no free cam_hall/cam_vr/frequency_in input on Emtron SL8 Not wired: - OEM-X60001 7: Battery constant (terminal 30): Emtron SL8 has no battery-constant input; not needed - SL8-B 17: Knock 1 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - SL8-B 25: Knock 2 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - OEM-X60003 46: Knock sensor 3: no free knock input on Emtron SL8 - OEM-X60003 47: Knock sensor 4: no free knock input on Emtron SL8 - OEM-X60003 22: Idle speed control, close: no free hbridge on Emtron SL8 - OEM-X60003 23: Idle speed control, open: no free hbridge on Emtron SL8 - SL8-B 4: Ignition switch input: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
