Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 75 wires · 12 connectors · 1 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 | G4XXTREMEX-A-A5 | G4XXTREMEX-A-A24 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | G4XXTREMEX-A-A24 | G4XXTREMEX-A-A32 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 3 | G4XXTREMEX-A-A25 | G4XXTREMEX-A-A32 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | G4XXTREMEX-A-A25 | G4XXTREMEX-A-A5 | open (OL) | power ground must not touch +12 V supply | |
| 5 | G4XXTREMEX-A-A5 | G4XXTREMEX-A-A32 | open (OL) | +12 V supply must not touch 5 V sensor reference |

| Severity | Code | Subject | Message |
|---|---|---|---|
| warn | DBW_MOTOR_CURRENT | G4XXTREMEX-B-B18 | Cannot confirm G4X XtremeX can drive the throttle motor: neither the motor current (OEM-X60003-43) nor the rating of G4XXTREMEX-B-B18 "Aux 9" is known. |
| warn | DBW_MOTOR_CURRENT | G4XXTREMEX-B-B26 | Cannot confirm G4X XtremeX can drive the throttle motor: neither the motor current (OEM-X60003-44) nor the rating of G4XXTREMEX-B-B26 "Aux 10" is known. |
| warn | DBW_MOTOR_ISOLATION | G4XXTREMEX-B-B5 | G4XXTREMEX-B-B5 "Aux 9/10 E-Throttle Supply" is fed from the same net as the ECU main supply (G4XXTREMEX-A-A5). 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 G4X XtremeX cuts the H-bridge internally. |
| warn | NET_FAMILY | OEM-X60003-5 ↔ G4XXTREMEX-A-A30 | OEM-X60003-5 "Intake camshaft position" [trigger_in] is wired to G4XXTREMEX-A-A30 "Digital Input 1" [digital_in]. Hall-type cam/speed signals can use a digital input if it handles the frequency; VR signals cannot. |

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (E46 K-bus/CAN); not documented for this ECU - 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. Not wired: - OEM-X60001 7: Battery constant (terminal 30): Link G4X XtremeX has no battery-constant input; not needed - OEM-X60003 31: Knock sensor, cylinders 4-6 (A): no free knock input on Link G4X XtremeX - OEM-X60003 32: Knock sensor, cylinders 4-6 (B): no free knock input on Link G4X XtremeX - OEM-X60003 46: Idle speed control, close: no free hbridge on Link G4X XtremeX - OEM-X60003 47: Idle speed control, open: no free hbridge on Link G4X XtremeX - OEM-X60003 45: Map-controlled thermostat: no free low_side/ls_hs/injector/hbridge on Link G4X XtremeX - OEM-X60003 49: DISA intake flap: no free low_side/ls_hs/injector/hbridge on Link G4X XtremeX
