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 | none |
| Size of the job | 73 wires · 11 connectors · 5 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-A32 | G4XXTREMEX-A-A24 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 2 | G4XXTREMEX-A-A5 | G4XXTREMEX-A-A24 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | G4XXTREMEX-A-A5 | G4XXTREMEX-A-A25 | open (OL) | +12 V supply must not touch power ground | |
| 4 | G4XXTREMEX-A-A25 | G4XXTREMEX-A-A32 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | G4XXTREMEX-A-A5 | G4XXTREMEX-A-A32 | open (OL) | +12 V supply must not touch 5 V sensor reference |
If any reading doesn't match, stop and get help before powering up.

| Severity | Code | Subject | Message |
|---|---|---|---|
| warn | DBW_MOTOR_CURRENT | G4XXTREMEX-B-B18 | Cannot confirm G4X XtremeX can drive the throttle motor: G4XXTREMEX-B-B18 "Aux 9" has no peak rating (motor stalls at ~14 A). |
| warn | DBW_MOTOR_CURRENT | G4XXTREMEX-B-B26 | Cannot confirm G4X XtremeX can drive the throttle motor: G4XXTREMEX-B-B26 "Aux 10" has no peak rating (motor stalls at ~14 A). |
| 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 | DBW_SHARED_5V | G4XXTREMEX-A-A32 + OEM-A-20 + OEM-A-21 + OEM-E-5 + SP-5V1-1 + TB-J-VCC | These 5 V supplies are separate in the stock car (OEM-A-20 [s2k_vcc2], OEM-A-21 [s2k_vcc1], OEM-E-5 [s2k_vcc3]) and here share one ECU 5 V (G4XXTREMEX-A-A32). On a drive-by-wire car the OEM splits them so one short or fault can't corrupt both throttle/pedal tracks at once. G4X XtremeX has 1 5 V sensor supply pin(s). All are in use, so decide: accept the shared supply (and rely on the ECU's DBW fault checks), or add a separate regulated 5 V for the sub tracks. |
| warn | LOAD_UNKNOWN | G4XXTREMEX-A-A1 | G4XXTREMEX-A-A1 "Injector 4" drives OEM-B-2 Injector 4 (load 1.2 A) but its current rating is unknown. Check the ECU manual. |
| warn | LOAD_UNKNOWN | G4XXTREMEX-A-A18 | G4XXTREMEX-A-A18 "Aux 4" drives OEM-E-12 Radiator fan control (load 0.2 A) but its current rating is unknown. Check the ECU manual. |

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 | SUPPLY_GROUP | G4XXTREMEX-A-A32 + OEM-A-20 + OEM-A-21 + OEM-E-5 + SP-5V1-1 + TB-J-VCC | Supplies meant to stay independent share one net: OEM-A-20 [s2k_vcc2], OEM-A-21 [s2k_vcc1], OEM-E-5 [s2k_vcc3]. The new ECU has no free 5 V reference, so they share one: normal on a standalone, but a short on any of these sensors drops them all. |

Notes
Fit check: unconfirmed. Confirm these before building: - Throttle motor draws ≥ ~14 A at stall; this ECU's H-bridge rating is not known - Trigger pattern needs a workaround: F22C1 shares the F20C trigger pattern (12-tooth crank + cam); Link documents the S2000X (AP1) but the AP2 is not separately named. Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Not wired: - OEM-E 9: Ignition signal: key-on 12 V sense — optional in a swap (the main relay is energized from keyed 12 V, not from this pin); Link G4X XtremeX has no dedicated key-on input - OEM-E 19: Evap canister vent shut valve: no free low_side/relay_control/heater_low_side/ls_hs/injector on Link G4X XtremeX - OEM-E 25: Engine speed pulse (tacho): no free tacho/frequency_out/low_side/ls_hs on Link G4X XtremeX - OEM-E 26: Vehicle speed output: no free frequency_out/tacho/low_side/ls_hs on Link G4X XtremeX - OEM-E 13: Multiplex communication: no free k_line on Link G4X XtremeX - OEM-A 28: A/F sensor signal −: not classified in the library; wire by hand - OEM-A 31: A/F sensor signal +: not classified in the library; wire by hand - OEM-B 10: Alternator L signal: not classified in the library; wire by hand - OEM-B 19: Throttle actuator command to throttle control module (SEFD): not classified in the library; wire by hand - OEM-B 20: Throttle actuator command to throttle control module (SEDF): not classified in the library; wire by hand - OEM-E 27: Immobilizer code: not classified in the library; wire by hand - OEM-E 29: Service check signal: not classified in the library; wire by hand - OEM-E 30: Write enable signal: not classified in the library; wire by hand
