Before you start
| Status | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 61 wires · 10 connectors · 7 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 |

| Severity | Code | Subject | Message |
|---|---|---|---|
| warn | NET_FAMILY | OEM-A-3 ↔ SL8-A-18 | OEM-A-3 "Evap bypass solenoid" [low_side_out] is wired to SL8-A-18 "Auxiliary output 9" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-A-4 ↔ SL8-A-19 | OEM-A-4 "Evap canister vent shut valve" [low_side_out] is wired to SL8-A-19 "Auxiliary output 10" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | SUPPLY_GROUP | OEM-C-19 + OEM-C-28 + SL8-B-2 + SP-5V1-1 | Supplies meant to stay independent share one net: OEM-C-19 [s2k_vcc1], OEM-C-28 [s2k_vcc2]. 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. |
| info | NET_FAMILY | OEM-A-1 ↔ SL8-A-5 | OEM-A-1 "Coolant temp gauge drive" [low_side_out] is wired to SL8-A-5 "Injection channel 5" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-12 ↔ SL8-A-6 | OEM-A-12 "Immobilizer indicator light" [low_side_out] is wired to SL8-A-6 "Injection channel 6" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-16 ↔ SL8-A-14 | OEM-A-16 "Fuel pump relay (JDM)" [low_side_out] is wired to SL8-A-14 "Auxiliary output 5" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-A-17 ↔ SL8-A-15 | OEM-A-17 "A/C clutch relay" [low_side_out] is wired to SL8-A-15 "Auxiliary output 6" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-A-18 ↔ SL8-A-7 | OEM-A-18 "Check engine light (MIL)" [low_side_out] is wired to SL8-A-7 "Injection channel 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-2 ↔ SL8-A-8 | OEM-A-2 "Air control valve solenoid" [low_side_out] is wired to SL8-A-8 "Injection channel 8" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-A-20 ↔ SL8-A-16 | OEM-A-20 "Radiator fan relay" [low_side_out] is wired to SL8-A-16 "Auxiliary output 7" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-A-28 ↔ SL8-A-17 | OEM-A-28 "Air pump relay" [low_side_out] is wired to SL8-A-17 "Auxiliary output 8" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-B-12 ↔ SL8-A-10 | OEM-B-12 "VTEC solenoid" [high_side_out] is wired to SL8-A-10 "Auxiliary output 1" [switch_out]. Configure this output as high side. |
| info | NET_FAMILY | OEM-B-23 ↔ SL8-A-13 | OEM-B-23 "Idle air control valve" [low_side_out] is wired to SL8-A-13 "Auxiliary output 4" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-C-1 ↔ SL8-A-11 | OEM-C-1 "Primary O2 heater" [low_side_out] is wired to SL8-A-11 "Auxiliary output 2" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-C-11 ↔ SL8-A-12 | OEM-C-11 "Secondary O2 heater control" [low_side_out] is wired to SL8-A-12 "Auxiliary output 3" [switch_out]. Configure this output as low side. |
| info | NET_FAMILY | OEM-C-25 ↔ SL8-B-20 | OEM-C-25 "Intake air temp sensor" [temp_in] is wired to SL8-B-20 "Analog input 7 (switchable 1k pull-up)" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-C-26 ↔ SL8-B-19 | OEM-C-26 "Coolant temp sensor" [temp_in] is wired to SL8-B-19 "Analog input 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |

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): Emtron SL8 has no battery-constant input; not needed - OEM-C 29: Cam (TDC2) sensor +: no free cam_vr/cam_hall/frequency_in input on Emtron SL8 - 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 6: Evap canister purge valve: no free low_side/ls_hs/injector/hbridge on Emtron SL8 - OEM-C 2: Alternator control: no free low_side/ls_hs/injector/hbridge on Emtron SL8 - OEM-A 19: Tacho output: no free tacho/frequency_out/low_side/ls_hs on Emtron SL8 - OEM-C 10: VTEC pressure switch: no free switch_in/frequency_in/analog_0_5 on Emtron SL8 - OEM-A 21: K-Line: no free k_line on Emtron SL8 - 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 - SL8-B 4: Ignition switch input: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
