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 | 66 wires · 13 connectors · 5 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. |

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 | KV8-D-1 | KV8-B-34 | open (OL) | +12 V supply must not touch power ground | |
| 2 | KV8-D-1 | KV8-C-17 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | KV8-B-34 | KV8-D-21 | open (OL) | power ground must not touch 5 V sensor reference | |
| 4 | KV8-C-17 | KV8-D-21 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 5 | KV8-D-1 | KV8-D-21 | 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 |
|---|---|---|---|
| error | REQUIRED_UNMAPPED | OEM-E7-7 | Required OEM function "ETCS throttle motor - (M-)" (hbridge_out) is not connected to the new ECU. |
| error | REQUIRED_UNMAPPED | OEM-E7-8 | Required OEM function "ETCS throttle motor + (M+)" (hbridge_out) is not connected to the new ECU. |
| warn | DATASET_GAP | KV8 A | 14 of 26 cavities on KV8 A have no pin data (1,2,3,4,5,6,7,8,9,12,13,14,15,19). Anything there is invisible to these checks. |
| info | NET_FAMILY | KV8-C-17 ↔ KV8-D-5 | KV8-C-17 "Analog sensor 0V reference" [sensor_ground] is wired to KV8-D-5 "Crank index sensor −" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | OEM-E3-5 ↔ KV8-B-7 | OEM-E3-5 "Fuel pump control (FC)" [low_side_out] is wired to KV8-B-7 "Injection 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-E3-6 ↔ KV8-B-8 | OEM-E3-6 "Check-engine lamp (W)" [low_side_out] is wired to KV8-B-8 "Injection 8" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-E6-14 ↔ KV8-C-6 | OEM-E6-14 "Coolant temperature (THW)" [temp_in] is wired to KV8-C-6 "Analog in 5" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-E6-22 ↔ KV8-C-12 | OEM-E6-22 "Intake air temperature (THA)" [temp_in] is wired to KV8-C-12 "Analog in 11" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | UNMAPPED | OEM | 4 optional OEM pins are not mapped: OEM-E3-11 Serial diagnostic (SIL); OEM-E5-12 Canister close valve (CCV); OEM-E6-7 EVAP purge VSV (PRG); OEM-E7-5 ACIS intake VSV |

Notes
Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Open items: - OEM-E7 7: ETCS throttle motor - (M-): no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand - OEM-E7 8: ETCS throttle motor + (M+): no +/− pair in the pinout (multi-phase or half-documented motor); wire by hand Not wired: - OEM-E3 1: Battery constant (BATT): Emtron KV8 has no battery-constant input; not needed - KV8-D 12: Knock 1 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - KV8-D 18: Knock 2 − left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - OEM-E5 12: Canister close valve (CCV): no free low_side/relay_control/heater_low_side/ls_hs/injector on Emtron KV8 - OEM-E6 7: EVAP purge VSV (PRG): no free low_side/relay_control/heater_low_side/ls_hs/injector on Emtron KV8 - OEM-E7 5: ACIS intake VSV: no free low_side/relay_control/heater_low_side/ls_hs/injector on Emtron KV8 - OEM-E3 11: Serial diagnostic (SIL): no free k_line on Emtron KV8
