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 | 64 wires · 9 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. |
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 | 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-D-21 | KV8-C-17 | open (OL) | 5 V sensor reference must not touch sensor ground | |
| 4 | KV8-B-34 | KV8-D-21 | open (OL) | power 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 |

| Severity | Code | Subject | Message |
|---|---|---|---|
| error | REQUIRED_UNMAPPED | OEM-E9-25 | Required OEM function "Camshaft position 2 (G2)" (trigger_in) 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 | OEM-E9-44 ↔ KV8-C-6 | OEM-E9-44 "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-E9-45 ↔ KV8-C-7 | OEM-E9-45 "Intake air temperature (THA)" [temp_in] is wired to KV8-C-7 "Analog in 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-E9-6 ↔ KV8-D-7 | OEM-E9-6 "Cam sensor 1 ground (G1-)" [sensor_ground] is wired to KV8-D-7 "Sync sensor −" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | OEM-E9-73 ↔ KV8-B-7 | OEM-E9-73 "Fuel pressure-up VSV (FPU)" [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-E9-74 ↔ KV8-B-8 | OEM-E9-74 "Purge VSV (EVAP)" [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 | UNMAPPED | OEM | 1 optional OEM pins are not mapped: OEM-E10-16 Tachometer output |

| REQUIRED_UNMAPPED | OEM-E10-33 | Battery-constant (memory) feed of the stock ECU: the new ECU has no such input, so it is not needed. | mapping-proposal |
Notes
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-E9 25: Camshaft position 2 (G2): no free cam_vr/cam_hall/frequency_in input on Emtron KV8 Not wired: - OEM-E10 33: 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-E10 16: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on Emtron KV8
