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 | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 71 wires · 12 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 | KV12-A-19 | KV12-D-1 | open (OL) | power ground must not touch +12 V supply | |
| 2 | KV12-A-19 | KV12-D-21 | open (OL) | power ground must not touch 5 V sensor reference | |
| 3 | KV12-C-17 | KV12-D-1 | open (OL) | sensor ground must not touch +12 V supply | |
| 4 | KV12-C-17 | KV12-D-21 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 5 | KV12-D-21 | KV12-D-1 | open (OL) | 5 V sensor reference must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

| Severity | Code | Subject | Message |
|---|---|---|---|
| warn | DATASET_GAP | KV12 A | 5 of 26 cavities on KV12 A have no pin data (5,6,7,12,13). Anything there is invisible to these checks. |
| warn | DBW_MOTOR_CURRENT | KV12-B-18 | Cannot confirm KV12 can drive the throttle motor: KV12-B-18 "Auxiliary Output 9" is rated 5 A peak, but the motor stall current at OEM-E14-8 is unknown. Add the motor's peak current from a source, or measure the motor resistance: peak ≈ 14 V ÷ R (Hondata measured 4.9 A for a Civic Si body, 10.4 A for a ZDX body; holding current is about 1 A). |
| warn | DBW_MOTOR_CURRENT | KV12-B-19 | Cannot confirm KV12 can drive the throttle motor: KV12-B-19 "Auxiliary Output 10" is rated 5 A peak, but the motor stall current at OEM-E14-7 is unknown. Add the motor's peak current from a source, or measure the motor resistance: peak ≈ 14 V ÷ R (Hondata measured 4.9 A for a Civic Si body, 10.4 A for a ZDX body; holding current is about 1 A). |
| warn | DBW_MOTOR_ISOLATION | KV12-D-20 | KV12-D-20 "Auxiliary Output 9-12 14V Supply" is fed from the same net as the ECU main supply (KV12-D-1). 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 KV12 cuts the H-bridge internally. |
| info | NET_FAMILY | OEM-E13-14 ↔ KV12-C-7 | OEM-E13-14 "Engine coolant temp (THW)" [temp_in] is wired to KV12-C-7 "Analog Input Channel 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-E13-19 ↔ KV12-D-7 | OEM-E13-19 "MAF ground (EVG)" [sensor_ground] is wired to KV12-D-7 "Sync Sensor -" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | OEM-E13-22 ↔ KV12-C-12 | OEM-E13-22 "Intake air temp (THA)" [temp_in] is wired to KV12-C-12 "Analog Input Channel 11" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-E14-19 ↔ KV12-A-1 | OEM-E14-19 "VVT oil-control valve LH (OCV−)" [low_side_out] is wired to KV12-A-1 "Injection Channel 9" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-E14-29 ↔ KV12-A-2 | OEM-E14-29 "ACIS induction VSV" [low_side_out] is wired to KV12-A-2 "Injection Channel 10" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |

Notes
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-E15 1: Battery constant (+12V): Emtron KV12 has no battery-constant input; not needed - OEM-E13 16: VVT position sensor LH (VVL+): no free cam_hall/cam_vr/frequency_in input on Emtron KV12 - OEM-E13 24: VVT position sensor LH (VVL−): no free cam_hall/cam_vr/frequency_in input on Emtron KV12 - OEM-E13 15: VVT position sensor RH (VVR+): no free cam_hall/cam_vr/frequency_in input on Emtron KV12 - OEM-E13 23: VVT position sensor RH (VVR−): no free cam_hall/cam_vr/frequency_in input on Emtron KV12 - KV12-D 12: Knock 1 - left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - KV12-D 18: Knock 2 - left open: the stock knock sensor has one ECU wire; check the ECU manual for single-wire knock sensors - OEM-E15 11: OBD-II / DLC3 data (SIL): no free k_line on Emtron KV12 - OEM-E11 5: Diagnostic test (TC): no free k_line on Emtron KV12
