Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 103 wires · 10 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-D-1 | KV12-A-19 | open (OL) | +12 V supply must not touch power ground | |
| 2 | KV12-D-21 | KV12-A-19 | open (OL) | 5 V sensor reference must not touch power ground | |
| 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-1 | KV12-D-21 | open (OL) | +12 V supply must not touch 5 V sensor reference |

| 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, but the motor current at OEM-X2-6 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, but the motor current at OEM-X2-5 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. |
| warn | NET_FAMILY | OEM-X1-61 ↔ KV12-B-20 | OEM-X1-61 "EVAP canister vent solenoid" [low_side_out] is wired to KV12-B-20 "Auxiliary Output 11" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-X1-68 ↔ KV12-B-21 | OEM-X1-68 "Malfunction indicator lamp (MIL)" [low_side_out] is wired to KV12-B-21 "Auxiliary Output 12" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-X2-16 ↔ KV12-B-22 | OEM-X2-16 "Camshaft actuator solenoid (VVT)" [low_side_out] is wired to KV12-B-22 "Auxiliary Output 13" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-X2-32 ↔ KV12-B-23 | OEM-X2-32 "Generator field duty control" [low_side_out] is wired to KV12-B-23 "Auxiliary Output 14" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-X2-61 ↔ KV12-B-24 | OEM-X2-61 "Charge indicator signal" [low_side_out] is wired to KV12-B-24 "Auxiliary Output 15" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| warn | NET_FAMILY | OEM-X2-8 ↔ KV12-B-25 | OEM-X2-8 "EVAP canister purge solenoid" [low_side_out] is wired to KV12-B-25 "Auxiliary Output 16" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
| info | NET_FAMILY | KV12-C-25 ↔ KV12-D-5 | KV12-C-25 "Analog Sensor 0V Reference" [sensor_ground] is wired to KV12-D-5 "Crank Index Sensor -" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | OEM-X1-37 ↔ KV12-C-13 | OEM-X1-37 "Intake air temperature (IAT) signal" [temp_in] is wired to KV12-C-13 "Analog Input Channel 12" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-X2-10 ↔ KV12-A-1 | OEM-X2-10 "Cylinder shutoff solenoid 1 (AFM)" [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-X2-11 ↔ KV12-A-4 | OEM-X2-11 "Cylinder shutoff solenoid 4 (AFM)" [low_side_out] is wired to KV12-A-4 "Injection Channel 12" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | OEM-X2-14 ↔ KV12-A-2 | OEM-X2-14 "Cylinder shutoff solenoid 2 (AFM)" [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. |
| info | NET_FAMILY | OEM-X2-21 ↔ KV12-C-12 | OEM-X2-21 "Engine coolant temperature (ECT) signal" [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. |

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (GM E38 (C6 Corvette)); not documented for this ECU 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-X1 20: Battery positive voltage (batt hot): Emtron KV12 has no battery-constant input; not needed - 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-X2 29: Knock sensor 2 signal A: no free knock input on Emtron KV12 - OEM-X2 30: Knock sensor 2 signal B: no free knock input on Emtron KV12 - OEM-X1 48: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on Emtron KV12 - OEM-X1 57: VSS output to ABS (128k): no free frequency_out/tacho/low_side/ls_hs on Emtron KV12 - KV12-D 15: Ignition Switch Input: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
