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 | 1: read the Findings page before cutting any wire |
| Size of the job | 99 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. |
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-1 | KV12-C-17 | open (OL) | +12 V supply must not touch sensor ground | |
| 3 | KV12-A-19 | KV12-D-21 | open (OL) | power ground must not touch 5 V sensor reference | |
| 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 |
If any reading doesn't match, stop and get help before powering up.

| Severity | Code | Subject | Message |
|---|---|---|---|
| error | DBW_SENSOR_INPUT | tps | Only 1 throttle-position track(s) found. An electronic throttle needs two (main and sub) so the ECU can cross-check them. |
| 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-A36-1 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-A36-2 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-A34-32 ↔ KV12-B-20 | OEM-A34-32 "High-pressure fuel pump spill valve (FPD)" [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-A35-1 ↔ KV12-B-21 | OEM-A35-1 "Canister vent valve (VPMP)" [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-A35-19 ↔ KV12-B-22 | OEM-A35-19 "Fuel pump control (FPC)" [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-A35-8 ↔ KV12-B-23 | OEM-A35-8 "Leak detection pump (MPMP)" [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-A36-11 ↔ KV12-B-24 | OEM-A36-11 "Purge valve (PRG)" [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. |
| info | NET_FAMILY | OEM-A33-12 ↔ KV12-C-10 | OEM-A33-12 "Intake air temperature (THA, in MAF)" [temp_in] is wired to KV12-C-10 "Analog Input Channel 9" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | OEM-A34-13 ↔ KV12-A-4 | OEM-A34-13 "High-pressure fuel pump spill valve (FPF)" [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-A36-16 ↔ KV12-A-2 | OEM-A36-16 "OCV intake bank 2 (OC2)" [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-A36-29 ↔ KV12-D-7 | OEM-A36-29 "Sensor ground (E1)" [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-A36-30 ↔ KV12-C-9 | OEM-A36-30 "Engine coolant temperature (THW)" [temp_in] is wired to KV12-C-9 "Analog Input Channel 8" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
