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 | 95 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.

Findings
Open (16)
| 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 | 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. |
| warn | DBW_MOTOR_CURRENT | KV8-B-18 | Cannot confirm KV8 can drive the throttle motor: KV8-B-18 "Aux 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 | KV8-B-19 | Cannot confirm KV8 can drive the throttle motor: KV8-B-19 "Aux 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 | KV8-D-20 | KV8-D-20 "Aux 9–12 14V supply" is fed from the same net as the ECU main supply (KV8-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 KV8 cuts the H-bridge internally. |
| warn | NET_FAMILY | OEM-A34-13 ↔ KV8-B-23 | OEM-A34-13 "High-pressure fuel pump spill valve (FPF)" [low_side_out] is wired to KV8-B-23 "Aux 14" [hbridge_out]. A half-bridge can act as a low-side switch only if configured that way. |
