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 | 2: read the Findings page before cutting any wire |
| Size of the job | 41 wires · 12 connectors · 5 part lines |
| Tools | Crimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink |
| 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 | FT450-A-A13 | FT450-A-A12 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | FT450-A-A13 | FT450-A-A7 | open (OL) | +12 V supply must not touch power ground | |
| 3 | FT450-A-A12 | FT450-A-A14 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 4 | FT450-A-A12 | RLY1-R-OUT | open (OL) | sensor ground must not touch +12 V supply | |
| 5 | FT450-A-A13 | FT450-A-A14 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 6 | FT450-A-A14 | RLY1-R-OUT | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 7 | FT450-A-A7 | FT450-A-A14 | open (OL) | power ground must not touch 5 V sensor reference | |
| 8 | FT450-A-A7 | RLY1-R-OUT | open (OL) | power ground must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

Notes
Fit check: unconfirmed. Confirm these before building: - Trigger pattern for Honda F22C1 not found in the ECU's docs (Confirmed absent from documented trigger/decoder list. Trigger F22C1 is not in the FuelTech docs (open), but the 2006-09 AP2 has drive-by-wire and FT450 has no DBW output (spec table p.8 'DBW: NO', 0 Yellow outputs) -> not_suitable for F...) - No knock input; the stock knock sensor would be unused
