Before you start
| 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 | 68 wires · 11 connectors · 1 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 | MAXXECURACE-C1-M4 | MAXXECURACE-C1-H1 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | MAXXECURACE-C1-M4 | MAXXECURACE-C1-L4 | open (OL) | +12 V supply must not touch power ground | |
| 3 | MAXXECURACE-C1-H1 | MAXXECURACE-C1-G1 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 4 | MAXXECURACE-C1-L4 | MAXXECURACE-C1-G1 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | MAXXECURACE-C1-M4 | MAXXECURACE-C1-G1 | open (OL) | +12 V supply must not touch 5 V sensor reference |

| warn | DBW_MOTOR_CURRENT | MAXXECURACE-C2-H2 | Cannot confirm MaxxECU RACE can drive the throttle motor: MAXXECURACE-C2-H2 "MOTOR 1-" is rated 2.0 A, but the motor current at OEM-X60003-42 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). |

Notes
Fit check: unconfirmed. Confirm these before building: - Needs CAN (E46 K-bus/CAN); not documented for this ECU - This car has EWS 3.3 (rolling code) immobilizer; needs a delete/bypass Auto-mapped by auto_map() from the library pin data on 2026-10-06. Review every wire against both manuals before building. Open items: - OEM-X60003 29: Intake camshaft position: no free cam_hall/cam_vr/frequency_in input on MaxxECU MaxxECU RACE Not wired: - OEM-X60001 7: Battery constant (terminal 30): MaxxECU MaxxECU RACE has no battery-constant input; not needed - OEM-X60003 46: Knock sensor 3: no free knock input on MaxxECU MaxxECU RACE - OEM-X60003 47: Knock sensor 4: no free knock input on MaxxECU MaxxECU RACE
