Before you start
| Status | draft · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 69 wires · 12 connectors · 0 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 | MAXXECUGEN2T-MX1-25 | MAXXECUGEN2T-MX1-14 | open (OL) | +12 V supply must not touch sensor ground | |
| 2 | MAXXECUGEN2T-MX1-14 | MAXXECUGEN2T-MX1-12 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 3 | MAXXECUGEN2T-MX1-25 | MAXXECUGEN2T-MX1-12 | open (OL) | +12 V supply must not touch 5 V sensor reference | |
| 4 | MAXXECUGEN2T-MX1-9 | MAXXECUGEN2T-MX1-12 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | MAXXECUGEN2T-MX1-9 | MAXXECUGEN2T-MX1-25 | open (OL) | power ground must not touch +12 V supply |

Notes
Fit check: unconfirmed. Confirm these before building: - Trigger pattern for Honda C30A not found in the ECU's docs (MaxxECU trigger list has no C30A/C32B/NSX (Honda K20/K20A2/K20Z4/F20C only)) 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-D 1: Battery backup (VBU): MaxxECU MaxxECU GEN2 TRACK has no battery-constant input; not needed - OEM-B 13: CRNK 2P — TDC sensor signal: no free crank_vr/frequency_in input on MaxxECU MaxxECU GEN2 TRACK - OEM-B 9: CYL 2P — CYP sensor 2 signal: no free cam_vr/cam_hall/frequency_in input on MaxxECU MaxxECU GEN2 TRACK - OEM-C 4: Tachometer output (NEP): no free tacho/frequency_out/low_side/ls_hs on MaxxECU MaxxECU GEN2 TRACK - OEM-C 10: Traction control: not classified in the library; wire by hand - OEM-C 12: Traction control: not classified in the library; wire by hand - OEM-C 6: Traction control: not classified in the library; wire by hand - OEM-C 8: Traction control: not classified in the library; wire by hand - OEM-D 5: Traction control: not classified in the library; wire by hand - OEM-D 6: Fuel pump voltage monitor (VFP): not classified in the library; wire by hand - MAXXECUGEN2T-MX2 24: 12V supply 3: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
