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 | proposal · not yet verified: nobody has reported building and running this harness |
|---|---|
| Open errors | none |
| Size of the job | 71 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 | MAXXECUPRO-C1-G1 | MAXXECUPRO-C1-M4 | open (OL) | 5 V sensor reference must not touch +12 V supply | |
| 2 | MAXXECUPRO-C1-H1 | MAXXECUPRO-C1-G1 | open (OL) | sensor ground must not touch 5 V sensor reference | |
| 3 | MAXXECUPRO-C1-H1 | MAXXECUPRO-C1-M4 | open (OL) | sensor ground must not touch +12 V supply | |
| 4 | MAXXECUPRO-C1-L4 | MAXXECUPRO-C1-G1 | open (OL) | power ground must not touch 5 V sensor reference | |
| 5 | MAXXECUPRO-C1-L4 | MAXXECUPRO-C1-M4 | open (OL) | power ground must not touch +12 V supply |
If any reading doesn't match, stop and get help before powering up.

Notes
Auto-mapped by auto_map() from the library pin data on 2026-10-11. Review every wire against both manuals before building. Not wired: - OEM-E15 1: Battery constant (+12V): MaxxECU MaxxECU PRO has no battery-constant input; not needed - OEM-E13 16: VVT position sensor LH (VVL+): no free cam_hall/cam_vr/frequency_in input on MaxxECU MaxxECU PRO - OEM-E13 24: VVT position sensor LH (VVL−): no free cam_hall/cam_vr/frequency_in input on MaxxECU MaxxECU PRO - OEM-E13 15: VVT position sensor RH (VVR+): no free cam_hall/cam_vr/frequency_in input on MaxxECU MaxxECU PRO - OEM-E13 23: VVT position sensor RH (VVR−): no free cam_hall/cam_vr/frequency_in input on MaxxECU MaxxECU PRO - OEM-E15 11: OBD-II / DLC3 data (SIL): no free k_line on MaxxECU MaxxECU PRO - OEM-E11 5: Diagnostic test (TC): no free k_line on MaxxECU MaxxECU PRO
