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.

Statusproposal · not yet verified: nobody has reported building and running this harness
Open errorsnone
Size of the job67 wires · 9 connectors · 0 part lines
ToolsCrimp and extraction tools for each terminal family (see Connectors) · wire strippers · multimeter · heat gun + heat-shrink
Order of work1. 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 AProbe BExpectWhyReading
1G5VOODOOPROV-A-5G5VOODOOPROV-A-24open (OL)+12 V supply must not touch sensor ground
2G5VOODOOPROV-A-5G5VOODOOPROV-A-25open (OL)+12 V supply must not touch power ground
3G5VOODOOPROV-A-A32G5VOODOOPROV-A-24open (OL)5 V sensor reference must not touch sensor ground
4G5VOODOOPROV-A-25G5VOODOOPROV-A-A32open (OL)power ground must not touch 5 V sensor reference
5G5VOODOOPROV-A-5G5VOODOOPROV-A-A32open (OL)+12 V supply must not touch 5 V sensor reference

If any reading doesn't match, stop and get help before powering up.
