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	99 wires · 10 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
1	MAXXECUGEN2R-MX1-12	MAXXECUGEN2R-MX1-9	open (OL)	5 V sensor reference must not touch power ground
2	MAXXECUGEN2R-MX1-25	MAXXECUGEN2R-MX1-9	open (OL)	+12 V supply must not touch power ground
3	MAXXECUGEN2R-MX1-14	MAXXECUGEN2R-MX1-12	open (OL)	sensor ground must not touch 5 V sensor reference
4	MAXXECUGEN2R-MX1-14	MAXXECUGEN2R-MX1-25	open (OL)	sensor ground must not touch +12 V supply
5	MAXXECUGEN2R-MX1-25	MAXXECUGEN2R-MX1-12	open (OL)	+12 V supply must not touch 5 V sensor reference

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

warn	NET_FAMILY	OEM-X2-33 ↔ MAXXECUGEN2R-MX3-22	OEM-X2-33 "Oil level switch signal" [digital_in] is wired to MAXXECUGEN2R-MX3-22 "AIN 18" [analog_in]. Analog and digital on one net. A switch on an analog input works with a pull-up and a threshold; an analog sensor on a digital input loses its value.
