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

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 5: Intake camshaft position: no free cam_hall/cam_vr/frequency_in input on MaxxECU MaxxECU GEN2 RACE Not wired: - OEM-X60001 7: Battery constant (terminal 30): MaxxECU MaxxECU GEN2 RACE has no battery-constant input; not needed - OEM-X60003 31: Knock sensor, cylinders 4-6 (A): no free knock input on MaxxECU MaxxECU GEN2 RACE - OEM-X60003 32: Knock sensor, cylinders 4-6 (B): no free knock input on MaxxECU MaxxECU GEN2 RACE - MAXXECUGEN2R-MX2 24: 12V supply 3: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
