Before you start

Status	draft · not yet verified: nobody has reported building and running this harness
Open errors	none
Size of the job	94 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

Notes

Fit check: unconfirmed. Confirm these before building: - Needs CAN (GM E38 (C6 Corvette)); not documented for this ECU - Trigger pattern for GM LS not found in the ECU's docs (no GM LS entry in the MaxxECU trigger list) 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-X1 20: Battery positive voltage (batt hot): MaxxECU MaxxECU GEN2 RACE has no battery-constant input; not needed - OEM-X2 29: Knock sensor 2 signal A: no free knock input on MaxxECU MaxxECU GEN2 RACE - OEM-X2 30: Knock sensor 2 signal B: no free knock input on MaxxECU MaxxECU GEN2 RACE - OEM-X2 32: Generator field duty control: no free low_side/ls_hs/injector/hbridge on MaxxECU MaxxECU GEN2 RACE - OEM-X2 61: Charge indicator signal: no free low_side/ls_hs/injector/hbridge on MaxxECU MaxxECU GEN2 RACE - OEM-X2 8: EVAP canister purge solenoid: no free low_side/ls_hs/injector/hbridge on MaxxECU MaxxECU GEN2 RACE - OEM-X1 48: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on MaxxECU MaxxECU GEN2 RACE - OEM-X1 57: VSS output to ABS (128k): no free frequency_out/tacho/low_side/ls_hs 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
