Chevrolet Camaro SS 2010-15 (LS3/L99) — MoTeC — M150

Drawn by Michael Gnankou · Rev 0 · proposal · 2026-10-08

Before you start

Status	proposal · not yet verified: nobody has reported building and running this harness
Open errors	none
Size of the job	105 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	M150-A-10	M150-A-24	open (OL)	5 V sensor reference must not touch power ground
2	M150-B-13	M150-A-24	open (OL)	+12 V supply must not touch power ground
3	M150-D-12	M150-A-24	open (OL)	+12 V supply must not touch power ground
4	M150-A-26	M150-A-10	open (OL)	sensor ground must not touch 5 V sensor reference
5	M150-A-26	M150-B-13	open (OL)	sensor ground must not touch +12 V supply
6	M150-A-26	M150-D-12	open (OL)	sensor ground must not touch +12 V supply
7	M150-B-13	M150-A-10	open (OL)	+12 V supply must not touch 5 V sensor reference
8	M150-D-12	M150-A-10	open (OL)	+12 V supply must not touch 5 V sensor reference
