Yep, this manual does include full ECM pinout diagrams — including the power and ground circuits you’re after.
You’ll find:
- ECM positive battery feeds (like constant 12V supply)
- Ground locations and pin numbers
- Connector views with pin numbers, wire colors, and function labels
- Related fuse and relay locations in the power distribution section
If you’re tracking down a no-start, sensor issue, or voltage drop, this manual’s got the info to walk you through it without no guessing. Just pull up the "ECM Wiring Diagram" and "Power Supply/Ground Circuit" sections inside the EC or PG (Engine Control / Power/Ground) chapters.
