Absolutely — the 2009 Nissan Altima Service & Repair Manual includes the full OEM wiring schematics for the ignition system, including the connections from each ignition coil to the ECM, individual pin assignments, and power/ground routing.
It provides clear diagrams showing all four ignition coils (with integrated power transistors), their wire colors, circuit paths, and ECM terminal locations. So if you're tracing ignition signal wires, diagnosing misfires, or verifying pinouts on coil connectors, everything you need is in there — right down to the joint connectors and labeled ECM pins.
