Is this the OEM INFINITI M45 manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams INFINITI published for the M45, organized by system — not a condensed aftermarket summary.

Yes. Full wiring diagrams are part of every M45 manual, alongside repair procedures, specifications and diagnostic information.

33 recalls are on federal record across the 2003–2010 M45, listed by year below. The manual carries the manufacturer's diagnostic and repair procedures behind the systems involved; the recall repairs themselves are performed free by INFINITI dealers.
Why do some M45 years cost more?
Every M45 year is $29.99.
