Which S15 years does this manual cover?
Every year from 1982 to 1990 — 9 separate manuals, one per model year. Pick your year in the selector; the manual you receive is matched to that exact year, engine and trim.
Is this the OEM GMC S15 manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams GMC published for the S15, organized by system — not a condensed aftermarket summary.

Yes. Full wiring diagrams are part of every S15 manual, alongside repair procedures, specifications and diagnostic information.

16 recalls are on federal record across the 1982–1990 S15, 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 GMC dealers.
Why do some S15 years cost more?
Every S15 year is $29.99.
