Hello! First post here. I need to replace the entire electrical system in a 90 Silverado. Can a wire plan be purchased?

Are you looking for an entire wiring harness?
Or are you are just looking for the wiring diagrams....they are a sticky in the engine and performance section.

Like he said, at top is search bar use " service manuals " you'll get the link for all the PDF OE service manuals.
