This is a pretty decent price, and manual looks to be in very good condition; at least on the outside.
Besides much bigger drawings than the FSM, it also gives more info regarding electrical specs for systems and components than the FSM. It also gives images of the connector, and the color wire and pin location.
I also saw an EWD for a 1986 priced about the same.
I got mine for $20, but that was from a seller who didn't really know what they had. They just sold books. These manuals are usually listed for about $100.00
