Haynes & Chilton are extremely basic manuals and very generalized. Some repair information is missing, and some is incorrect, same with the specifications they list. Nice to read while you're in the bathroom
but don't rely on it if you want to repair a vehicle. If you want accurate information, subscribe to Alldata, or better yet, get the factory shop manual.
What information are you looking for as far as the underhood fuse panel? (Not all years/models have them)
