There are several fuse-links on it. There's a couple down by the starter, one(or two) across the top of the firewall, around the wiper motor, and two or three on the driver side fender, just behind where the inner fender panel drops down, in the area of the alarm key switch.
You may also have an issue with the firewall pass-thru connector, which is what the fuse box bolts up to...those get corrosion a lot, and can create some pretty weird 'lectrical maladies....
The best manual you can have is the factory service manual. You can usually find them on e-bay for around $40 or so, maybe less. Most of the Corvette parts vendors also sell them, but those may be the more generic "shop manual" that covers several year models.
I can e-mail you the wiring diagram...
