Help on electronics!
I just bought my first 1990 corvette and it is a project car. Need some help for 2 majors things, the gas gauge won't display how much gas i have and the windshield wiper motors wont move. Dunno if this has to do anything with it but the guy before me replaced the CCM, i think thats what they call the silver box behind the radio. But any help on this would be great! I would like to see how much gas i have.

The CCM has nothing to do with the fuel gauge nor the windshield wiper motor. You need to buy the electrical diagnosis manual for your car and it will guide you through diagnosis of both the fuel gauge and the windshield wiper circuit. First check the wiper fuse (25 amps) with an ohmeter.

Here are the Wiper/Washer schematics from the 90 manual.
