How do you find the fusible link in a 1984 Chevrolet Caprice V8?

I have a 85 caprice classic its under hood on fire wall it is not marked so you will have to trace your wires there isn't to many because of age

its on the fire wall under the hood its about 1.5 inches long and round it isn't marked so youwill have to trace the fuseable llinks it should be easy since the car is older not alot of wires
