Fusible link questions

My car is a 1970 Fury. The FSM calls for a fusible link between the positive terminal on the battery and the starter relay. See picture below. Instead of that, there is a section of garden hose around a terribly degraded piece of wire. I want to put it back to original. Does anyone have a picture that shows where the fusible link should be located and the connectors? How do I know what fusible link to get?

Any guesses on why the garden hose was installed? I'm a little nervous about...
