I have a maxi fuse feeding my AAW panel, another in the starter control circuit and a third for my always hot sub panel for my stereo brain feed and my electric trunk lift. I also have relays for my fan, my head lights and the heat/ac.

Fusible links have some major drawbacks, the worst being a potential fire source. Ford, after many fires, one of which happened on my son's '85 F150, was the last to get away from them as OEM. What can happen is that they can overheat without blowing apart and often cause significant wire bundle damage or potentially even start a fire in a bundle which will then travel to other combustible areas. Another problem with them is that the failed link is often difficult to find especially on a cold, dark and windy night in West Overshoe, SD when a fuse can be found in a few seconds in your panel or in a line and replaced (after the cause of failure is corrected, of course)
