had to look at the wiring diagram again - that fuse is for dash and tail lites, powered from the ignition sw so that those lites work any time they're turned on [ign on or off] .... things could be wired differently, but .... why? having had lots of these trucks, I've never run across a problem with that fuse, or one burned out
for the dimmer, the 60-66 sw mounts inside, above the floor - if you're into that kind of mod, should work the same as any switch
