The fuse-able link ( a small Gage wire) is probably the best for use in this
application:

1 will take almost a dead short to burn it out
2 will take an extreme over load for a long time before burning out (slow
blow)
3 does not suffer from vibration failures
4 if it burns out, you have a serious short in your electrical system (not
just a grounding problem)
5 if it burns out, it WILL NOT create problems behind the dash or with
components. That is caused by a failure of the alternator that allows the
failed alternator to supply 100 volts to the wiring. (the APC will protect
your wiring from this over voltage.)
6 If you have lost a fuse-able link, you should go looking for:
a a short in your electrical system
b a bad alternator supplying 100 volts ( also blows up batteries)
7 if the fuse-able link burns out - fix the problem with an easy
replacement.

A fuse is a bad component for this application because it will blow out
with an overload of less than a second, and leave your dark and stranded.
Only a circuit breaker (self resetting) in this application will even come
close to working as well as the fuse-able link.

Every GMCer I know of, that put a fuse in this application has gone back to
using the fuse-able link.
