From the little I know about automotive wiring, the rule of thumb in a circuit is to use a fuse that is rated for 10% to 15% above the expected amperage. Another factor to consider is the amperage output of the alternator. As all know, the Compufire puts out quite a bit more amperage than a stock unit. Finally, 12 gauge wire is good for about 41 amps of current while 5 gauge wire is good for about 118 amps of current. I hope this helps when diagnosing and designing wiring harnesses.
