http://www.painlessperformance.com/Manuals/30103Instruction.pdf well this is the fan controller i plan on using so i will probably swap the fusible link for the circuit breaker since its supplied with the kit. it still needs some type of circuit protection because its wired directly to the battery through the wire to the starter then to the battery.
the idea of fusible links is good, but im just going to need to keep extras just in case there is a problem(knock on wood there wont be any) but i guess if i wire it right, there wont be any.
