These FAN-THOM II electric fan relay kits come with a threaded thermostat that screws into the engine block or intake manifold for a clean and professional look. These kits provide protection for your electric fans and wire harnesses. They supply constant voltage, protect against voltage and amperage spikes, and prevent the fan from back-feeding voltage through your vehicle's wire harnesses.
These kits include:
* SPST 40 amp relay
* 30 amp circuit breaker
* Thermostatic switch
* Relay base with harness
* Crimp-on terminals
* Mounting hardware
