Painless Performance Fan Relay Wiring Kit 30102 (on@195 off@185)

  • SPST 40 Amp relay
  • 30 Amp circuit breaker
  • Thermostatic switch 195°F On/185°F Off (thread size: ⅜”-18NPT)
  • ½”NPT to ⅜”NPT adapter
  • Relay base with harness (6′ input, 4′ output)

  • Mounting hardware



This Fan-Thom II kit comes with a threaded thermostat that screws into the engine block or intake manifold for a professional looking installation.  This is inexpensive protection for an electric fan and a vehicle’s wire harness.  Provides constant voltage, protects from voltage and amperage spikes and prevents the fan from back feeding voltage through the vehicle’s wire harness.
