Fan Harness With Relay (40 Amp)

Fitment: This is a 40 amp relay kit. It does not contain a 3/8 NPT thread thermoswitch or on/off switch to turn fans on. Use in conjunction with SPAL 185FH or 195FH when using dual fans, or when using A/C without a trinary switch.

These SPAL electric fan relay wiring kits are designed to automatically turn on your SPAL electric fan when the air conditioning is turned on. They can also be used when dual electric fans are installed using one switching device.
