SPAL Fan Harness With Relay

Note: This kit includes a Spal brand sealed relay similar to Hella's 4RD 007.794-301 sealed 5 blade relays.

This kit does NOT include a thermoswitch. It is meant to be used with 185FH or 195FH in a dual fan setup.

The thermostat switch acts as a ground for a relay. As the thermostat reaches the appropriate temperature it completes the ground circuit for the fan relay, then activates your radiator or oil cooler fans.
