Due to the ludicrous delay in shipping of my Delta Current Controls (http://www.dccontrol.com/index.htm ) fan controller that was ordered over three weeks ago and the fact that my Flex A Lite VSC controller (http://www.explorerforum.com/forums/showthread.php?t=161482&highlight=vsc ) finally crapped out, I needed a fan controller immediately, therefore, I picked up a JEGS Cooling Fan Harness and Relay Kit (https://www.jegs.com/webapp/wcs/sto...lgy/l fYckk6ErXA3ax8ReHA==&ddkey=OrderItemAdd ).

This kit is touted by Jegs as “This Heavy Duty 12-18 gauge wiring kit provides a continuous supply of voltage, preventing drop off common with OE wire thus protecting the unit from damage. It can be utilized with an on/off switch or used solely as a temperature controlled switch. Includes 40/30 amp relay, circuit breaker, 48'' of wire, assorted terminals and connectors. Available in two temperature ranges to complement your engine thermostat.”

I ordered the kit for a 195 F thermostat. As is customary when dealing with Jegs, the package arrived as promised. Jegs is a first class company to do business with.

The installation of this kit is rather simple. Since this is only a short-term installation, I elected to use only the temperature controlled switch; no manual control.

Since this kit will be replaced as soon as the Delta Current Controls controller arrives, I did not dress the wiring.

The first step in the install was to disconnect the battery negative terminal. This was followed by attaching the 12 g red wire from the relay to the positive lead on the fan. The negative lead on the fan was then attached to ground. The gray wire from the relay was then connected to an ignition switcher 12 v positive wire. The remaining red wire was connected to a circuit breaker and then to the positive battery terminal. Since I am not using the thermal switch, the yellow wire from the relay was grounded. Then the battery was reconnected.

The installation took all of 5 minutes.

A brief road test in town and a 10 mile run on I75 proved the fan controller works as advertised.

This is a straightforward kit that cleanly does the job. I recommend this to anyone who wants a simple, inexpensive controller or to have as a backup if the more expensive controller fails.
