About this item

  • [Easy Installation] This dual fan wiring harness kit includes a straightforward wiring diagram, making it simple to wire your dual electric fans. Connect the RED wire to the 12VDC positive battery terminal, the COFFEE wire to the fan positive terminal, the BLACK wire to the ignition, and the GREY wire to the sending unit. This kit is a direct replacement part compatible with 10, 12, 14, and 16-inch cooling fans.
  • [Temperature Control] The temperature switch activates the fan at approximately 185 degrees Fahrenheit and deactivates it at 175 degrees Fahrenheit. The included temperature sensor features a 3/8-inch pipe thread, and a 1/2-inch adapter is provided for added versatility.
  • [Complete Kit] This electric cooling fan thermostat kit comes with everything you need for installation: a 40A relay, wiring harness, thermostat switch, 3/8 inch to 1/2 inch adapter, inline fuse holder, two 20 amp fuses, one spade connector for the temperature sensor, eight ring terminals, and four wire connectors. This comprehensive kit ensures you have all the necessary components for a seamless setup.
  • [OE Style Thermostat] The included thermostat is designed in OE style for mounting in the cylinder head of the engine or any water jacket if needed. For proper operation, the thermostat must be grounded through its threads to the engine, and the engine itself must be grounded.
  • [High-Profile Fan Compatibility] If you plan to use high-profile fans, you may need to crimp or solder larger wires to accommodate higher current draw. The included 14AWG wires are rated for 15 amps and may not be sufficient for fans with a higher amperage requirement.

This is a great setup for retro fitting e fans on your vehicle. The only issue I had with it was one fuse holder, the spade was a little loose, I just used a scribe to push the spade tighter. The other is the sending unit is rated to come on at 185°, mine doesn't activate until 193°. Both issues are not a big deal, just know to expect a little variable on activation temp, once the fans kick on it pulls the temp down quickly. A great product for e fan installation and easy to wire up with good instructions included. Well worth the money!

A good value, but the product wiring diagram was a bit confusing for me. See my attached wiring diagram that helped me clarify. The fans and temperature switch each need their individual grounds, but are not grounded directly to each other like the ZDZD Motors diagram confusingly indicates to me. Remember, like the instructions say, if your radiator is not grounded and/or made from a non metallic substance, you will need to wrap a wire around the temperature switch threads and connect to a ground source, or it will not work. This item saved me a lot of money in the end.
