C&R Racing has developed a line of wiring harnesses and installation kits to simplify fan wiring installation and add to your fan’s long-term durability and performance. Wiring harness installation kits are available for vehicles with and without air conditioning to suit your specific needs. Select either a single or dual fan relay harness with or without an additional A/C harness. Next, choose a sending unit that fits your specific applications performance operating temperature. Finally choose a double or triple relay aluminum mounting box to safely and securely house relay and wire leads from the elements.

Additionally, wiring harnesses and mounting boxes are sold in kits to further simplify the ordering process. However, temperature sending units are sold separately from the kits to allow for custom application specific temperature levels to suit your specific needs.
