Cold Case Radiators Electric Fan Wiring Kit for EFI Control Applications. If you plan to trigger your electric fans through an aftermarket ECU, this is the kit for you.

Most EFI kits have provisions to control electric fans from within the program. Our kit bridges the ECU to the fans, so you do not have to run a thermostat switch. This simple wiring kit includes high-quality wire, a relay, an inline fuse, and fan pigtails.
