$147.95

This kit is for vehicles with Electronic Fuel Injection (EFI) with positive (+) fan triggering.  This completely waterproof kit installs easily and plugs directly into your electric fan via a standard fan plug – of which most of the major fan manufacturers use.  Harnesses dressed in Split Braided Tubing for that show car look!

Triggering is fully automatic (see specifications below for specifics).  Powers fans requiring up to 35A continuously with minimal voltage drop!

Includes full color step-by-step instructions and all hardware shown.
