Setting up a switch for electric fan with a relay on a Jeep Grand Cherokee WJ 

Shown here on a 2002 Jeep Grand Cherokee I get to the basics in this step by step for installing a manual switch for your electric fan. This install will include a relay, fuse, toggle switch and the size wire needed for this install. If your jeep is like mine the standard fan relay is unreliable so might as well control the switch yourself.
