The fan which is attached to the 97-04 Ford Mustang Performance Aluminum Radiator Fan Shroud Kit is considered universal and will need to be wired into your vehicle to operate. We have developed a fan wiring guide that will be able to help you convert fan from a 3 wire to a 2 wire connection. The url has been provided below. You can either click on this link, or copy and paste the url into your web browser.
In short, your Mustang has a dual speed fan with two positive wires and one negative. The positive wires will be twisted together and attached to the positive (blue) Mishimoto wire. The remaining negative wire from the harness will connect to the negative (black) Mishimoto wire.
Many customers elect to cut the plug off the factory fan they are removing from the vehicle, rather than cutting into the body harness. This will allow you to plug in the fan just as if it were stock.
