Where is the blower motor resistor on a 1989 Mazda MX-6 and how do you install it?

The blower motor resistor is located under the glove box right behind the blower motor. There is a kick shield under the dash that needs to be removed. The resistor has three harnesses connectors. Unplugged the connectors. Remove the two screws holding it in place. If the resistor is highly corroded or broken, replace.
