Thank you for purchasing your MN12 Performance Intercooler Fan Kit designed for the 1989-1993 Thunderbird/Cougar SC. The kit comes with all the needed hardware and instructions to install the fan kit with no special tools required. This fan kit is designed to turn the fan on when the ignition is turned ON. Intercooler temps can be reduced by as much as 30 degrees F. Installation time is about 1-2 hours.
Installation Instructions
Disconnect the battery and remove it from the car. Remove the black rubber stone guard from the underside of the front cross member. Remove the radiator support bolts, drain the radiator and remove the upper radiator hose so the radiator fan may be removed from the car. Disconnect the transmission lines (automatics only) from the radiator and tie them up (while removing the radiator is not mandatory it makes for an easier installation). With radiator and battery removed position the fan on the backside of the intercooler about 3 inches from the top with the fan wiring located at the top. Insert the rubber washers over the nails and insert them through the Intercooler with the top nails installed first. Using the supplied Push Pins secure the fan to the Intercooler (see picture)
Using the wiring kit supplied attach the three black wires (ground) to the headlight ground location (see picture).
Next using a 1/8 inch drill bit drill a hole approximately 2.5" inches from the radiator support bolt for mounting the relay. (see picture)
Next locate the ignition wire (R/LG) (red with a light green stripe) in the Fuse box wiring harness. Their are two (R/LG) ignition wires one is a 10 guage wire and the other is a 14 guage wire. Next, disconnect the Power Distribution Box (PDB) from it's support by using a small screw driver to depress the 3 locking tabs that hold it to the metal support. With the PDB disconnected from the bracket trim the wiring harness insulation back about 2 inches to allow enough slack for the tap to be installed on the 14 guage (R/LG) wire. Next unscrew the lower nut that holds the 175amp Megafuse and install the RED 12v power connection.
Install the 3M 901 tap supplied on the ignition wire (R/LG).
Connect the wiring harness to the thermostat switch if not already.
