The coolant temperature switch and fan control switch are located sie by side, mounted in the steel portion of the heater hose that runs from the thermostat housing to the firewall, it is underneath the air intake tube and the ignition coil pack, mounted to the back of the cylinder head. Either drain out some coolant or be very quick, and you can unplug and unscrew each switch from the hose and replace it with a new one. Make sure the engine is cold. After replacing make sure to check the coolant level add as neccessary. The single wire connector switch is for the guage, and the other is for fan control. Hope this helps, let me know.
