Mandatory Connections
1. Connect the positive “+” terminal to a low amp 12 volt positive (+) source. (i.e. fuse box) using
thin red wire and fuse taps (if necessary) provided in the kit.
Note: Attach this wire to an ignition controlled source to stop the fan unit from operating when
the vehicle is shut off.
2. Connect the “B” terminal to a high amp 12 volt positive (+) power source. (i.e. battery, starter
solenoid) using the thick red wire and in line fuse holder provided in the kit (do not install the
fuse at this time).
3 Connect the “G” terminal to ground. (i.e. chassis, negative(-) side of battery) using the thick
black wire provided in the kit.
5. If you have air conditioning: with 3-way connector provided, pass the A/C clutch positive(+)
wire (connected to the A/C compressor) through the connector. Place the green wire provided
into the closed end of the connector. Crimp metal plate. Snap plastic cover into place. Attach
green wire to the "C" terminal of the control box.
