b'Wiring:Yellow: (10 awg.) Connect Yellow wire to fuse holder, with supplied yellow butt connector, route to battery. Fuse holder needs to be within 18 from power source. Black: (12 awg.) Connect to ground Temp Sensor Connecting Wires: Connect Grey from fan switch to red of thesensor. Purple from Module to Black of the sensor. We reccomend soldering these connections and covering with Heat Shrink Supplied (see Fig. 1) **Yellow: (second fan output) : (18 awg.) 500 mA output for secondary fan operation. Blue: (18 awg.) Connect to 12V A/C compressor trigger, this will turn the fan(s) on at 100% when A/C is running(+12 Volt activation) or if not connected to A/C, can be connected to toggle switch for manual overide. (CANNOT BE USED IN COMBINATION) Orange (18 awg.) Connect to switch output (IGN or ACC) (+12 volts) 2 Pin Connector: Connect mating plugs together from Module to fan. *IF SECOND FAN OUTPUT (SMALL YELLOW) AND/OR AC INPUT (BLUE) ARE NOT IN USE, USE PROVIDED HEAT SHRINK TO TERMINATE WIRES** SECOND FAN REQUIRES THE USE OF A 40 AMP RELAY, NOT INCLUDED. Second fan will engage only when first fan reaches 100%. Second fan will come on at 100% powered through the relay. Connect 18 AWG yellow (small yellow signal wire-Second fan output 500mA) to the 40 Amp Relay coil (-) , connect other relay coil terminal to (+Power). Note: Unit Signal uses a (-) negative. Connect 12 Volt power from Battery through the relay to the Fan.When Fan 1 reaches 100% the unit sends (-) ground signal to Yellow Wire Output energizing the relay.Compressor 12V input/ 35Amp Fuseoveride switch.
