ZOZOMOTORS Electric Fan Relay Wiring Kit Specifications: Voltage: 12VDCTemperature: Approximately 185'F On - 175'F Off Please note: You need to run a 160 degree thermostat when running this kit with this temp switch. If you got a thermostat above 160 degrees (say 180 thermostat) , your engine will not get cool enough for the fan to shut off Thread Size: the temperature sensor has a 3/8'' pipe thread, and a 1/2'' adapter includedHow to use: Connect the color-coded wires per the diagram (product image 4) The temperature switch supplied with this kit is OE style to mount in the cylinder head of the engine or any water jacket if needed The temperature switch MUST be grounded through the threads to the engine in order for it to work, and the engine MUST be grounded This relay kit is enough to run medium profile or low profile cooling fan. For high profile fan, you can use ZOZOMOTORS heavy duty relay kit P/N 30247. Or crimp/solder bigger wires yourself for pin 30 & 87 to carry enough load for the fan (10 gauge wire - 30 Amps). We recommend to use dual fan relay kit to run dual fan set up If you want to turn on the fan when A/C compressor activates, you would need an additional relay kit and follow the steps below: Connect the RED wire (30 pin) from the A/C relay to the black wire (sending unit) of the original fan relay harnessConnect the GREY (86 pin) and COFFEE (87 pin) wires from the A/C relay to the groundConnect the BLACK wire (85 pin) from the A/C relay to the +12 volt of the A/C compressor clutch wire Package Included: 1x Wiring Diagram 1x 40A Relay with Wiring Harness 1x Temperature Switch 185'F On - 175'F Off 1x 3/8" to 1/2" Adapter 1x Inline Fuse Holder 1x 20 Amp Fuse 1x Spade Connector for The Temp Sensor 4x Ring Terminals 2x Wire Connectors Package Included: 1x Wiring Diagram 1x 40A Relay with Wiring Harness 1x Temperature Switch 185'F On - 175'F Off 1x 3/8" to 1/2" Adapter 1x Inline Fuse Holder 1x 20 Amp Fuse 1x Spade Connector for The Temp Sensor 4x Ring Terminals 2x Wire Connectors 185 On 175 Off Dual Fan Relay Kit ZOZOMOTORS Electric Fuel Pump Relay Kit Fuel Pump Wiring Harness Bypass 40 AM...
