ZOZOMOTORS Electric Fan Relay Wiring Kit
Specifications:
- Voltage: 12VDC
- Temperature: 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 included
- How to use: Connect the color-coded wires per the diagram (product image 2)
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 harness
- Connect the GREY (86 pin) and COFFEE (87 pin) wires from the A/C relay to the ground
- Connect the BLACK wire (85 pin) from the A/C relay to the +12 volt of the A/C compressor clutch wire

I put about 2k miles on it so far, thermal switch is very accurate at 175°, still working great. Relay is holding up fine with 2 fans on it.I had a spare circuit so I didn't use the fuse holder or the crimp connectors.
product Great

Wired it all in according to the instructions and doesn’t work. Triple checked it was wired correctly and still did not turn in fans. Probably defective relays. Got power to then but not to the fans

Used this to wire up a trans cooler fan and it works great so far. Easy install with the directions provided and good value.

Happy with purchase. Installed it on a Datsun 620 with electric fan. Follow instructions and it’ll work how it’s supposed to work.
