I got Perma Cools adjustable electric fan wiring kit. I also ordered the relay for dual fans.

I just don't get the instructions. There is a module , it has a connector and the temp sensor probe. The harness that connects into the module has red, yellow, brown, blue, and black wires.

Red is power
Black is ground
Yellow is for fan #1
Brown is for fan #2
Blue is for AC override (Which I don't want so it won't be used)

The relay has red, black, yellow, green, and brown.

Red is power.
Black is ground.
Yellow is to fan motor(s)
gree is not used
Brown is for AC override (not used)

This is what I don't understand, now the instructions say that if using dual fans that draw more then 20amps that the relay is required(which is beat, because when buying the kit, it says that for dual fans a relay is required, it did not mention that the relay was only required for dual fans requireing MORE then 20amps) However I"m going to assume my stock dual fans require more then 20amps. I have no idea how to wire the relay into the main module. It doesn't make sense to me....do the yellow/brown from the main module connect into the red of the relay to power the relay?

The instructions on how to install the kit do not include any instructions on how to integrate the relay into the system. The relay instructions make it look like the relay can be installed alone. I'd appreciate any help.

 

 

Yep That is how I would Do It, but I would still use the Blue wire for AC override and connect it to a temp switch that goes in the passenger side head as a fail safe just in case of failure. But that is just me, I always try to have a back up.(just in case)
