I've did everything to convert over to non AC and I did a search on how to wire up the second fan to turn on but most of the setups I saw were with AC. I guess I could folow it but just not sure. I kept all the wires/plugs intact incase I wanna change back to ac. All I wanna do is make it so the 2nd fan can be turned on automatically or maually. Can any one point me in the right direction, thanks.

 

I forgot to mention now that that everything is taken out the 2nd fan runs continuously. Which plug do I have to hook up and where to get it to shut off? When I get the right wires could I just run them through the firewall into the car and use these wires to for a manual on/off toggle switch?
