I want to be able to turn on my radiator cooling fans at will.

I will be installing a relay under the hood from a solid power source and have my source key on only.

My question is what wires to splice into on the fan connectors for giving power.

 

Hi Walter
I put this JPEG file together that includes the Radiator Fans Wiring and the Wiring diagrams that show the associated Fuses in the related Fuse Boxes.

Those fans are a little more complicated than I want to deal with so I am just going to wire a 10" 1100 claimed CFM pusher in front of my intercooler radiator instead mounted on brackets. In the center looks to be a bit of a dead spot anyways because of how the bumper is situated. I'm taking the simple route on this one. Simple relay, on of switch in the cabin, not chancing mucking up my electronics.
