Best place for efan thermoswitch

Thanks for all the feedback.

TTT-you're right and it was my same belief before going in the machine shop. The machinest convinced me that the radiator would match temps of the engine. Fortunately I caught them before they opened up the bottom port on my koyo.

What I'm thinking is swapping the OEM thermoswitch for my Summit Racing. Splitting off the signal from that. One going to the engine harness and the other going to a relay to control the taurus efan.

I like the idea of tapping into the factory wiring for the relay, but I'm also concerned about the draw the Ford fan creates. On high the fan can practically lift off the ground.
