there is a possibility that one of these is wired into your electric fan circuit....not shown...but a component~_____http://www.jcwhitney.com/engine-cooling-thermostat- switches/p2000903.jcwx

Damn! There is NO temperature sending unit on this car that operates the fan!!! There is a Cylinder Head Temperature Sensor on each head that the COMPUTER uses to determine when to cool the engine. The computer controls the fan EXCLUSIVELY! I work on a fleet of 800 Ford Crown Victoria Police Interceptors: 2002 to 2013 - same car - different decals - we have cooling fans fail regularly. THE COMPUTER CONTROLS THE FAN BASED ON CYLINDER HEAD TEMPERATURE AND AC DEMAND. NO THERMOSTATS - NO SWITCHES - JUST THE PCM.

And where did you get that ancient (and incorrect) picture? The 2007 4.6L V8 is a coil on plug motor - no plug wires or coil packs - OR ECT!
