I bought a 3000 cfm electric fan new off ebay, great deal until I open it and find only a fan and temp switch, no mounting hardware, wiring, connectors, relay or fuses, and most of all no install instructions! please help! How should I mount it using factory shroud to direct air? how should I wire it up, it is set up to turn on at 180* thru the temp switch. Should I mount the tempreture switch in the intake port close to the thermostat? Any help would be great.
