The two wires coming directly from the blower motor should be + and - . Ground one and apply power to the other to test the fan, it should run full speed. Can't remember if the wires are colored, if so ground the black one. If it is hooked backwards it should not hurt, it just will spin backwards. John is correct in that there is a resistor between the fan switch and the motor for the low speed. Gary.
