Wiring 5 hp compressor pressure switch

motor has black, white and ground. If using my clothes drier receptacle would i use black, red, white and ground. Does the other 2 contacts of the pressur switch use black and red ie no white to give the 220 or do you use the white and stack the black and red to the contact. 4 CONTACTS MOTOR WHITE MOTOR BLACK AND OTHER TWO ON SWITCH ?

I've posted this Mr/Ms mgdeathe in the hope that an electrician can respond.

I'm not one, and have too high a respect for the speed with which 220 volts can kill (120 volts too for that matter) to offer you wiring advice.

Cheers,
