Any folks know 220 wiring ?

My preference is to work with the compressor...less to p off the wife.

My compressor wires are hotblack/white and green ground.

I will do a walk through as Ihearold suggested (thanks !) but I am still confused as to what to do with the neutral ?? Split the ground between the two ? ..or pull the ground off (on the 4 plug) and ground to the compressor and used the green as the neutral ?
