So let me cover both issues here, starting with the wire.
CIM motors have a slightly higher temperature insulation and in practice would be wired to a long length of wire. (They were originally designed for trailer tongue positioners as I remember.) In our application, you can run #10 to them if you so desire. The short length of higher temp wire still keeps them safe for our purposes.
The output port of the compressor is supplied with a check valve to prevent system pressure from bleeding through the compressor. I haven't examined one in a while so I don't remember if that fitting is part of the check valve. I will try and check tonight before we mount the compressor (maybe).
