John,

No problem just installing the compressor. You will have to ensure that you have a pressure switch AND and compression relief path.

That may already exist in the coach.

Or you can easily plumb your own.

I am planning to just install compressor and use the Valid electrical/pressure control. I am not sure what to do with the line that goes to the electrical switch. see picture shows two lines at junction. one going under switch. second picture shows under the switch.

Hope this helps
