You got it, sir.

I will give you my $600 LCB/compressor R&D mistake for FREE. If you go the route of an LCB, make sure it is built for the operating voltage of the compressor you intend to run. Off the shelf 12V LCB's are usually set above 12V and out of the operating voltages of a lot of 12V DC compressors. The compressor will run wayyyy to fast and pump failure will occur prematurely.
