Please help me with the location on of the high side for checking the coolant level. I believe it is large black cap or cover on the right side. Thank you for your help.

There will be a low side service fitting on the accumulator on passenger side. The high side is not where you add refrigerant unless you evacuate and charge with equipment that adds by weight with system off. For pressure diagnosis you attach a hose to the fitting on back of compressor that is a pain the butt to get to.

what size hose is used and where do you get it.

The standard hoses that come with the pressure dials don't fit it
