Audi A4 1999 1.9TDi Oil pressure light on continously. Engine sounds fine. How do I remove electrical connector to remove switch and check pressure with a gauge?

Of which low pressure switch are you speaking? Engine oil pressure switch? If you're checking that, remove the oil pressure sending unit and temporarily put in an oil pressure gauge. If you're checking the AC low pressure switch, pull the switch from the AC low pressure line, Jumper the switch socket and see if the AC compressor comes on. If it does, you either have low refrigerant pressure or a bad switch. If you KNOW the pressure is up and everything else works, you have a bad switch.
check fuel pressure first
Not usually....No. Take it in to AutoZone and have them check the codes for you.
It means that the oil pressure switch is showing low pressure.
Should be around the oil filter, check the manual if not there.
