AC Problem added refrigerant

i converted the old style R12 to R132 air conditioning…and started to add the refrigerant…air condition was set to maximum and was working well with the cold air coming out the vents…but i a bad leak coming from the compressor line to the vents…and it has a electrical plug that is connected to the line between the compressor and the vents…and the electrical plug is literally the one leaking and releasing pressure…

its very weird to see a electrical connector releasing pressurized air from the ac lines…the location of electrical connector is on the right side of the car near the ac compressor… the connector that is tapped into the ac line from the compressor…

can i replace this line

any body have this same problem…
