A wet connection system including a first connector configured to connect to a first control line. The first connector including at least one first pathway arranged to fluidly communicate with the first control line, and a biased movable plug movable within the first connector; and, a second connector configured to connect to a second control line. The second connector including a second pathway in fluid communication with the second control line and a biased sleeve movable within the second connector; wherein the first and second connectors are each pressure balanced to prevent internal control line pressure. External borehole pressures from moving the plug and sleeve from their biased positions blocking the respective first and second pathways in the disconnected condition of the wet connection system. Mating of the first connector with the second connector moves the movable plug and the sleeve against their bias to fluidically couple the first and second pathways in a connected condition of the wet connection system. Also included is a method of pressure balancing a hydraulic wet connection system in a downhole environment.
