Abstract: The electrical connector unit includes a first connector electrically coupled to a component to define a path for electrical supply therethrough for an activation and a deactivation of the component. The first connector includes a body, electrical contacts, and an opening. The body includes a surface that defines an array of electrical contact locations including one or more first electrical contact locations and a second electrical contact location. The electrical contacts extend correspondingly from the first electrical contact locations. The opening extends from the second electrical contact location to fluidly couple with an interior of an enclosure encasing the component. The first connector is configured to receive a second connector configured to facilitate passage of a fluid through the opening to create a pressure differential between the interior of the enclosure and an exterior of the enclosure for performing a leak testing of the enclosure.
