Abstract: Modern internal combustion engines require the provision of an electrical connection to electrically controlled devices disposed within a cylinder head cover. Prior mechanisms for providing such electrical connections have been complex and awkward to assembly while maintaining the desired sealing characteristics and, in many instances, have not provided a ready way to remove the cylinder head cover without breaking the electrical connection to the electrically controlled devices. To address these deficiencies, a readily usable and fluid-tight connection arrangement and path through the cylinder head cover can be provided by way of a first connector that is moveable by a suitable tool to engage the internal surface of the head cover adjacent an aperture in the head cover. A second connector can be mated with the first connector from the exterior and engages the exterior of the head cover.
