Electrical connections between a cable connector and an electronics module-that has a corresponding panel connector-are made/broken quickly and easily with a light, low-bulk half-shell that is an exclusively mechanical, nonelectrical intermediary from connector to module. A rack receives and holds the module, and a connector holder, formed in the rack, receives and holds the cable and panel connectors aligned. A cam is associated with the rack or module, and a cam-follower with the other-preferably in duplicate opposed sets. A single, one-hand-actuated lever on the rack or module operates the cam or follower to bodily shift module vs. rack and engage/disengage the connectors. Preferences: each holder easily and quickly engages/disengages from a corresponding cable connector. Typically a module weighs at least several pounds. The cam has a concave arcuate segment to draw the module in and seat the connectors, and a convex arcuate segment to eject the module and unseat them. The lever hinges to the rack; the cam is formed in the lever; the follower is a post projecting laterally from the module. A latch-pin fastener on the lever helps secure it and the rack and module fully engaged. Offset alignment rods project forward from the module through holes in the rack to prevent inverted installation. The method inserts the module partway into the rack and then operates the lever with one hand to draw the module in and seat the connectors.
