Abstract: A dummy plug for wiring harnesses is disclosed. The dummy plug is used in an unused connector cavity of the wiring harness, thereby electrically isolating the connector cavity in the wiring harness to prevent short circuits. The dummy plug is substantially flush with the latch arm of the wiring harness, so that a pogo pin can determine whether or not the connector cavity is in use. The dummy plug has a design such that pressure blowout is prevented. A method for plugging an unused connector cavity is also disclosed, the method including the steps of providing a dummy plug having a head, a stem, and a female end, providing a wiring harness having at least one connector cavity and at least one latch arm and inserting the dummy plug into the unused connector cavity so that the female end is substantially flush with the latch arm.

Abstract: A seal for disposition between a connector and a wire includes opposed faces having at least one wire hole therethrough, an outer sealing surface connecting said opposed faces and contacting the connector, said at least one wire hole having at least two inwardly extending compressive ribs contacting an outer surface of the wire wherein the ribs have a notch therebetween. The inwardly extending compressive ribs each have a contacting apex extending from lead-in side surfaces which extend from the respective opposed faces, and the notch has a diameter less than a diameter of a connection point between the lead-in side surfaces and the opposed faces.
