Pillar shield for securing a wire harness

A plug inserted into and enclosing an opening within a wall of a hollow post and securing a wire harness running within said hollow post, comprising:

• at least two locks projecting out from a surface of said plug and securing said plug within the opening, at least one of said locks being located at or near a first end of said plug, and at least one of said locks being located at or near a second end of said plug, said locks resiliently engaging an edge of the opening and aligning said plug within the opening along a first axis;
• at least two tensioners projecting out from said surface of said plug and resiliently engaging the edge of the opening and aligning said plug within the opening along a second axis, at least one of said tensioners being located at or near a first edge of said plug, and at least one of said resilient tensioners being located at or near a second edge of said plug;
• at least one stabilizer projecting out from said surface of said plug and resiliently engaging the wall, thereby exerting tension within the plug along a third axis;
• and
• at least one fastener for securing the wire harness to said plug;
• wherein the at least two tensioners and two of the at least two locks are hook shaped leaf springs;
• wherein the at least one stabilizer includes at least two tab shaped leaf springs extending in substantially opposite directions from one another.
