Graphic shows two views. The left part of the figure shows inserting the straight end of a tie wrap from below into the left opening on the bottom of the strain relief housing and then looping the tie up over the wires and back down through the hole in the bottom of the housing on the other side of the wires. The right part of the figure shows inserting the flat end of the tie into the connector end of the tie from right to left beneath the housing, and pulling the flat end through the connector end until the wires are tightly bound.
