Abstract: An electrical connection box assembly provided with a projection extending outwardly thereof. The projection is preferably in the shape of a semi-circular channel and a wiring harness passes from electronic devices within the box, through a cut out in the front wall, and rests in the semi-circular channel. It is retained in the channel by a tie strap which is located between two retaining elements spaced apart approximately the width of the strip and forming planes parallel to the front face of the box. In this manner, the tendency of the strap to slide along the projection is eliminated and the strap can be tightened by pulling straight up thereon, thereby minimizing the space needed under the hood to install the device.
