A preferred embodiment of a cable harness assembly includes a shielded cable comprising a first and a second conductor for conducting a pair of differential signals, and a generally planar board having a first and a second electrically-conductive trace formed thereon and having a first and a second major surface. The first trace is electrically coupled to the first conductor at a first location on the first major surface and extends along the first major surface to a second location on the first major surface. The second trace is electrically coupled to the second conductor at a third location on the first major surface and extends along the first and the second major surfaces to a fourth location on the second major surface.
