Abstract: A reduce cross-talk wiring harness and method for accomplishing same. The wiring harness is used for routing signals from a bus and tag housing to a controller, and for routing signals back from the controller to terminators in the bus and tag housing. The harness includes an input pair and an output pair of bus and tag ribbon cables. The cables in each pair are of essentially the same length. Each pair has a combined bus and tag connector attached to one end, and individual bus and tag connectors attached to the other end. The input and output bus and tag ribbon cables are grouped together for at least part of the distance between the controller and the bus and tag housing in such a manner that at least one of both bus cables or both tag cables are adjacent one another, to reduce cross-talk between the bus cable of one cable pair and the tag cable of the other cable pair.
