The logic programmed into HarnWare for Databus harnesses is significantly different to that used for “normal” wiring harnesses. When the Design Wizard searches a drawing and finds a databus part, it switches to the Databus logic. As databus harnesses don't, for example, require the “Add Wire” function, this option is excluded from the design wizard list. Normally databus harnesses should be constructed using one of the metric or imperial databus HarnWare templates. Unlike the normal HarnWare templates these don’t include a wire list page.
