Electrical assemblies including various complementary electrical components and plurality of cables are provided. Components of the electrical assemblies are configured such that respective signal conductor ends of the plurality of electrical cables can be isolated from one another and placed in electrical communication with the complementary electrical components using a conductive material. In accordance with some embodiments, the electrical assemblies include organizers that define respective pluralities of cavities and are configured to be attached to the complementary electrical components. In accordance with another embodiment, a leadframe assembly can define a plurality of cavities. The cavities of each of the pluralities of cavities are isolated from each other such that respective signal conductor ends of the plurality of electrical cables can be inserted into respective ones of the pluralities of cavities and placed into electrical communication with the respective complementary electrical components by filling the cavities with conductive material.
