1. An electrical coupling apparatus for interconnecting respective first and second multi-conductor electrical circuits of releasably interconnected vehicles, such as an automobile and trailer, and having provision for assuring a desired connection between the several conductors in said first and second circuits, said apparatus comrisingpolarized coupling means for releasably interconnecting said first and second circuits with a fixed predetermined arrangement of the several conductors thereof, anduniversal coupling means interposed between said polarized coupling means and one of said first and second circuits for selectively and releasably interconnecting the conductors of said one circuit and the conductors of an intermediate multi-conductor electrical circuit, said universal coupling means comrisinga. an electrically insulating support,b. a plurality of spaced apart, electrical contacts carried by said support, with each conductor of one of said one circuit or said intermediate circuit being electrically connected to separate ones of said contacts,c. a plurality of individual terminals, with each conductor of the other of said one circuit or said intermediate circuit being electrically connected to separate ones of said terminals,d. means for releasably interconnecting each of said terminals with any one of said contacts, whereby said terminals may be selectively interconnected to said contacts in any desired arrangement;

  • ande. electrically conductive clamping means for releasably attaching said support to the frame of one of said vehicles, said clamping means being electrically connected with one of said contacts for thereby providing a common ground for the two vehicles.
