An electrical signal transmission path is provided along the air brake hose line (29) to provide a dedicated connecting path between communication units (28, 25) on a tractor (12) and trailer (14). A conductive line (36) extends along the length of the air brake hose (29) and is connected via a conductive linkage (33). The opposite end of the line (36) is connected to a trailer communication unit (25) via a conductive connection from the trailer end of a two part releasable air hose coupling (33) which is isolated from the trailer (14) and electrically connected to the trailer end of the conductive line (36). |
