A vehicle body structure includes a first body structure defining a first interior cavity and a second body structure defining a second interior cavity, with one of the first and second body structures being pivotally connected and movable relative to the other of the first and second body structures to define an open configuration and a closed configuration. A base member is fixed to the first body structure. A guide member is fixed to the second body structure. A channel member is movably received by the guide member. The channel member has a first end rotatably fixed to the base member and a second end positioned within the second interior cavity. A wiring harness passes through the channel member from the first interior cavity to the second interior cavity. A first sealing structure sealingly engages the base member and the first end of the channel member.
