Wire management system for tonneau cover

A foldable panel assembly comprising:

• a first panel;
• a second panel, the second panel being located adjacent to the first panel and being rotatably attached to the first panel along an interface therebetween for rotational movement about an axis of rotation, such that the foldable panel assembly has an extended position and a folded position, the folded position being the first panel rotated to stack onto the second panel;
• a wire management system, the wire management system including:
• a junction box disposed with the first panel and having an electrical connector,
• an electrical wire, the electrical wire being attached to the electrical connector of the junction box and extending from the junction box over the interface and to the second panel,
• wherein:
• in the extended position, the electrical wire has an amount of slack sufficient to allow the electrical wire to move relative to one of the first and second panels,
• in the folded position, the amount of slack in the electrical wire is reduced relative to the extended position and the electrical wire is taut over the interface relative to the extended position,
• whereby the first and second panels may be folded onto one another and unfolded relative to one another without pinching or straining of the electrical wire during said folding and unfolding.
