I was not happy with running the wires along the stringer supporting the luggage locker floor. They were attached by cable ties along the stringer which were touching the side of the locker floor. I bought some cable tie supports which I have riveted inside the stringers with 3.2mm/1.6mm aluminium open rivets I bought from the local hardware store. They have a much flatter head and support the wiring much better and will not fail with vibration and rubbing, which the cable ties may have in time. I also sanded the rivet heads down further on the stringer so the floor would seat better.
