I also added LED strip lights in the rear under seat storage, under the sink and in the ski locker. They are all wired to the “cabin lights” switch on the dash. The strip lights under the sink and seat storage extend in to the side pockets illuminating that area also. We love this set up.
Can you share details on how you wired this up to the cabin light switch? My son and I were just talking about this exact type of setup..
