I am taking on a similar project with the foot lighting and under the front seats, except I want to have the lights come on and off with the dash and headlights. Also, I want to install a RGB strip controller to change colors when the mood hits me. Any takers on where I need to tap into to get this done? I have seen a video suggesting the use of the under hood fuse panel in the circuit #43 slot using an "add-a-circuit cable and a 12vdc relay. Although this is for ignition on/off functionality. FYI, this is for a 2010 Chevy Silverado 1500 LS extended cab.
