So a few things got done while I had the center piece "semi-out".
I installed a simple USB-B and USB-C charging port. I wanted one without any LED indicators or and lights at all. Plain and simple to match the simplicity of the 40. This piece is made of aluminum and seems to match the style very well (installed below cigarette lighter). I made a small sub-harness to wire these and be able to easily remove it if needed.
I wanted to use factory switches to trigger the ARB compressor for the lockers, and also for the lockers themselves. Ofer
@ofer bruhis donated a factory pull-type switch to trigger the ARB compressor (the FAN PULL switch on the upper left), so went ahead and installed that:

Also, bought the "correct" knob for the pull switch from Red Line Land Cruisers, only to find that the threads are different than the ones on the factory Fan switch

. Will have to address that later. Kudos to Red Line Land Cruisers for making these for us.
Are you adding an air compressor to your FJ40 to assist your lockers and air up your tires? We've made a combo of the three billet knobs; Compressor, Rear Locker and Front Locker,
