Well, this is not TW/Spectrum's first rodeo. If they haven't been able to take a hint about discrete power by now then they fully deserve it. The reality is, it costs them nothing to implement, literally.

Since I am making no real modification to their box, other than soldering some wires onto existing joints, they will have a hard time proving I was in there to start. There is no wire cutting etc. My circuit is harmless if installed correctly. And the entire process is easily reversed to make it like OEM again. When I return that box, for whatever reason, they will have to get forensics experts to testify that someone was in there :)
