Sorry no video yet, I have been traveling for work a lot lately
I did add an “add a circuit” for the power to the ECXU using Power Outlet 1 from the fuse panel below the steering wheel (All of the fuses in the rear always have power). The wire is easy to tuck under the plastic trim along the doorframe and around the rear seat, and works great. No issues with power loss after the car has sat for 2 weeks.
