Congratulations on the Seneca - we love ours. Regarding the TV - remove the outlet that the TV is plugged into and it should be obvious which wire to cut - the one going to the solenoid glued to the back of the outlet. I cut mine and put a wire cap on the feeder.
The issues we've had so far are:
- Stripped the gears in the step motor by being impatient and not waiting for them to fully deploy before stepping on them. Stupid, stupid
- Some sort of adhesive tape on the upper corner of the main slide attached itself to the "sweeper" seal (rubber seal going around the perimeter of the slide opening) and started pulling the seal outside. Had to have the seal replaced by the dealer.
- Main slide was dragging on the floor and scratching it. Required minor adjustment and replacement of a couple of floor tiles.
We tow a 2014 Honda CR-V and it does great. Enjoy your new coach!
