The new Trav'ler control wire can go anywhere to the control box that needs 120V power. You can reuse the existing coax cables to run whatever receivers you like so no new wiring will be required other than drilling a small hole above a cabinet that's not in a slide out and has 120V power available. Easy Peazy.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
