How can I install an extra cable outlet on wall that l already has an existing cable oulet and line? Currently, I have a cable outlet on the other side of the wall where I plan to intall a flatscreen TV. The problem is it is not hooked up to my cable line. I would like to , again, place another cable oulet on the wall where there is already an existing cable line and use a splitter. Please help. Any suggestinons?

Not sure exactly what your asking.

Home runs (runs to a central location) are preferred. A splitter is fine.

Are you asking, how to fish the walls and run the cable?
