I have found that this forum is invaluable. Installing a crank up satellite dish on my 335. I know that there are cables on the roof in the "fake sewage vent" but before starting I have seen a lot of traffic about where they go and how they are connected. Fortunately I communicated with JimF since he had a post about accessing the cables from the center overhead cabinet. PM'd him and he told me to pry up the lower cabinet back in the center cabinet.
Well...I did and it was just as he indicated. Here is what I found after prying off the trim (3 sides glued to the panel) and prying out two staples on the upper side of the panel. The false panel covering this hole was not glued in any way. Obviously a couple of screws could have held it into place and made it easily removable. I can imagine how long it would take me to get an answer on this from the factory!!!!
Now, I didn't make that rough cut, the factory did and covered it with a nice clean panel. By the way, those 3 cut cables in the foreground are the cables from the roof and clearly don't go anywhere anyway. Splitter had some slightly loose F connectors as well.
Now to pull the new cables from the roof and push them into the passenger side compartment.
A picture is worth a thousand words, this forum...millions!!!
Thank you JimF!!!!!
