Hiding the carkit cables

I am looking for a smart way to hide the cables of my carkit. Up till now I have used scotch, but it looks cheap, because you can see the tape (see pics). So I thought about putting a little glue on the wires, but before doing something that is permanent I would like to ask for better solutions.

When I installed a satellite radio kit in my Nissan Maxima, I used a couple of small plastic "spatulas" (used for home repair) to push the wires behind the interior pieces, as well as lift the interior pieces as necessary. The wires are now not visible, but they will also easily pull out should I want to remove the system at a later date. Just be careful and very patient, and you should be able to hide those wires without using glue or tape.

Putting it behind my roof interior was no problem, but on the side, where the airbag is, I cannot get behind it at all.
