I like the finish of running the wires in the wall, if you check this thread on my installation you will be able to see pictures of how the walls are constructed and it may give you ideas on how to fish your wires. What locations are you trying to run wires to/from?
actually, the pictures are on my profile gallery.
Notice that the ceiling is where the original bundle of wires runs, you may be lucky enough to get a fish tape down there to the front A/C and pull your wires to where you need them.
