Yep thats where i ran mine as well, try and find the thinest stiffest wire you can get and make sure there are no edges on the end you are feeding through so it can't grab on anything. Then what i did with my brother was make a loop around the power cable on one end with the wire and then tape it so it cant slip out. I hope you've got patience or alot of skill because it took us a while to get it through.
