I didn't tighten the cords but tonight when I get home I'll take a look if I'll be able to tighten it without pulling too much, I wouldn't want to damage the connection. It's funny because I too thought that there should be a slot cut out. I initially ran it the way you did, but I ended up routing it to where I had to run it up the back of one space loop it around the front and back down a second space. Hard to explain, I'll take a pic and post tonight to show. Thanks for the reply.
