It's the firewall on the inside, there is a rubber plug that goes in the hole. What it's for I don't know other than to provide a hole for just such a thing as Shockwave is doing.
I ran a power wire through this same hole and it may of been coincidence but my remote range dropped to where I had to be standing next to the vehicle to unlock the doors. I pulled the wire out and the range returned to normal. The antennea is right above that hole so I'm guessing there was some interference.
