You just have to unbolt the 2 10s and the 1 9 in that picture. The 10s are at the sides. Alternatively you might be able to pull the side cussion enough where you can open a gap bigenough to feed something through like a dowel or something and then just tape your wire to it and pull it through.
I wish i were close by because its a really easy job.
