Help! Replacing body wiring harness how to remove lower portion of module box?

[rsmoluch]

We are replaceing the body wiring harness on a 1992 600 SEL and can not seem to remove the lower portion of the module box. There is almost no room in this area, and 4 bunches of wires makeing the removal impossible. On the passenger side of the car there is a heavy duty bracket that holds the upper portion of the module box one-but really seems to be in the way when trying to remove the bottom portion. Does anyone know how to get this off? Maybe this is not important, so any other general advice as to how to remove the bottom of the box would be great. In the pictures the bracket is the dull grey metal just under the hood arms. There were four bolts in the side that have already been removed, but we must be missing something. Again, any general advice would be helpful.
Thanks, Renee
