Help!! How to remove fuse block

[txkfx400]

I have been having some weird problems. Speedometer and cruise would quit and ABS light and OD light on. Sounded like VSS, but I would also lose my turn signals, AC and temperature control on heater/AC. I would turn the truck off and restart and normally the problem would go away. Then that stopped fixing the problem and banging on the dash(don't ask!!) would fix it. It was getting more frequent. I started messing around and found that if I jiggled the bundle of wires that goes into the back of the fuse box on the right side (looking at it from the driver's seat) I could get the problem to go away or rear it's ugly head. That is where the problem seems to be. My question is this. How do I remove the fuse block? I removed the 2 bolts and 2 nuts and got the box free from the dash. There are 2 bolts on the back of the box that appear to hold on some sort of cover. Do I remove these bolts and/or covers. I really just want to gain access to the rear of the box so I can see if anything is loose or coroded. Is there a connector under these covers or just wires going to their respective slots in the box? By the way, the truck is a 2001 F-250 7.3 4x4 Crew Cab. Sorry for the long post just to ask about the fuse box, but I figured it might help someone else with the same symptoms.
Any and all suggestions would be greatly appreciated. Thanks in advance!!

By the way, I did search. Looked through 27 pages and could not find any info. I may have missed it somewhere.

I just removed mine to do the fog light mod. Just open up the fuse box like you wanna change a fuse and theres 4 bolts (10mm head or so?) holding it within the dash. Just unscrew them and fish it out the hole

Thanks!! Do you know what the 2 bolts on the back of the box are? They seem to be holding on 2 covers. Is there a harness under these covers? Thanks again.
