Fuse box (central) Additions

[Classic 375]

Hi just like many others here i would like to add a component (such as a Dash Cam or other) but i don't want to use a Piggy Back Fuse holder/s. I would much prefer to access the output side of  a fuse and add a wire. I can drop the fuse board alright but whilst laying upside down with a head torch which only shines on the spot when i cant actually see where it is and only being able to get my hands on things when i can envisage and use braille to feel for what i'm doing is not making the task any easier. 

Simply put .. there seems to be a cover on the fuse box ? have i got to remove all the fuses and whatever else is plugable in order to remove that cover?

If i get to the terminals of the fuses  will i have enough room to get a soldering iron in to solder a wire onto an out put?

Or is there room for a push on connector.

Thanks to anybody who responds
