If you are asking where you should position the new fuse block, you want it where you can get to it without standing on your head to service it in the future. Since you say you are going to run an emergency brake, which I think means on the left side of the steering column, I would use the right side kickpanel for the fuse block. You can make a removable cover over it, like the new cars have, that can be easily removed to get at the fuses, yet it is hidden most of the time.

BTW, that car is super clean inside.........nice job.
