I have a new 1990 300zx na where the fuse box was relocated to behind the driver side marker light. Pita to get to. How difficult is it to move it back to the top? Can I just pop the units out of the plastic housing and pull it back through?

 

Is it the factory one? Why was it moved?

 

It is the factory on.. Why was it moved? I wish I knew. Lol. Like that when I got it.
