Well ive managed to get the fuseboard sitting in the outer casing but its a very tight fit...... as in i actually had to push down on the lid to get it to close properly rather than just clipping it on, is this how you had yours fitted or did you get it sitting in there quite nicely? The wires that go into the fuseboard are quite jammed up underneath, bit worried about them cutting through where they rub so tightly against the hole in the bulkhead.
Also didnt have to mess around feeding the entire loom through the fusebox hole in the bulkhead as the old style fuseboard just about squeezes through the new style hole in the bulkhead so just poked it up through from inside the car, which was nice!
