It is kind of a mess. My solution is to combine most those wires down to one neatly soldered connection, unless you have a reason not to do that. Most of those fused pigtails you are using have a 12ga wire on them which is overkill for most of the things I suspect you have hooked to them. Unless it's a really heavy current draw item, use a smaller ATM style pigtail fuse. That would allow you to get all of your wires into a 10-12 gage connector. There are more pricy options, by I don't see the point.
