Me that looks like more work and more places for a connection to go bad... Instead of every wire running directly from the fuse box you have to plug every single wire into the fuse box...
Just like I don't like the factory Ford and Chevy fuse blocks that have connections on the backside of them inside the firewall. I think Ford had it right by running the wires through a hole and directly out to the sources from the fuse box and having less connections. Of course it's not easier to plug and play it like no fun Chevy is but less places for a bad connection...
