No worries. I ended up buying one from summit. It's got a power lug on one side and spots for 4 mini blade fuses. I figured that's all I'd need but they make them with any number of circuits you require. Even comes with a protective cover and LEDs to tell you when the circuit's live.
I want to add a fuse block. I’m looking at this. I struggle with wiring bad!! The left side in the pic. Red. Has power full time. The blue when the key in on. And the purple and right side have power only when power is cranking. The block I have has 6 fuses and 1 spot to attached power. I want these to be switched fuses. Help please.
