BlueSeas is what I used for my four switch panel..... some positive and negative busbars...marine wire of correct size....connectors and heat shrink stuff. Some wiring guides suggest a specific color wire for different things.....i stuck with black and red. I am no electrician but read up on it and did all of my wiring, everything works perfectly. My bilge pump came with its own switch.....has auto and manual settings and is separate from the Blueseas panel. My usb charger went into a 12v socket just below the ignition switch.
Rockfish Joe is spot on with his advice as always.
