Hey Guys,
I'm not too familiar with hooking up electrical items and I want to make sure i use the right gauge wire, i have two led strips that i want to hook to a switch. What would the proper gauge be for this? Also can i tap into any wire on the fuse box that gives me a constant 12v? Would it be best to tap directly into the wire or to use spade connectors to run like so:

fuse box -> fuse -> switch -> strips - > fuse box

Thanks ahead of time
