Light Bar Install 2010 Wrangler

Hi guys! I need a small bit of help. My dad bought me a 50" light bar for my JK that I saw on the internet. It was cheap and now we know why: no brackets and no wiring harness:( So, I've taken some summer work money and bought brackets and $80 worth of wire/connectors/relay/switch/inline fuse. This has become expensive and if I could do it over again, I would have bought a nicer light bar. Anyway, my dad is helping but wants me to figure this out. I have wired everything on his work bench, installed the switch to the dash, and run all the other wires. My question is this: my research (youtube) tells me that there is a wire from the switch that needs a "contstant hot" connection. Do I wire this straight to the battery (without a fuse) or is there a wire that I can grab and tap into? Thanks for your help! Shaina
