I just bought 4 Baja lights from Walmart and I'm going to install them on my front roof rack. I was wondering if anybody on here had a install guide they did on here just so I can kinda see it in pics and all. I'm kinda new to electrical stuff. Can't wait to get up!

 

Also, they don't come with a relay for the switch. Do I need to get one for each switch or are these ok to run without them?
