I would put the lights where you want them, put the negative sides of each light to the closest ground point (body or frame), and run all the positive wires to one point either in the engine bay or behind the dash. Put in a relay to power the lights and a switch wherever you want to control the relay.
I have 6 walmart 55w lights. What gauge, fuse and relay do I need, I'm bad with terms and numbers with electrical but I'm pretty good at actually wiring so if someone can help me on that front that would be great.
Well 55 watts×6 lights is 330 watts total. 330 watts/12 volts is 27.5 amps total draw for the 6 lights. I would run 10 gauge wire from the battery to the relay, 14 gauge from the relay to each light, and probably 14 gauge for the relay power switch as well. A 40 amp relay would be good and a matching fuse.
Just as a reference point, my LED strip rock lights I made for $30 or so pull less than 2 amps.
Truthfully for that amount of lighting and draw you should start over and get some small led lights. I haven't ordered anything yet but when I'm ready I'm going to go led. No heavy gauge wire need and no relays, and almost no draw. Just an idea. You might be able to sell what you have. http://www.superbrightleds.com is the site.
