What you have: Basically, when power gets to your lights, it goes to the positive on the first, then the first negative goes to the second positive , then that second negative goes to the third positive etc until the last ground just gets grounded.

What you need: You want to have the power go to all the positives, and the negatives to the ground. I don't know how good of a ground the rack will be though, if it's only connected by a couple bolts, I would run a jumper to the frame of the truck from the back rack, and if they're big lights, another jumper from frame to the battery.

 

Basically you need 3 fuses and 3 switches. The lights should only ever be hooked up by pairs. I'd have the two outer lights together, the next two in, and the center pair. This will brighten them up considerably

 

Thanks dude :d big help really
