Hi all I tried finding the answers through other threads but i'm still a bit confused. The lightbar has 11 wires, one big one which I know is ground and 5 colored pairs. The pairs consist of one solid color and one with black dashes, are they all positives or do the black dashes signify ground? Also I'm going to use a battery charger to test it, should I use a fuse? If so what amp? The circuit boards inside make me nervous don't wanna fry anything. Thanks!
