After that you take the wire and run a long strand from the light bar all the way around your motor casing to the battery which is usually about 6 to 7 foot. When you get to the battery you strip off the top plastic layer of the wire and twist it around your battery cable, then stop and get about four more feet from the box. After you have hooked the wire to the battery you need to connect the other wire to the same wire you had before and connect them at the battery. Go to the dash of you truck and open up the driver side dash panel that has your fuse box in it, take out the fuse cover that says 30amp and put the fuse that is needed into the slot. Now that you have done that take the loose wire that is hooked to the battery and run it from the battery to the back side of your fuse box. The last step is you are going to run one more fuse from that same fuse to your switch that is mounted on your dash board.
Now since you have followed these steps you are ready to turn nigh time into daytime with your new correctly assembled and mounted led light
