i already have 6 and what i did to make it east was run one wire of 18 gauge down the frame rail and then to connect the lights i just took my knife and cut off the rubber coating so i have bare wire exposed, then took the + from the light and wrapped it around the 18, then electrical taped it up and grounded it to the frame and it works tits... so when i get a few more i just have to mount, strip, tape and ground and its good to go.... if that doesnt make sense ill take pics when i add a few more lights...super easy and simple
