Bests & Worsts Reviews from Amazon

Saw a lot of questions about how to wire it to a 12v system so I thought I'd take some pics. First cut the cord off the power source on the output side (side with round piece you plug into the controller). Once you cut it off, carefully slice the cover open and inside you will find a red and black wire. This will be your power and negative. The power source is only for converting 110 to 12v so you can throw it out. I crimped ring terminals on these wires and connected those to the battery in my camper. The round end plugs into the controller. Screwed the controller on the under carriage and the stuck up the lights. Super easy. I even had a foot left over I stuck under my kids Jeep using a spare controller I had for another project. I just soldered in a power and negative off the battery wires. Time will tell how it holds up but it's cool looking right now.
