My team is trying to hook up the ring light. I already have a terminal strip in place, but we do not know which side is positive and which is negative. I have looked on andymark, the vendor's website, and many different threads on chief delphi. Do you guys know which wire is which? I was assuming the one that is tinted copper is positive, but I don't want to plug it in until I know for sure.
