I'm at the last step of connecting red/black wires to the radio and I'm not sure where to install them on the radio. I have a 2007 Street Glide. I saw one person said to install it to the headlight and I see a spot that has a blue and black wire but I was not positive which was positive or negative wire.
Any help would be appreciated first time doing any type of wiring.
