So it would be ok connect the two reds wires into one wire with a butt connector, same with the ground? also, can I connect the LCD power wire(s) and control module power wire all into my radio ACC 12v yellow wire harness which has constant power? I thought the "in" had to be from a headlight switch wire or headlight wire so it would dim when I turned on the headlights, interior lights can be used instead???
