There is no blue/white wire on the HU. It's just the Blue. According to the head unit wiring diagram, the blue can connect to an amp or power antenna, or insulate if not used.then forget about oranges lol
blue is similar to blue/white, but applies only on the AM/FM source, use the blue/white
The harness does not have blue/white wire either. Just the blue. So logically I just soldered the blue wires together anyway, even though I don't have a powered antenna.
