The codes they found were in the fake licence plates seen on 2 cars that appear in the commercial. I call attention to those and others, and some other Occult symbols in this video I published to our YouTube channel. The commercial has Neo Nazi codes 14-88, 84 and 39, and loads of SS! I don't call it out, but you will find Monarch/ MK-Ultra imagery too.
