2015 VNL Has 6 speakers but your harness adapter only has 4...or did I miss something

When a truck has more than 4 speakers usually one pair is used as a component pair. This means the set usually fornd in the front are wired together as a set ofr components so you radio only need to connect to 2 set or 4 speakers. Components are considered as midrange and tweeters. They are usually wired together with a crossover system that improves the sound by making certain frequencies to go to specific speakers that will reproduce the sound better. SO....... just hookup the harness the same and you will get all 6 speakers working.
