I bought the volume controls from the dealership. I also bought the harness. What I am missing is someone willing to pop that cover and see if it works. I am willing to donate what I have for the cause. They are not too expensive. I have a 2020 Trail boss custom.
I have been told you need to be mindful of the air bag.
I got the parts, do you have the talent.
Who wants to try it out?
