So I have a 2021 Trail Boss custom and am looking to upgrade the steering wheel so I can get the volume and talk controls. Can someone list off all the parts needed? I’m a little confused after going through every post so if someone can provide a summary in one post that would be awesome. Also if there is a video showing a step by step at all that would be awesome too. I watched the video tied to this thread but it didn’t necessarily do a whole lot in terms of showing how to do it. Thanks in advance!
