I just finished my upgrade. I have a 2021 Custom Trail Boss. Changed the steering wheel, added the High Country Cluster from WAMS. Used the harnessdr.com LIN Bus Harness. Everything works as advertised. Getting the steering torx bolt out was the biggest hurdle. That added a few hours to the install. I snapped a standard torx bit in half using it on an impact wrench. Had to drive to autozone to buy an impact bit. Luckily I found a thread somewhere where they said there was Loctite on the steering wheel bolt. After I heated it up for a minute or two with a heat gun, it came right out.
