I have changed bars on my 2019 three times, the last set was the Monkey Sport Bars. You do not have to disassemble any of the wiring, HD started using small connectors in 2016, in fact when I changed bars on a 2018 it was the same. As for the Sport bars, they are very easy to wire and install. I did my set a few months back after a month I decided to change heated grip, from Kahuna (which this just reminded me I have to sell) to another set. I decided to try changing out the heated grips with the bars still on the bike and the change went very smooth. As I said the Monkey Sport Bars where very easy to run the wires. It's an easy task and I believe you will not have any problems, just take your time give and take while running the wires. Good luck and post up some pics when you are done.
