I just installed fog lights on my 2021 2500 Tradesman this weekend. I do have the up-fitter switches and used one since my push button feature turns on the cargo lights. I made a nice heavy duty harness using 14AWG wire. I could probably help you with how I made it if you knew what your plugs are for the lights. You'll need a relay, and inline fuse as well. I didn't need those as the up-fitters have their own, but I put an inline fuse anyway.
