Hey Bonnie!
There's no reason you couldn't install and use the Roadmaster Battery Charge Line Kit # RM-156-25 on your '22 Jeep Wrangler JL. It's not going to have any effect on the Jeep's electrical system.
Now with that being said, you SHOULDN'T need the kit, as the battery on your Wrangler JL shouldn't drain during proper flat tow setup and use. This is according to Roadmaster. Do you have everything else you need for the full flat tow setup? If so, where are we heading first?
