If you haven't found anything yet, etrailer.com has everything you need. Just input the year of your jeep and it will show the base plates, the wiring basically everything. Depending on the year of your jeep you might need a kit to keep the cigarette lighter socket energized when the vehicle is off, if you do, here is what I found that works for me. I have a 2019 Jeep Wrangler Unlimited.

Cooltechllc.com and the part number is JL18CT12VP installs under the hood in the fuse box behind the battery, no disassembly of the interior required.
Hope this helps.
