If it's just a 4-Way Flat connector like the T-On # 118786 then I would be surprised to see that much power being pulled to the back of your 2020 Jeep Wrangler Unlimited, but if you have a 7-Way like what we find with the Wiring Kit # ETBC7 then 3.6V on the 12V power pin isn't out of the ordinary and you'll be fine.
Attached are photos showing the functions per pin on both a 4-Way and a 7-Way connector for you to reference.
