My comments are based on my experience with a 2015 Jeep Wrangler 2dr with automatic transmission. You do not need a charge line to the Jeep, you will need to install wiring for tail, brake, signal lights. You do not need to leave the key in the ignition so after setup put key in pocket. At least on my year model you not need to pull any fuses. You do not have to disconnect the battery. One of the easiest to setup and use, cost effective tow solutions is the Ready Brute Elite package. Give them a call and they can inform you of exactly what you will need.
Simply hook up the tow equipment, put transfer case in neutral, transmission in Park, remove key and go.
