thanks. Yes, (I forgot to specify) via the factory 4 aux switches. I did see on another thread these switches can be switched or battery via unconnect programming.If you have a JL with the trailer tow package and the factory switches, there is internal wiring (passenger side floor board area) and external wiring (under the hood).
I would think it is best to go right to the battery. When I installed my CB, I used the internal wiring and one of them goes straight to the battery and is always hot (not on a switch), and used a ground location passenger side floorboard.
Just need to remember to power off whatever device is connected directly, just as you would need to remember to move the switch to the off position.
I am interested to see what others have to say on this subject.
Thanks Jeff. Feedback definitely a concern. Want to do this rightGood Luck on your install. Take your time. I sold my radio and antenna with my JK and have not figured out yet what to do with my JL. Wiring directly to the battery is generally recommended to reduce interference from the vehicle to the radio, and from the radio to the vehicle.
