Warn and other vendors offer Quick Connect cables and fittiings for front and rear mounts. You could leave the wires in place all the time and connect the winch when needed. https://www.amazon.com/WARN-32966-Quick-Connect-Power/dp/B00029XFG0
This sounds great as I have been delaying on wiring mine up because of how complicated the instructions were to connect under the hood. Did you wire in parallel? Can you share more details? How did you connect to the lamp circuit? I like the idea of avoiding the wire from side to side.
I bought a front receiver hitch to allow this. You do not have to get a new bumper for this. https://www.autoanything.com/towing/curt-front-mount-trailer-hitches Installation instructions are good.
You may want to try mild off-roading with your stock JLUS first so you know what direction you want to take. You may be surprised at how capable it is and also you will learn what aspect of off-road you enjoy more such as rocks, mud or even overland. I'm sure others will answer your questions...
