Because of their height and shape Jeeps generally don't need a stone protector. I towed my Jeep Wrangler for several years without one and never had any problems.
Blue Ox tow bar is the best in my opinion, get the set of locking hitch pins to go with it
This is where you want to go for a wiring harness for your Jeep, easiest and best on the market to use.
