Hey Brian,
I'm not the electrical engineer so I made sure the Jeep was already wired

The factory bracket, however, is clean looking and doesn't extrude out as to get caught on anything. Most of my trailering is with a 7 foot light utility trailer that has a four pin plug. I purchased a 7 - 4 pin plug-in adapter for about 10 bucks at Wal-Mart that I keep attached on that trailer most of the time. I'll detach and throw it in the back of the Jeep when needed for towing someone else's 4 pin trailer. Also, my camper is a 7 pin so I'm already good to go on that one. Hope this helps.
