Another thing you will need is to hook up the Jeep's brake and turn signal lights to the Georgetown when towing. There are several ways to do this. You can use external stick on lights, add new bulbs and wiring to the existing tail lights, or run wires to the existing bulbs.
An easy way to connect to the Jeep's existing wiring is to use a kit such as the one sold by Cool Tech:
JK Tow Harness Deluxe Kit - CoolTechLLC
It's a little pricey, but high quality. The folks at the Wrangler Forum really like it. On 2008 and newer Wranglers you do not need to use the kit's battery disconnect. I made my own version wiring harness for a lot less using a trailer hitch lighting harness for the wrangler. With the kit or my cheaper way, you do not cut into the Jeep factory wiring at all. The new wiring harness simply plugs into the Jeep tail light connector at the driver's side.
Another tip is that you can run the tail light wiring inside the Jeep's box frame so it is protected. The "professional" installations that I have seen simply used nylon wire ties to attach the wiring wherever it was convenient under the Jeep. Fishing the wiring inside the frame was not difficult, as there are several drain holes along the frame. Just pull the wire harness from one hole to the next. I also used split loom tubing to provide additional protection for the wiring. Installing the wiring inside the Jeep's frame is a little time consuming, but well worth the effort.
