If you have no power to the trailer wiring harness, the fuse panel is located in the engine compartment. I have attached a drawing that shows where the fuse panels are located on a 2006 Highlander.

Per the second attached drawing the fuse for trailer lights is number 11.

You will want to make sure you check the connector and the wires for the trailer connector for signs of damage. A short may have been what blew the fuse.

If you need a replacement trailer connector I recommend part # 118248. This plugs right into the OEM port on your Highlander. This is for your Highlander if it HAS a tow package.

If you do not have the tow package I recommend part # 118413.

When working with electrical connectors I recommend using dielectric grease like part # 11755. This keeps dirt and moisture out of the electrical connections and helps prevent corrosion.
