I found an LED brake light in the auto section of Walmart. Then I ran a pair of wires to the hot side of one of the rear brake lights and ground.

I ran four wires into the topper. Ground, brake light, 12 volt straight from the battery, and 12 volt switched (on when the ignition is on). I put a four prong SAE connector in the box so I can unplug the topper if I ever take it off. The SAE connector is the flat connector used to connect trailer wiring. Any auto supply store has them.
06 Canyon: The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.

22 Maverick: Summer 2022 burned 62.74 gallons in 3145.1 miles for 50.1 MPG.
