I finally got my 2017 Highlander Hybrid ready for towing our '06 Scamp 16. We sold or '08 Hi Hy and so had to start all over. The after market hitch was straight forward bolt on and the 4 prong connector was pretty much plug 'n' play. It's the other three connections that presented more of a challenge. The 12 volt battery is in the rear, the brake pedal switch has four wires to control the regenerative braking, the back up lights are in the tailgate, and the car's computer is fussy about anything being messed with. This afternoon, I took it out to adjust the brake controller and everything worked perfectly. It even looked like I may be able to use the fridge on 12 volts while traveling. Yay!
