We do have a 7-Way wiring connector that you can add to your 2014 Toyota Sienna so you can tow your pop up camper! You do need to already have a 4-Way though. If you don't have a 4-Way connector then I recommend going with the Tekonsha T-One # 118498 because of how reliable it is. This tees in behind your tail lights and draws power directly from your battery via the black power wire. Attached is an installation video.

Then if you only need the lighting functions I recommend installing the Curt Adapter # C57674 which gives you both a 7-Way and a 4-Way for any towing application that calls for lights. If you are wanting a fully functional 7-Way I recommend the Universal Wiring Kit # ETBC7 instead as it comes with all of the wiring and connectors needed to add the 12V power and brake controller wires for a traditional brake controller like the Prodigy P3 # 90195.

If you don't already have a brake controller though I highly recommend installing the Wiring Kit # ETBC7L so that you can use the Curt Echo # C51180. The Echo only requires 12V power on the 7-Way to function. It automatically adjusts the braking power of your trailer to match that of your Sienna but you can also adjust this using the mobile app. The Echo can connect to an Apple or Android device (8.0 or newer or 4.4 and newer OS requirements respectively) via Bluetooth so that you don't have an extra piece of equipment mounted in your vehicle.

Installation and review videos have been linked as well as some written instructions for you to check out.
