You will need towbar baseplates permanently mounted on the car, which requires temporary removal of the bumper and front end panel. Blue Ox is a popular brand, as is Roadmaster— primarily because their baseplates are custom-fitted and require the fewest modifications to the vehicle.
You will need a towbar to match the baseplates. You can mix brands with the right adapters, but it's just as easy— and no more expensive— to use the same brand for baseplates and towbar to avoid the need for adapters. So choose the baseplates first, then choose the towbar.
You will need supplementary lighting (tail/turn/stop). Which doesn't require a wiring harness from Ford because they don't make one for this application, but does require a wiring harness custom-made to go from a newly-installed connector on the front end of the toad to the lights at the rear.
You will need supplemental brakes. Legally
you only need the brakes if the toad's GVWR is higher than the gross trailer weight that requires brakes in your domicile state (3000# in many states, 1500# in some states). However, even for a lightweight toad, expecting your Interstate's brakes to stop both vehicles without assistance from the toad brakes is asking for trouble. Side note, if you only have one toad and you're going to have it for a long time, consider permanently-installed supplemental brakes with a control box that mounts under the driver's seat. If you have multiple toads and/or you plan to trade in your toad in just a couple of years, portable supplemental brakes may be better because they can be transferred between vehicles and you only need to buy one, but then you have the hassle of installing the control box in the driver's footwell every time you tow and removing it every time you drive.
You may or may not need a brake controller installed in the Interstate. Depends on the brand and type of toad brakes you install. My Roadmaster Invisibrake activates when the van's brake lights come on, and no separate brake controller is required.
