We recently upgraded our toad to a 2021 Jeep Grand Cherokee. I had the RV dealership rig up the new toad for towing, including adding supplemental brake system for air brakes. I was informed today that the toad is ready but that i had to take the toad to a Jeep dealership to have them add a “flat tow harness for the power steering”. I’ve tried finding information on this part, I assume it is a wiring harness. Does anyone have experience with this issue?
