Hi all. I just bought my 2022 wagoner, series 2. It is equipped with the heavy duty hitch and 7 pin and 4 pin electrical connections. However, it did not come with the integrated brake controller. I am looking to install my old Tekonsha controller I took off my last vehicle, but I am having trouble finding the right harness to connect the car to the controller. Anybody have any input? Thanks in advance.
