For your 2020 T3500 Transit Cutaway Chassis, the Tekonsha # 22114 you'd looked at would be your best bet. Because your cutaway chassis isn't likely to have the factory taillight assemblies as would be found on the van model, you'll need to cut off the plugs on the harness that are intended to tap into the factory taillights and hardwire those into the existing taillight wiring harness. The green wire carries the right turn/stop lamp, the yellow wire carries left turn/stop lamp, the brown wire carries the running lamp circuit and the white wire is the ground. I've linked to an installation video which will walk you through the installation process (with the exception of connecting at the taillights).
