Yeah it's not going to convert the separate trailer wiring circuits without some type of converter.
If by chance your tractor has separate taillight wiring, meaning that the turn signals and brake lights run on separate pins, you will need to add a converter, like the Curt # C56175. Just cut off the 4 way end and wire it into this adapter. I have attached a picture which illustrates this.
In order to determine if your tractor has separate or combined wiring, I recommend using a circuit tester like # PTW2993, to test the functions of each pin. When doing so you will also want to make sure that the connector on the tractor and the adapter are pinned alike. I have attached a picture for this as well.
