You will want to use a powered type 4-pole wiring harness in your Yaris to help protect the car's wiring from any potential damage from faults or shorts in the trailer wiring. I suggest the powered harness kit # C59236 from Curt. This kind of harness avoids drawing current for the trailer lights through the car's own wiring, and instead delivers it from the battery via the included black wire.
