Trailer Hitch Wiring

[bldunne]

Has anyone found the electrical parts needed for the wiring to hook up a Class I trailer for a 2007 Yaris Hatchback? I have a flat four prong trailer wire system. I think it has to be wired directly to the battery. The trailer just has standard tail and marker lights.

Any help would be cool. :thumbup:
