Trailer Wiring Recommendation fro 2010 Toyota RAV4


I have a 2010 Toyota RAV4 with the factory towing package that includes some wiring for a trailer. Is there a different wiring harness for the factory towing wiring harness?


Expert Reply:

Does the wiring you found look like the attached picture? If so, you could use the part # HM40975 to give you a 4-way and a 7-way.

Otherwise what you found may not be trailer wiring and instead you'd want the # 118412 which I attached an install video for.
