Exactly the right part!
My trailer lights stopped working. I talked to several people who gave me diverse advice. Went online and found this part to replace the trailer wiring on my 9-year-old Highlander. The pictures showing how to install were excellent and the installation instructions clear. I had never done anything like this before and was pleased that the "20-minute installation" only took me 80 minutes! Worked on first try!
