Question:
When comparing 2 harnesses for 2020 toyota highlander, the Curt C55245 and t-one TK74FR, it looks like they are wired differently. It appears that the ground and running lights along with the left and right signal are opposite when comparing the vehicle connectors of the two harnesses. Can you confirm if they are the same? If they are different how do I know which one I need? Thank you for your time and assistance.

Hey Todd, I can assure you that the Tekonsha part # TK74FR and the Curt # C55245 that both are a confirmed fit for your 2020 Toyota Highlander are wired the same and would work identically. If it were me I would go with the Tekonsa just because it's currently priced better but also in general we have the best luck with the Tekonsha harnesses.
