How to Add 5-Way Wiring Connector to a 2024 Toyota Grand Highlander With Factory 4-Way Connector

Question:

I have a 2024 toyota grand highlander with a factory installed tow package which includes a 4 pin connection. My boat trailer has a 5 pin connector. what adapter is available to connect the vehicle 4 pin to the boat trailer 5 pin so that all the trailer lights function correctly? If there is one, is it difficult to install?

Hey Mark, thanks for reaching out!

In order to get your 2024 Toyota Grand Highlander to function with the 5-Way on your trailer you'll need to install the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036. This plugs into your current 4-Way and you splice it into your brake light function. This comes with a quick-splice connector so once you find the right wire on your Grand Highlander it's a simple matter of clamping it around that wire and the blue individual wire and you'll be good to go!
