How To Hook Up Reverse Light Circuit On 2021 Toyota Sienna To 7-way Connector ETBC7L

Question:

Hi, I hooked up the 4-way connector and was wanting to get the reverse circuit hooked up as well. Do you have any documentation or wiring diagrams to achieve this? Thank you

I would be happy to help!

The 4-way connector # TK69FR you purchased for your 2021 Toyota Sienna cannot have a reverse light circuit, as it does not have enough circuits in the connector for a 5th function.

Instead the # ETBC7L 7-way connector you purchased is what will have the reverse light circuit. You will just need to hook up the yellow wire on the back of the 7-way to your reverse light circuit. Using the circuit tester included with the # ETBC7L will help you find the correct reverse light wire.

I included videos of the products mentioned for you to take a look at.
