I have a 02 Toyota Sequoia with a 4 way flat connector, and my trailer has a 7 way. Can you recommend the best way to install a 7 way conversion on the Sequoia? Thanks

Hi John; since you already have a 4-way on your vehicle the only thing you need is the Universal Installation Kit for Trailer Brake Controller # ETBC7. This kit comes with the adapter, wiring, breakers, and everything else required to upgrade your 4-way to a 7-way.

Hey John, how did the upgrade to the 7-way connector on your Sequoia go with the ETBC7 kit? Your update could make it easier for the next person working on the same wiring setup.
