When installing the # ETBC7 you will use the 40amp breaker to go between the battery and the 7 way on the 12v hot lead; the 20amp or 30 amp breaker will be used between the battery and the brake controller along the power wire for that. Which breaker you'll use will depend on which brake controller you're using, so you'll want to check the instructions for the brake controller you're using to determine which one should be installed.

I've linked the installation video of the ETBC7 on a similar Toyota Sienna, as well as one of our helpful articles on installing a 7 way that you can use as a reference for this process, too.
