Expert Reply:

If you've already got a 4 way on your 2013 Toyota Sienna you can use the # C57674, but that doesn't come with any of the additional wiring, circuit breakers or butt connectors that you'll need to make the connection. You would need 40 amp # PK54540 and 30 amp # PK54-130 circuit breakers, 10 gauge 2 wire jacketed wiring # 10-2-1 and butt connectors like the # DW05745-10.

With that said, the # ETBC7 kit gives you everything you need and is likely going to be a more cost effective solution to adding the 7 way connector on your 2013 Toyota Sienna. Once you've installed your 7 way, you will be able to use the Curt Spectrum # C51170 and adapter plug # C51515.
