Recommended 7 Way To 4 Flat Adapter For A Tesla Model Y With Factory Tow Package  

Question:

I have a Tesla Model Y with factory tow package. I need a 4 pin to 7 pin adapter for my bike rack led tail lights. Which adapter will work? Pollak 7 Pole to 4 Way Connector Adapter Item # PK12716

Expert Reply:

It sounds like you are already on the right track. You can indeed use an adapter like the Pollak # PK12716 for this purpose. This will plug in to the 7 way plug on your Tesla Model Y, and give you a 4 flat connector on the other end, which you can plug your bike rack into.

We made a brief install/review video which I have linked below.

Hi Can I use this to power brake lights and turn signals on a Thule Archos cargo box? I am also using a 2025 model Y with a 7 pin adapter. The Archos is a 4pin adapter.
