Expert Reply:

I have an option for you, but there is not a custom fit trailer wiring harness for your 2021 Chevrolet Bolt EV at this time.

With that said that does not mean you cannot install one.

I recommend using the Upgraded Modulite Vehicle Wiring Harness Kit w/ 4-Pole Trailer Connector and Installation Kit # 119147KIT as it comes with a circuit tester to find the correct wires on your factory harness to connect to, and since it draws power directly from the battery of your Bolt EV to protect the factory wiring from damage.

I included a video of the # 119147KIT for you to take a look at.
