Will Hopkins HM43534 Work On 2021 Nissan Frontier With Factory Tow Package?
Updated 10/27/2025 | Published 03/04/2025
Question:
I have a 2021 Nissan Frontier with the factory tow package installed. I have used it multiple times with no problem. I am wanting to upgrade to the HM43534 listed. I just need to make sure that this will power my Curt Echo Wireless brake controller like my factory 7 blade did. I have provided a picture of the trailer plug that I am replacing. Thank you.

Hello Jason, thanks for the picture! Sounds like you are on the right track here, because the Hopkins # HM43534 is exactly correct for replacing the plug in your picture. Since your Frontier has the tow package, you will be able to simply plug in, mount the socket with the included bracket and you will be good to go. It will work great with the Curt Echo wireless controller.
