    Worked as a replacement for the old one on our camp trailer
  

*by J***. on Reviewed in the United States on June 16, 2023*

This worked great as a replacement to the old one on our camp trailer.  Nice that it had a cover, hopefully that will help with being able to remove the wires if needed down the road.  The old one was working but it came apart when I tried to removed the wires.
