    Almost perfect fit, one or two a bit shorter than originals
  

*by T***N on Reviewed in the United States 🇺🇸 on May 16, 2022*

Excellent quality and worked perfectly fine, but one or two wires just a tad bit shorter than the originals.  Was still able to get them installed without any drama, however, and they all work.
