### ⭐⭐ 







  
  
    Not a direct replacement for Montero Sport
  

*by R***H on Reviewed in the United States on February 26, 2020*

Not a direct replacement for 2003 Mitsubishi Montero Sport. The plug has to be modified for it to connect to the plug.

Got this for my 2003 Mitsubishi Montero. It went bad after 4 months of regular use. Will be contacting the company for a refund.
