Works w/ 2018 STI 2 months ago
5out of 5stars

This is a great harness I used in my 2015 and now 2018 STI. The plug is now on the horn below the passenger headlight so it does take some re-routing of factory connections, but the plug fits and I was able to hide all wires for a clean install.

Makes installing the Hellas a breeze One thing I will say is the plug in to the stock harness is just not QUITE right. It doesn’t hold/fit right and you pretty much have to use the supplied shrink wrap to hold the plug together. Otherwise awesome product!
