Ozzy P. United StatesAwesome company.
This harness was super easy to install. The customer service is also spot on. I had a few questions and either I found the info on their YouTube channel or they got back super quick. Looking forward to doing more business.

Have not installed yet. But videos seem to make it look like it's going to be straight forward and not an issue. Product quality is spot on!

Roger W. United StatesGreat solution!
After being put off by my dealership, I decided to try installing the Boost harness. The installation video was good although my specific install differed slightly. A quick call to Boost's tech support filled in the gaps. The harnesses work as designed. Total installation time for me was about 5 hours.
