    I have the 2018 base model Mustang with the 4″ screen. I already had the Screen, bezel and the Sync3 module in hand but I needed the conversion kit. I reached out to Sam and helped me through the order. With his help, I ended up getting the Harness kit/USB hub- cables and the programming files (provided by him) which completes the full kit and ready to install. The install was very easy, simple and the most important thing is the kit that Sam provided worked perfectly fine. Thank you for all your help !!!
