I just picked up a 2015 Western Star 4900ex with a DD16. I would love for it to have the DataStar, does anyone know if this is a upfit that is a relatively easily achievable project? If I had to guess there's a wiring harness already behind the dash somewhere and hopefully it's just a plug and play type of install.
