G-tec in Detroit Mi. I think can install. Also a company called On-Spot has dealers in Indianapolis In. Check web sights for both companys. I'm sure they can direct you in the right direction. By the way I've used the automatic chain up system and boy is it slick. Good luck and keep us posted how you make out. I had my system installed in Lansing Mi. at Auto Truck Service, unfortunately they closed there doors last month.
