Google Play/ Android on Fire HD 6

I've seen tutorials and things for installing cyanogen or google play on the Fire HD 7. What about the HD 6? My device is rooted with kingroot. Only problem is that trying to install google play does not work. I can search for things but I cannot install anything. It give me a communication error. I need help figuring out how to install google play properly and how to get it to work. Either that or how to install cyanogen onto my device. Again, this is a kindle fire hd 6 that I am working with. Please help :(
