I can almost get a decent pinch harmonic but any ideas on how to get them properly other than just practice?. A good video tutorial link would be good.

I have my own way of doing them. As you pick, pluck the same string with your ring finger at the same time as you're hitting the string.

It works.
I suggest learning how to do a pinch harmonic the mainstream way because they are fast and (eventually) extremely easy but if you can pull it off fast with your ring finger than do it.
