This is Scott from Ajax. I believe we spoke the other day? (your from the mid-atlantic region?)
I should have mentioned this when we spoke but, if you would like, I can supply several references in your area for you to talk to. Some of them have done 5-10 Boss retrofits with our control and they are generally quite happy to provide pointers and advice regarding their own retrofit experience(s)
If you don't get the answers you are looking for here, please feel free to give me a call.
