Yes . Some it's as easy as rearranging the stock plug connections in the harness .Are the new 40" mes able to be pid upgraded?
Think of it as you're buying the insulated cabinet . Bypass the guts and hook up the controller .I would get a recent generation but I don't trust their reliability.
I'm heading to Buffalo tomorrow. I'd love to find one there. Only 80 miles north....I have been looking for one on Craig's List. Looking under the location of Pittsburgh (where I live) and keep getting results from Seattle, York, England, Buffalo, etc. Apparently people in my area don't want to part with them. I would get a recent generation but I don't trust their reliability.
