Is there one in the Soloy Conversion? ... I'm guessing you're referring to the EOS test switch. From what I remember, yes, the Soloy conversion does have one if you get the 700 series engine (aka gold package?). If I remember correctly it was a safety covered toggle switch mounted right where the panel and centre consol meet, so right near your left knee. What don't you like about it? Where was it mounted for yours?
