Jason, I picked up a remote from talladium all ready to rock, vaniman also has them. Our new ez mill is fully automated on the vacuum end and its like the Roland on and off. In fact I have an extra fitting for the mill side but don't have the relay box but I also have a com port side if you vacuum has that type if connection on it, pins 1 and 4 are the only two use the top outer wide pins when you are looking at the plug. Let me know. I can mail them to you.
