DIY ECU editor interface question

Bearded

Hello all,
I’ve just completed a rebuild due to a melted piston on a new to me bike. It had an old PC3R that I can’t connect to so I’ve decided to go the route of ecu editor since with the pc3 I have spots that are way to lean. I have built the soy interface based off of a diagram I found posted. My question is the diagram shows the pin for the tech line coming from the ecu (to cluster) but is doesn’t show where it needs to be connected to. And I’m assuming I need that to be connected somewhere to be able to use the monitor engine in ecu editor. I know the boost by smith interface has a connection to that pin also. If anyone know where it need connected to that’d be much appreciated thanks
