Going from this old controller that's wore out to a newer upper controller but having some tubing issues and cannot find the answer any where after 3 days of searching online and at my local businesses. Any help to identify what the 3 ports are for and of the 3 which one would I plumb the 1/4" tubing into. Which one needs to be blocked off.
