My research lab has a GC 5890 has connected with an external detector of PDHID; and I know the GC can be used for FID & TCD if I can connect back to the gas lines correctly. However, I don't know how I can do that especially for TCD. I would like to find some pictures/schematic for the line connection, but I can't find any specific ones (the internet information is more likely for demonstration or sales picture). Can some one help me with the setup connection (see the link for the pic)?

Thank you very much!
