Hi Doing it myself,
Thank you for your question! With a 3-Setting Diverter Trim, only the top and left port can be used. If you wish to connect three shower components, please purchase the 6-Setting version of the trim kit (T24967).
The shower heads and sprays can be connected to any of the 3 ports with a 6-Setting diverter. However, we recommend connecting the shower head to the top port.
Please refer to page 7 of the instructions for reference as to which ports will run at each setting.
