• If your old pump is model# SP-160X01T (ends with T) then you can order this pump without needing a plug adapter.
  
  
• Examples of solar panel model numbers that have the new threaded-style plug:
  SF0W6ST, SB1W1ST, SB1W5ST, SB1W5DT, SB2W0DT
  If your solar panel is one of these numbers then no you do not need a plug adapter.

• If your old pump is model# SP-160X01 (does not end with T) then you have a an older version which has a discontinued plug style. When you order new pump model# SP-160X01T you will also need to order a plug adapter which is part# PA-10 to be able to connect it to your solar panel which would have an older version of the plug. The plug adapter goes in between the plugs and lets you connect a new pump with a threaded style plug to an old panel with a push together style plug.
  
  
• Examples of solar panel model numbers that have the discontinued push-together style plug:
  SF0W6S, SB1W1S, SB1W5S, SB1W5D, SB2W0D
  If your solar panel is one of these numbers then yes you will need a plug adapter PA-10 to be able to connect this new pump.
  
  
• If you already have a plug adapter from a previous order then you can order just the pump.
