coolant flush question

[YellwMonky]

Time to flush the coolant! I went to Kragen and bought the Prestone Flush and Fill Kit (http://www.partsamerica.com/PartDetails.asp?SourceArea=&SourcePage=SEARCHRESULTS&MfrCode=PST&MfrPartNumber=AFKIT&CategoryCode=3051). reading the installation instructions, it says there are two heater hoses the come from the firewall. one leading to the water pump and the other leading to the "top of the engine." I'm having trouble finding which one is which. I'm supposed to install a "tee" into the hose leading to the "top of the engine." Could someone help me out? I will include a picture of my engine bay. I'm thinking the hose with the two clamps..? Or am i wrong?
