Question about Sea Foam Cleaning ASAP!

[Crysis]

I was told to use Sea Foam to clean out my engine, but I dont exactly know what to pour it in. A memeber said to pour about a third of it into the big vacuum line on the back of the intake duct, but there seems to be alot of vacuum lines. Also, he said to pour a third into the vacuum line thats hooked to the end of the driver sides of the intake duct, and again Im not sure which one this is. I am new to working on cars so i dont want to pour it into the wrong line. Any help? Pictures please.
P.S. respond as quickly ASAP because I have my hood popped in my driveway as we speak Thanks
