Hi George,The call to Searchfeed is in (assuming you're using your default skin) skins/default-results.html, line 27 I think.
You can replace the SF javascript line with Adsense javascript.
But, if you want to include both on different pages, then you need to create another skin to contain Adsense instead of Searchfeed.
To switch back and forth, on your pages, use &skin=default to display SF, &skin=newskinname to display Adsense in your SSI tags.

p.s. - I suggest making a backup of everything you change. Skins can be tricky if you're not used to them.
