Well, if you downloaded the right one, you should see a this item on the first page of the introduction under "CROSSFIRE VIN CODE BREAKDOWN" -> "N = 3.2L V6 Supercharged".

If you don't see that, then you probably downloaded the wrong one. The file size is just slightly smaller than for the 2004 service manual.

The link in the first post of this thread should have had you download "2005_Crossfire_SRT6_Service_Manual.pdf"

Let me know if I am incorrect.
