Where are the iMac Intel 27" EMC2390 Diagnostics LEDs located?

I know I need to check the diagnostic LEDs in order to troubleshoot a number of issues, but I can't seem to find them. I have the iMac then down with the display removed. Can someone please tell me where to look?

Never mind, found the answer here on pg 29...

"Diagnostic LEDs

The iMac (27-inch, Mid 2010) computer has four built-in diagnostic LEDs on the main logic board that can help you to troubleshoot the computer. The LEDs are located on the bottom left edge of the logic board (under a piece of black mylar tape) and can only be seen when looking through the lower vents of the enclosure. Refer to the next page for a close up graphic of the troubleshooting LEDs.
