Welcome to the AT forums.
The front panel header pinout is on pg. 24 of the manual I just downloaded. If you don't find a 4-pin header connector coming from the front panel, then maybe they include one of those little black things in the parts box on two wire legs connected to a 4-pin header connector. I can't imagine that as expensive a case as the TJ09 wouldn't include something, but then I've seen lots of examples of "cheap barstidry" from mfrs lately... :roll/;
