Ecu Fcc Id?

I've read that every ECU has an FCC ID (not unique) and its supposed to be on the ECU. I pulled the ECU out of my 2002 Tundra today and didn't see anything resembling an FCC ID. I even opened the ECU to see if it was labeled somewhere inside. Nothing inside, there was a label on the outside with some numbers, but it didn't look like any of them were the FCC ID. Did I look in the wrong place, is it somewhere else?

Thanks in advance!

Well, got all the info I needed, and more, from TundraSolutions... good message board.
