ECU Location?

Sorry for the dumb question. I finally got a new ecu and I went last night to change it. I always guessed the ECU's were in the floorboard of the passenger seat. I removed the rug, then a black cover and all I see is more black covers. Can someone tell me tell me where it's located?

Thanks,
-d

I'll be interested in this as well. I'm considering a 'Speed Innovations' upgrade this winter...

Many mfg's put them in the engine compartment; However, there's probably a TCU (Tranny Unit) tied to it ?

Thanks,
Robert
