Default Removing the ECU?

Anyone know where that thing is in a 1994 LS? I removed the panel below the glovebox, and theres a lot of wires and plugs in there, plus that airbox where the airfilter is, but I cant find the ecu. Anyone have a picture to point out exactly where that thing is hidden?

Well in mine the connections are on the bottom, so if you just need to disconnect the ECU you only need to remove one panel that is held by clips, but in order to actually remove the ECU I had to disassemble half of the dash, lol.
