whre is pcm located?

I have a 93 Bravada. Where in the h*ll is the pcm? It"t not behihind kick panel or glove box. Can't find the darn thing!

On a '92, it's standing behind the glove box w/ 2 multiwire connectors plugged into the bottom.

nope heater core is there

FOUND IT had to stand on my head but was tucked in front of core! YOO! HOOO!
