Where is EGR on 93 LS

[[iV]Kermit]

I'm having trouble locating the EGR valve on my 93 Trooper LS. I was told it may be clogged and is really easy to clean.

I surfed around to look for pictures but the websites seemed to have been closed.

Brief description and schematic of EGR:

PURPOSE
Allows a metered amount of exhaust to recycle in to the intake stream.

LOCATION
On the common chamber.

OPERATION
This valve is controlled by a flexible diaphragm which is spring loaded to hold the valve closed. Vacuum applied to the top side of the diaphragm overcomes spring pressure and opens the valve in the exhaust port, allowing exhaust gas into the intake manifold and thus to the cylinders.
