Location of ECM on an ISC350

Hi Folks. Some may recall I had a check engine light in the fall that I traced to a bad ground. While looking for this I had suggestions from some on also checking the ECU. The thing is I never actually found the ECM and I would like to know for future reference as I think the problem may still be intermittent. I wonder if someone could chime in on where it is and more specifically if you could give me a reference when looking straight down on the motor facing the back of the coach. It is a 2003 ISC-350 Caps motor.

Thanks in advance.
