Where is the ECM?

Can some one tell me which box is the ECM?
I assume the PCM is the 3 plug box on the fire wall?
I'm getting a P0606 ECM code. Which box is that?
Thanks in advance.

ECM is located on the driverside and bolteddirectly on the engine, about the middle. You will see a very large 50pin/100pin??? plug going into it.

Guys
Can I temporarily install an ECM off an identical truck as a test? I know the VIN will not be correct but I don't want to end up with two dead trucks. I'm getting codes along with 0606 that talk about low input voltage at temp sender, turbo inlet temp and apps. The truck started running very bad, the temp gage went crazy and the throttle pedal was acting up. Also the cruse control indicator cuts on and off. People on other threads with similar symptoms ended up replacing the ECM. The other problem I'm having is that not many builders, like ACE, are still doing them. Smarty says they can set up their unit to flash a used box off another truck which might give me an excuse to buy one. Any input is appreciated.
Thanks
Jeff
