Engine Electronics

[JDalton]

As I looked over a 2500 CTD on the dealer lot (trying to make the final decision) I noticed that it appears the engine electronics are mounted just under the fuel rail/filter side of the engine. There appears to be numerous electrical connectors in this area. If this is the ECM it seems to be mounted in a rather hostile area with exposure to heat and moisture. Is this a problem area or are the connectors and electronics sealed sufficiently to protect them. Is there any known problems with this setup. I assume Cummins sells Dodge a complete package that is a drop in power unit so maybe this is best since it is done correctly from Cummins without any third party tampering. Assuming this is the ECM. Thanks in advance for any comments.

Looking at the one in my driveway I believe that is the ECM. It appears to be sealed well. I still wonder about heat though were it is mounted.

Yes it is the ECM and their just about bullet proof.

All Cummins equipped big rig engines are built this way and have been for years now. Luckily that computer is built by Cummins, not dodge.

The EMC is on the divers side of the truck. It is on the side of the block toward the front of the motor mounted down low. Its a big silver box with 2 large multi pin connectors hooked to it.

Thanks for the replies. Sounds like the location of the ECM is not a problem. One more positive bit of info I need to make up my mind as to what to buy. The Cummins looks better all the time.
