What controls door lock and dash lights?

[PaulJohnson]

Have a 05 2500 that was flooded and trying to find out what controls the interior lights and functions. I know chevrolet has a BCM (body control module). What does Dodge call this? Where is it located?

CCN (cabin compartment Node)... ... ... . instrument cluster acts as the body controller

Ok, it has been awhile since I have posted anything about my flooded truck. I have since replaced the fuse box under the hood, the FCM ( the small metal box that plugs into the fusebox under the hood), the wiring harness from the fuse box to the main plug under the dash. I picked all these parts up from ebay off a 2005 Dodge 2500 for $65 bucks! I still have no dash lights, no power windows, no power seats, no radio, nothing that pertains to the dash or creature comforts. What does work now is the over head read out, it will now turn the engine over. Any suggestions of parts to look at or replace? Also, does the ECM tell the dash cluster the mileage or is it stored in the cluster itself?
