Where is engine ECU so I can find extra wires near it

I need to know where the engine ECU is.  More specifically I need to know where the extra wires are that according to the owners manual come out near it?  I have looked all over the engine compartment and can find nothing that looks like the ecu that is on a car.  Do they look different or is it not in the engine compartment.  Does any one know where the extra wires labeled  38198 EX1 through EX5 come out at?

The ecm for your Cummins ISL engine should be on the passenger side of the engine. Silver colored box with two large wire connectors. May have to contact  FOT or Cummins for a pinout  of the wires.

This will help identify components.  It's not the pin out diagram.

The extra wires on our 99' U270 come out on the street side near the hydraulic pump reservoir, near where the wires for the towing set up meet up with transverse frame that the hitch is attached to. Your coach may be different... When I found ours, the extra wires were coiled up in the black plastic split loom with the open end taped up and tucked into the open end of the large rectangular framing that supports the engine mounts.

Never did find the extra wires next to ECU or the ECU for that matter.  Ended up using the extra wires that go to the rear of the coach (bundle 2088).  Used wire to run from switch in coach to a relay to turn HWH compressor on and off.  Now I don't have to pull fuse to turn off compressor. Thanks for everyone's help.
