I'll have to assume your looking for the engine ECM

Both Cummins and Caterpillar mount their ECM on the intake manifold side of the engine . In a diesel pusher , that's the passenger side.

If you require more info ; please add your engine size ( ISB ? C-7 ?) and chassis manufacturer to your post .
