Replaced AC compressor. Can't find fuse/breaker.

On a Freightliner Custom Chassis used in a 2015 Holiday Rambler Ambassador, the A/C compressor and dash HVAC fuses are typically split between the Front Run Box (the exterior electrical compartment on the driver's side front) or an inline fuse holder near the rear battery/relay compartment, depending on how Holiday Rambler integrated the Evans/Tempcon dash air system. [1, 2, 3]
Front Run Box (Exterior Driver's Side)

• Location: Look in the outside storage compartment/cubby directly below the driver’s station or forward of the front-left wheel.
• Access: Remove the protective plastic or black cover (usually fastened by thumb nuts or quick-release clips).
• Details: The backside of this cover or the panel label map typically details chassis fuses, which cover the dash ignition, blower feeds, and primary control power. [1, 4]

Rear Battery / Relay Compartment

• Location: Check the rear compartment where the house/chassis batteries and heavy-duty solenoids are housed.
• Details: Motorhome builders often place an unlabelled or separate inline fuse holder (often 10A to 20A) or a small auxiliary panel right next to the clutch relay for the engine-driven A/C compressor. [2]

If you can see power at the dash switch or need help tracking down a refrigerant pressure switch that might be cutting power to the compressor clutch, let me know!
