The WFCO or other converter is usually near the fuse panel if not right behind it. In our Cougar, you have to remove a wooden panel at the bottom of a cabinet to get at the WFCO while the fuse panel is at the top of the same cabinet near the ceiling. The main control panel with tank gauges, slide controls, some lighting controls is in the same cabinet.
Everybody's Keystones seem to be a bit different but they still have a lot of similarities. If you know where the fuse panel is located, listen for a very faint hum nearby when the trailer is plugged into shore power. The very faint hum will likely be the transformer in the converter. A louder hum is more likely to be the cooling fan on the converter.
