Rangerred-
Here's a link to a wiring diagram for a 2005 Kountry Star:

I dunno... When i look at sheet 92 of that diagram set it seems to me the place to start is to make sure the STOP PRESS SW is putting out 12V when you press the brake pedal. That switch's output goes to the TURN SIGNAL SWITCH, the STOP LT relay, and the SERVICE BRAKE STATUS relay, and is the only common element that I see that feeds both the CHMSL and the brake lights at the rear of the coach.
I could be incorrect, though!
NOTE: One place you can check the STOP PRESS SW is at the TOW VEHICLE connector, pin 5. That connector is the one that is used for an electric brake controller. It should be under the dash.
