On my 2006 Coachmen Aurora I have a switch just to the left of the living room slide switch that is marked for manual over ride. If you push it on the top it is for the kitchen, pushing the override switch on the bottom is for the Living room.(I could have the override Kitchen and Living room backwards) My slides are electric. I have a switch to the far right that control the bedroom slide with the manual override just to the left of the bed switch. Hope this helps you
Added information In my wheel wells are the manual crank shafts. Someone need to hold the switch then ratchet the slide in.
