I installed the carb heat, throttle, mixture and prop controls. Basically, I used the Vans Aircraft RV-10 control kit, but the throttle cable was too short (47.5 inches). I ordered a 52 inch replacement from Aircraft Spruce, who in turn ordered it from ACS, which for about $180, including 2nd day shipping and a $50 expedite fee, had it delivered two weeks later. The cowl flap control had previously been installed.
