I have a 2012 F150XLT extended cab 8CYL. The cruse control will not engage. I replaced the steering wheel switch and I replaced the disconnect/break light switch at the foot peddle. It still will not engage. Apparently there is a third redundant switch under the hood in older models, but I can't locate it in my model. Would my year have this third redundant switch? As well, is this the next best course of action? I don't want to get a speeding ticket! LOL!
