Hello: I have had my 86 300E now for almost 3 months. When I got it, the air cleaner hose was gone. I finally got a new one to go on, but I noticed there is a place for a sensor to go. I have looked high and low, but I do not see anything on my car that was laying around just waiting to be plugged into the hole. Is there a sensor, or is the new hose kind of a fit-all that would go on several models?
