I don't have a picture, but you will have to take the rear skid plate off to see it, on the X1100C there are 5 bolts holding skid plate on, when you see the bell housing after skid plate removal you'll see the plug at the bottom. Earlier in the thread there was a suggestion of using a hole drill so the plug could be access without removing the skid plate, I didn't do that so I will be laying under the RTV one more time.
