Can’t really help you but on my SOB it’s on the ceiling of the electric compartment towards the back. It cannot be accessed unless you are kneeling and leaning mostly into the compartment! I have NO idea why they thought this was a good idea but there it is. I likely would not have found it but for the PDI. On my last coach it was on the outside about waist high mid-coach. Right where a logical person would put it. Go figure.
