Thanks roverp480 for your reply, may be i should have explained myself in more precise terms. as i have this unit out as i said, there seems to be a part missing from the bottom where the wire is connected. the (p3 parts book only shows the unit P/NO 09068) from the inside view of the part of the unit and not the outside view. would any one have a photo of the outside view. this would be greatly appreciated thanking you in anticipation best regards Derrick.Smith
