Fill to the bottom of the "fill hole". When the fluid starts to drip out of the hole that you are filling in the diff, then you are full.
If there is not a drain plug on the bottom of the differential then you will have to remove the rear cover. If that is the case you will need a cover gasket. If it is limited slip, then it will require a special additive. Also be sure of the weight and if it is synthetic or not.
