I have the same KMS TrueTrac diff (not a fun swap into my CSX by the way even though it is a direct replacement). There are two breather options, depending on how you are set up. One is an AN fitting on top of the diff toward the driveshaft. KMS runs a line to a catch can in the trunk. The other is a fitting toward the top of the diff cover. Make sure one is capped and the other runs to a catch can.
