Tagging a Family with Multiple Connectors in Revit MEP

Heads-up from Ideate Solutions, originally from Revit Clinic:
tagging the physical wires instead of tagging the device:

1. draw wires coming off of each connector as small as possible 
2. (if the wire is short enough, the arrow head will not show up.) You can then 
3. hide the dot/short line of the wire in the symbology of the family and 
4. tag it.
