Derailluer cable is standard. If it looks like this, you are good.

There is no trick to seating the cable. As long as shifter was set properly, it should slide in easily once you pull cable through. You need also to make sure the cable routes to the derailluer properly and that all the housing is seating into the various stops securely. Then pull the cable taught and attach to the pich bolt onthe derailleur.
That looks like what I have.
And that is pretty much what I have done but it is still not working.
Just can't figure this one out.
