DC Input ES7 Kawai

Does any one know where I can get a dC input board mount for a Kawai ES7?
What would you call this

Do you mean the DC input jack, something like this?

This one works with the ES-4, and I am checking with Kawai to see if it is the same part for the ES-7.

Yes, the part #3486 works for the ES-7 as well.
