Themes not from wpmuDev What Code is needed

I know I have asked this about 10 Months ago and I did a search for the subject But for the life of me I can’t find it.

I want to use themes from Elegant Themes to be used for my Premium Themes.

I know they should work fine but with plug ins like supporter ads and Ad Sharing or any other plug in wpmudev offers what codes would I need to ad and Where Would the Code go?

Sorry if this was discussed, I could not find it.
