Where to Install Pro Power Kit?

Hi, i’m trying since 5 hours to Install my Doorbell Pro. I’ve read a lot of helps, manuals, called the service but I can’t find a solution. My Internal Doorbell has No Front, Trans and Rear but it looks like in the manual.
My Doorbell ist working with this Installation

My installation ist in Attachment.
Is my installation right? Where I have time put the PRO POWER KIT?

Hey @Animus ! Can you pleae provide the make/model of your Chime Kit?

Do you mean Ring Chime Kit?

Hey @Animus. Chiming in for Jennifer here! We are needing a picture of your internal chime kit, preferably with the cover off so we can see the wiring setup you have. The Pro Power Kit should normally connect to the Front and Trans of the internal chime kit. You can learn more about how to connect it in our Help Center Article here.
