    You don't give much information in your post. I can tell you that you're not going to find detailed plumbing nor electrical schematics for your trailer. You can call Grand Design Customer Service with your VIN and see if they can provide you with some block diagrams for the particular area you need.

    PS: I added some clarity to your thread title and moved the thread to Plumbing & Water Systems.
