Appeal major to UCI HSSEAS

I applied as a MechE Major and was accepted into UCI, but with Undeclared as my major. I want to appeal my major through the “Appeal your major” option. Has anyone here had any successful appeals and if so, what did you write about in your essay? I have created things that I can show in my essay, but my only problem is getting the basic idea and structure of the essay.
