What advice did Johnny want Pony to give to Dally?

He wants Johnny to tell Dally that fighting is not the answer to life's problems. He instructs him to tell Dally that he can "stay gold" and not fade away. It is, however, too late now. Ponyboy realizes that Dally has died because he let his gold fade, but that it doesn't have to be that way for all the Greasers and disadvantaged people.
