In order to link a gamertag or PSN ID to your Origin account, you need to do this:
1. log in to your Origin account
2. click Friends -> Add a friend in the menu bar
3. the pop-up will give you the option to connect to Facebook, XBOX Live or Playstation Network. Choose your preferred option
4. fill in your log-in details and follow the steps on screen
You're good to go. If you are unable to connect, it could be a temporary issue with the servers. Try again later and if the issue persists for more than 24 hours, contact EA support.
If everything went fine, then you should be able to see your Xbox or PSN account listed under Connected Accounts in your account management page (click Account and Privacy in the menu bar).
