I am trying to figure how to properly use two source to activate a single relay but not to back feed power from one source to another. Is there a special relay I need ?

You can do what you want with a single relay. The simplest way to keep from backfeeding your sources to each other would be to use diodes.

Just generic 1 amp switching diodes will work fine. I don't have a part number.
