I was going to the web site chasinggame.com and I stumbled on this web site nativeoutdoors.com They have the cables and things a person needs to wire their own. I spoke with a tech from wildview about their external source. He said their cameras have a resistor installed to drop the voltage down. With that being said, since the wildgame cameras aren't made for an exteral source. I think I'll just wire in a 6v external source and swap batteries out when I swap SD cards. That way I won't take a chance on damaging my camera in case it isn't equiped with a resister. I'll just put a 6v in with a little higher amperage since thats where it draws it source anyway.
