The black relay is NOT factory. It does not have a plug, each wire is individually connected by squeeze-on connectors. I have no idea what it is used for. I have seen a lot of weird things added to cars. Maybe it is part of a Burglar Alarm and it is an ignition cut-out? If you don't know what it does the "best" thing is to try to remove it. Just taking it out may disable some function so you have to try to restore the wiring to the way it is supposed to be. The silver relay IS factory and is the ballast bypass. Active only during cranking.
