When you buy the proper adapter, it will be labeled----no reason to cut up the factory wiring.

Or, use a small battery to test the factory speaker.  If the battery makes the speaker pop out toward you, then + from the battery is the + speaker wire..................... if the speaker pushes in away from you, the battery's + wire is conneced to the speaker's - wire.
