Dodge Repair: Speaker Replacement, power mirror, speaker harness

Question
QUESTION: I am replacing the blown rear door speaker in my 2002 5.9 RT.  The connector for the factory is a single clip type and will not work with aftermarket speakers.  How can I tell the difference at the speaker location between which wire is positive and which is negative so that when I cut the connector off I can hook them up correctly on the new speakers?

ANSWER: 02 5.9 what?  dakota or 1500?
