and i gathered all of this information from directechs.com, and although they are usually right, ALWAYS double check your work with a meter or some type of tool to make sure your tagging into the right wiring. i hold no responsibility for what you do with this information and if you break stuff. make sure your doing it right, and if your not sure how to test, bring it to a pro!
