I knew there was something about that black wire only being 20G? So if I am understanding you, the black wire is actually a ground that needs to be grounded?? And now I need to feed the parking brake lamp somehow with the blue w/white trace? How and where can I make the connections for this part of the circuitry? I will update the above post where the parking brake is, to reflect the correct information. How should that area read? Hey Thanks....
