Hi, I have a 2003 gmc sonoma. it is a 4.3L v6. I got a "back-up camera" for christmas, and it needs to connect to a negative and positive source. The product says that the rear lights is the best spot. I took off the light, and located the stop light/parking brake light. The problem is that there is three wires going into the light, and the camera only has 2. So my question is which 2 of the three wires do i choose? The wires are colour coded, yellow, black, brown (in that order). I also need to know which is pos/ and negative too. Thank you for all your help.
