To find the correct wire, you must consult a wiring diagram specific to your 2010 Dodge Ram 1500. These diagrams are usually available online through repair manuals (like a Haynes or Chilton manual) or sometimes through online forums dedicated to Dodge Rams. The diagram will show the correct wire color and location.
Attempting to identify the wire by color alone is risky and could lead to damaging your vehicle's electrical system. Using a wiring diagram is essential for safe and correct identification.
