Hello, I am rebuilding a 2012 quad cab 5.7 and the wires were cut by the fuel vapor sensor plug. I have a donor plug, but the wire colors are different. This sensor is visible from the left rear wheelwell. It is mounted on the fuel filler neck. The wires on my truck are blue, brown and a creme color but I do not know which order to splice them to my donor piece. A picture would solve my check engine light.. Thank You.
