Help please, I have a 2018, 2500hd. Trying to do the fogs and brights. The wire in position 10 is solid brown in mine, directions say it should be brown with white stripe. What are the correct positions for this truck? .Position 18 is brown and violet like the directions suggest. Please let me know if I do 10 and 18 regardless of color or what is correct for the 2018 2500 HD to keep the fogs on with the brights. Thanks .....update....
Answered my own question. Brown wire equals brown with white stripe on my 2018. Use positions in the connector. Also used small tap ons, easy.
