    What are these wires on my 2018 Chevy 2500

    Added a ranchhand rear bumper and want to wire some accessory running and tail lights on the bumper. I know I could tie in to existing, but while under the truck I found this cluster just sitting there. The thicker ones look like power, but does anyone know if the others are lighting???

            Put a test light on them to check.

                  Bored much?!

                  As for the wires, I tend to agree with it could be for trailer wiring. As mentioned put a test light on them and see what does what.

                    Trailer lights. Look at what wires run to your current 8 pin plug, can probably match the colors up just as easily.

                      To answer your question.
                      I have no idea.

                      My guess is they are for trailer.

                      I use this guide when working on trailer wiring.

                      Like others had suggested use a test light to verify.

                          They are for a trailer.
                          The White is Ground
                          Blue is Trailer Brakes (power)
                          Black is 12v constant (charges battery in camper etc..)
                          Green is right turn
                          Yellow is left turn
                          Brown is tail lights

                            Except I actually looked at the picture. lol
                            You have 2 whites, and no black, small one is probably ground and big may be power 12v..use a test light on that.
                            If there is a red it is for accessory or backup lights.
