I have recently purchased an OEM hitch receiver and plug. I am looking to wire up the 7-pin plug as OEM as possible. I know there is a separate harness for the trailer plug, that I assume runs up to the engine bay. However I have seen things about certain trucks not having a 23P conenctor to plug into. Does anyone know anything about this connector, or where it is located? If I have to wire things up myself, I can but I'd rather just buy the harness if at all possible.
Also, I'd assume I don't have the pigtail in the cabin for the brake controller as well correct?
