Pj Gooseneck Trailer Brake Wiring Diagram. The source of the information below is the National Highway Transportation Safety Administration (NHTSA), which maintains TSBs for vehicles sold in the United States. The dealer I bought it from said it used to have a trailer brake installed and I was just assuming that was the case, but now I'm not so sure.
If I had a wire diagram I may be able to find it.
Trailer plug wiring is standardized across all vehicles, no point trying to find vehicle specific info.
Having the various pinout diagrams available is vital to troubleshooting and/or. Do you know if the "brake controller output" pin has any output on our trucks if there's no brake controller installed? The dealer I bought it from said it used to have a trailer brake installed and I was just assuming that was the case, but now I'm not so sure.
