My New truck has not been fitted with any trailer wiring (or a towbar, I'm sorting that) so I purchased and aftermarket 7pin plug and harness that splices into the OEM loom. https://www.etrailer.com/question-434685.html
I can see 12v on one of the pins and 9v on another 2 but regardless of lights, indicators being on or off, there is no voltage change at the plug.
I'm still troubleshooting things but thought I would reach out for advice. Is there fuses that should be in place for the trailer wiring to work? or does a trailer module have to be in place before signals get send to the trailer wiring?
Thanks
