Is the OEM Trailer Wiring Pattern the Same for Dodge Ford and GM vehicles
It has been proposed to me that there is a possible difference in the wiring pattern on a seven contact trailer connection on Dodge trucks and GM trucks and Ford trucks or is the pattern the same for all trucks reguardless of vehicle manufacture?

The OEM wiring configuration of all Chevrolet, Dodge and Ford vehicles, as well as Nissan and Toyota, is the same, and is identical to the pattern shown in the photo I have attached. This is all based on wiring that has not been changed from the original configuration by the owner of the vehicle.
Many times we see vehicles come in with the wiring on the vehicle changed because the person has a trailer that is wired incorrectly. Instead of changing the trailer wiring to match the industry standard, the vehicle wiring is changed to match the trailer, essentially making that vehicle only compatible with that trailer or one similarly wired.
