Are All Vehicle 7-Way Connectors Wired The Same

Question:

are all 7 blade trailer connectors wired the same? i.e. is the 2013 tundra and the 2016 suburban 7 blade trailer connection set up the same? thanks

There is indeed a standard for the vehicle and trailer side 7-Way connectors in terms of pin/function location on the connector. The actual wire colors may differ between your 2013 Tundra and 2016 Suburban but the pin locations on the connector will be the same.

I have attached a diagram to assist along with a trailer wiring article that you might find helpful.
