How to Connect Vehicle with 7-Way Connector to Trailer with 4-Way Connector


My 2016 Nissan Frontier Pro4X has a dealer installed 7 pin wiring harnessand connector. What adapter do I need to interface with my utility trailer that has a flat 4 connector ? Thanks for your help

In order to connect the 7-Way on your 2016 Nissan Frontier to your trailer that is equipped with a 4-Way connector, you will just need an adapter like the Pollak # PK12716. This will plug right into the 7-Way on your Frontier and provides a 4-Way at the other end that will hook up to the trailer. This is designed specifically for what you are needing to do.

I have attached a short video demonstration on this adapter that you can also check out.
