Can a 4-Way Trailer Wiring Harness be Installed on a 2013 Nissan Frontier with Factory 7-Way

Question:

I have a 7 pin already connected by the factory . I wanted to add a 4 pin connector also. Do i just buy the replacement 4 pin and plug it in. Does the factory run both? And are the relay the same or do i need to add them also

All you will need to use a 4-Way and keep the 7-Way also is a simple adapter like # PK12716. You will not have to worry about hardwiring in anything or losing out on the use of the 7-Way.

If you were to install a replacement factory 4-Way you would not need any additional relays. The ones that work with the 7-Way also work with the 4-Way. If you choose to install a 4-Way you will have to disconnect the 7-Way because they plug into the same locations.
