Installation of the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56225 that fits your 2019 Nissan Frontier (without a factory connector) is very straightforward, but installing a harness on a Nissan does require the use of relays, which are included with this kit.
Start the install by attaching the relays, with the blue ones going on the white plugs and the brown one going on the brown plug. Then simply locate where you need to plug in the connectors and that's all there is to it. I have added a link to a video of this harness being installed so you can see firsthand exactly how it is done.
