Hi Alan; Pollak is just a brand and the US Car connector is a style of connector. Pollak uses this style on their OEM connectors, the only question is whether or not you can remove the plug from the back of the connector on your 2024 Nissan Frontier. If you can pull it from the back of the connector it should look like the picture below.

Assuming you can, you could add the # 118384 in line for an extra 4-way for your light bar. However, a 4-way doesn't have a reverse light circuit. If you can't remove it then the only option is to splice in the # C59236 separately to add a 4-way for the light bar. I'm not sure what you need the separate reverse wire for but the only thing like that would be a 5-way which I don't think your tailgate light bar would have.

Hey Alan, how did things go with wiring the light bar on your Frontier using the harness options we talked about? Your update could make it easier for others trying to add a similar setup.
