Question:

I have a 7 pin tow connector on my 2025 Nissan Pro 4X. I am needing a 4 pin connector I can mount next to the 7 pin for when I need to connect my topper wiring. Do they make a kit for this? thanks,

Hey William! What you can do is add the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236. This is a universal wiring harness that will splice in and provide you with a 4-way to power the lights on your topper. This will also bypass any factory wiring so your truck doesn't detect a trailer while hooked up to the topper.

You can use a bracket like # C42CR if you want to mount it at the rear. However, you might want to hold off and see how that wire runs for the topper before you mount an additional bracket.

What kind of topper do you have and what do you use it for?
