What Wiring do I Need for a 7 Way on the Back of My 2010 Nissan Frontier for Brake Controller?

Hello Mike,

I’m glad you wrote in because there’s a better and easier option for you.

To get a 7-way on the back of your 2010 Nissan Frontier and have it ready for a brake controller, you’ll want to install the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118266. I’ve attached an install video so you can see exactly what’s involved.

You don’t need to install a brake controller right away, your truck will be ready for it whenever you are. When that time comes, the Tekonsha Prodigy P3 Trailer Brake Controller w/ Custom Harness – Up to 4 Axles – Proportional # TK59ER will include the vehicle-specific pigtail for an easy install. The # 90195 you were looking at comes with a universal harness that would require splicing, and nobody wants to deal with that.

What kind of trailer are you planning to tow?

So after talking w ginny in sales I opted for the 118266 t one and since I figured I go ahead and do the controller now, I opted for the curt tri flex c54qv. So all should be simple plug and play. No splicing or running wires. Tow vehicle is the 2010 Nissan frontier LE, towing a 2015 sportsmen classic 18rbt. Thank you so much.

@MikeL For some reason our Tekonsha brake controllers were not showing up in the fitguide for your Frontier, I am currently in the process of getting that fixed. The Curt Tri Flex will get the job done. The P3 is great for if you have different trailers because it can save the different settings for you, if you do not have multiple trailers then it might be a little too much. I am glad that she suggested the right wiring over the # ETBC7, the install is going to be much easier with the # 118266. If you run into any issues with the install, or have any other questions, you know where to find me!
