I realize this is the classified section, but seems like most post in here are about towing, not items for sale...

So I just picked up a 2016 Frontier SV. I found some electrical plug in harness under the dash dangling. Is the truck already pre wired for a brake controller?

Is there any difference in brake controllers, or do they all generally do about the same thing (obviously I haven’t done any homework. Lol).

I’m new to the truck world and towing.

IDK but you might be able to move it yourself to maybe
General discussion General Discussion - Nissan Frontier Forum
Or DIY tech tips DIY - Do It Yourself / Tech Tips - Nissan Frontier Forum
You might get more input other than that maybe a mod will come by an move to the appropriate forum

But to try an answer your question Yes it is somewhat pre-wired there are brake controllers that have a plug that plugs into Nissan's plug others you might need to splice I have a Prodigy in mine that they have a Nissan plug to make plug n play. But there are also relays you need they are located in passenger kick panel an under hood an you also need the corresponding plug receptacle in rear to what your towing either 4 flat(just running, turn an brake lights), 6 round(not commonly used anymore) or 7 round the one used for trailers with brakes.

There are different classes or features to a brake controller some that can only mount horizontally some that can work in any mounting even vertical some do more axles than others not that we could tow that much anyway. The P2 I have is the of later mentioned I have used it for the last 10+ yrs on multiple trailers in multiple vehicles without incident it is very easy to set up allows for multiple settings in braking gains to match towing vehicle and has a built in manual boost. It is considered a proportional controller so it will match braking of towing vehicle the amount of force on the trailer brakes unlike timed preset setups.

Check out etrailer here's a link to the P2 installed in one of our frontiers

etrailer has a whole bunch of videos on Youtube for adding the towing accessories to the trucks. They even redid the videos for subsequent model years despite nothing really changing. They cover trailer brakes, the lighting relays, the 4 pin and 7 pin pigtails, the hitches, etc. Good stuff.

Following up on TWX, I just happened to be looking at this for my father-in-law's Frontier.

eTrailer has this plug and play wiring kit: 118266. This includes a plug-and-play 7-pin harness and the relays. There are videos as mentioned regarding the install.

There are a host of brake controllers from Tekonsha such as 90195, 90885 or 39523. For Tekonsha You need the wiring adapter 3050-p to plug it directly into the Frontier.

Or a Curt controller such as c51140 or c51120. Again, you need the Curt adapter c51382 to connect the controller to the plug under the dash.

The controller prices vary widely depending on features. But that should get you started.

Maybe I wasn't clear. After looking at a lot of Frontiers, I did not see a single model one without a tow package (2016, 2017), so I assumed it was just standard, but I have a tow package, with 7 round on the truck already.


Checking out that etrailers website, the controller is completely plug and play. It only requires the controller and the harness adapter for the Frontier. No splicing, or running wires anywhere else, which is simple enough.

It is possible to get a Frontier without a towing package (SV trim lacking Value Truck Package, or lower trims) but they are very common from the factory. You are correct, it is pre-wired to get the brake-signal from the controller to the trailer, just need the controller itself and the necessary pigtail to connect to the supplied connector in the driver's footwell area. Even trucks lacking the towing package have the necessary wiring harness already in-place, just need a few modular parts to complete. Even the frame is pre-tapped with mounting bosses for the hitch.

But they didn't have the simple information like this. Said they never heard of it. Now all of my lights are fubar.
