There are a couple of things you can look at here, but if you've blown any of the towing fuses on your 2011 Nissan Titan, it's likely that the overload was caused by some wiring issues that can develop over time. If this is a new installation that isn't operating, your Titan may not be equipped with the towing relays that are required-but they can be purchased with # C57000 .

If this is an older install where the lights have stopped working, I would first go ahead and check those fuses and replace any of them that have gone bad- the fuses are located under the cover behind the battery (you'll need your owner's manual to help you determine which fuses to look for). I would also take this change to inspect the ground wire on both the vehicle and the trailer; make sure that both grounds are connected to a paint and dirt free surface and are firmly attached.

Once you've verified all of the fuses are good, you'll also need to check the wiring on both the vehicle and the trailer to determine if there were shorts that caused this to happen, or something else. You'll want to start by testing the 7 way connection on your 2011 Titan with a circuit tester like # PTW2993 to determine whether or not the wiring harness is supplying power to the trailer; you'll need someone to help you go through the functions like the brakes, brake controller, etc.. If you can determine that the harness is functioning correctly, you'll need to plug in the trailer and start testing the wires behind the harness in the same manner that you did on the truck, having someone activate all of the functions to check for power.

If all of the wires on the trailer are supplying 12v when activated, and no ground connection issues are apparent, please let me know and I will give you a couple other things to look for.

Your brake lights and turn signals for each side are on one circuit. The left side turn signal and brake light is generally the yellow wire going into your trailer connector. The first thing to do is check the fuses on your tow vehicle. Next,…

It is strange any time a turn signal works but the brake light on the same side doesn't. this is because the brake and turn signal lights are on the same wire/bulb. The usual culprit is a bad ground. Ground problems normally show up when there is…

The Reese Strait-Line Weight Distribution system you reference, part #RP66073, is rated for a trailer tongue weight of 400-800 pounds and a gross towing weight of up to 10,000 pounds. From my on-line research I found that the 2011 Nissan Titan has a…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

If you just need a 4-pin to 7-pin trailer wiring adapter, then you can use part #C57672. This will plug into the 4-pin trailer connector on your brother's vehicle and give him the 7-pin socket for the trailer. Keep in mind, this will only give…

Hey Antoine, so the two kits you mentioned are actually really similar and honestly I would go with the part #ETBC7 if I were you. The #ETBC7L is basically the same thing minus a couple wires and breakers so you may as well get the kit that has…

It could be a tow package fuse on the vehicle. Use the owners manual to find the locations of fuses/relays related to the tow package wiring to check them and replace as needed. If the issue is not a fuse or relay then you can test the vehicle side…

If you have a vehicle specific wiring harness for a brake controller then that would indicate that you have a factory tow package and subsequently would already have a 7-way at the back of your vehicle. The universal 7-way connector #ETBC7 is meant…
