Video Transcript for Comprehensive Review: Curt Relay Kit for Nissan Armada or Titan Aftermarket Tow Package

Today we're going to review part number C57000. This is the curt relay kit for Nissan after-market tow packages. This is a custom fit part. This is design to fit the Nissan Armada and Nissan Titan Vehicles starting in 2004's that do not have the factory installed tow packages. Now, these relays can also be used in other Nissan vehicles that might require tow package relays. This kit is used to complete the circuit for towing with a 7-way trailer connector. Basically, this large brown relay right here, is designed to activate the 12-volt power circuit.

These 2 smaller blue relays will activate the right hand and left hand brake and turn signal. These relays are required if your truck does not have 12-volt power or turn signals at the 7-way trailer connector. These relays will fit into the under hood fuse box on your vehicle. When you remove the cover off the panel, you'll notice on the bottom of the cover, it will list the locations and by using these nice directions, it will tell you what locations are used to put these relays into. One other note I do want to mention, is there's some Nissan trucks that might require an additional third small, blue relay just like this. We do sell these individually. It is listed on this product page as a related product.

It's part number 38666-1. These are for the running lights. The third one would be for the running lights. If your truck does not have a signal for the running lights at the 7-way trailer connector, then you'll probably need the additional relay. That should do it for the review on part number C57000, the curt relay kit for Nissan after-market tow packages. .

Product was easy to install and arrived exactly as promised.


Great Service!



by:

Excellent product, fast shipping and the video was very helpful. Thank you etrailer for great products,I buy from you again.



by:

I have a 2005 Nissan Titan which is wired for towing but missing 2 relays for running light and 12v hookup. Had to put in one blue relay and the brown/white relay and all worked.



by:

Excellent. Took less than 5 minutes to install. Very simple. Trailer lights working now. This works with a 2006 Nissan Titan without the factory installed tow package. All 3 relays together cost less than 1 relay at other places!

The service at etrailer.com is top-notch. I ordered on Monday and had my package on Wednesday. Prompt, professional, and courteous service. I'd recommend etrailer.com to all of my friends.



by:

Good quality relays, all in one package, and easy installation. Excellent customer service quick shipping.



by:

Great availability and exactly what I needed. Obviously I'm not the only person with a base model Titan that doesn't have the 3 relays needed to complete the trailer lights circuit. 2017 Nissan Titan. I spent many hours trying to figure out why I had running lights but no signal/brake lights. These are the relays you need.



by:

My experience with e-trailer has been nothing but stellar. I have a 2016 Nissan NV2500 van that came with a factory installed hitch and 7 way plus a wireing harness preinstalled by the factory in the cab taped up just behind the e-brake. Plus a Nissan harness in the glove box to be used to marry the brake controller to the harness under the dash. The van salesman said thats all I needed, Great! NOT! I worked for hours trying to get the the trailer with brakes to have all the needed lights too. Nothing worked. The dealer had no idea, forget trying to get hold of Taconsha by phone. I finally called the tech who installed brakes on the trailer and he said be sure to check for relays under the dash or hood because the factory alsways makes mistakes. Sure enough no relays were there to make the trailer brakes and light systems to work! Geez....The dealer wanted believe it or not $175.00 for the four relays! I argued that the van should have had them installed. They did not see it that way and never got back to me with my request to provide them where the van was set up for towing from the factory. So relying on e-traler I found a set of relays advertised for the Nissan Titan but nothing specifically for the Nissan NV van's in the way of relays. They do work perfectly. You'll need product #C57000 relay kit and #38666-1 single relay. And harness #3050 to mate from the socket under the dash to your Taconsha P2 brake controller. Look under your hood for the relay box closest to your battery. You'll see four empty sockets. Place your new relay's in the sockets as indicated under the relay box cover. Not much on the Internet as to how to do this on the Internet so I hope this helps other NV2500 van owners.

Perfect in every way.

the initial trailer wire harness works as described-the contact and information/questions answered promptly--I am happy--as for these relays they were bought as in case of something didn't go as planned and although you said I could return them I kept them. so never used yet--the trailer wire harness was installed on a 2012 Nissan Frontier

I've been using my Tekonsha Voyager Trail Brake system for the past year with no problems or concerns. I'm towing a 3100# camper behind my '11 Nissan Pathfinder and the system works great and was easy to install.

I have traded the vehicle that I installed those products on. While I did have those products they work fine, no problems and they performed as advertised.



by:

Only reason for a 4 star is these relays should come with the trailer lights plug because you can't buy the relays anywhere else. Easy plug and play , great direction , definitely reccomend

For a 2022 Nissan Titan that does not come with with the tow package we do offer part # N40975 which is the trailer plug with the relays.

This was exactly what I needed for my 2008 pathfinder SE. had a factory location for the relays just needed these for my trailer brakes to work with the controller.

After a year, still working good. We took the Pathfinder and the camper for a 450-mile round trip last weekend and it is still working as it should.



by:

I purchased a used vehicle, it has a combination 7/4 way connector, but was only wired for the 4 way. I needed the brown relay for the 12v to the 7 way. Purchasing the complete package was cheaper than the single brown relay at other sources. Pure plug and play.



by:

Good Morning, A trailer hooked up to my 2004 Nissan Titan SE had brake and turn lights but NO running lights... Youtube was no help! But through a mix of ETAILER and a Titan forum I learned my truck did not come with all the relays for trailer lights.. I ordered the relays for ETRAILER. The arrived quickly and the instructions made the job easy. Short story I have trailer running lights now



by:

Everything was there and plugged in exactly. Only problem was that it took me a while to figure out that not all the relay go in the fuse box and that there was a separate box for the trailer relays! That wasn’t entirely clear in the instructions but once i found the right box everything was OK.

2009 Nissan Titan



by:

Although their products did not cause a problem that I was having with turn signals on my trailer they continued to assist me until the solution to the problem was corrected. Finally they sent me a site that had the information that I needed to correct the problem. Lots of time was saved as it would have taken many hours to finally locate the offending item. I am glad that they continued to help me until the solution was found.



by:

This set saved the day on getting my Nissan ready to tow my trailer! The 7 way harness that the dealer sells doesn't let the line to charge the battery work without this!



by:

Love the service we get from etrailer.com. Had trouble with our towing lights and thought we had a towing package on our truck, turned out we didn't. These were just the ticket and worked great. Great customer service and good quality parts. We'll be ordering from etrailer again.



by:

The service was outstanding and I was able to install the relays I ordered with no issues. Instructions were simple and it took care of my trailer lights.
Thanks, and I’ll be a returning customer and will refer ETrailet to my friends.



by:

Received the product quickly and plugged them in and they worked perfectly. Would suggest that eTrailer places their shipping information on the site. i.e. If ordered after 3pm it's not processed until the next day and they don't deliver on weekends. I called in after spending 2x as much for shipping as I did for the product, just to learn I couldn't get it any sooner because I ordered after 3pm and it was a Thursday. They did change my shipping option and reduced my cost but I had to call in to get it done. Negated the ease of an online purchase. Overall good service and great product.

  • Troubleshooting Trailer Running Light Circuit of 2018 Nissan Frontier Not Active
    On certain Nissan vehicles like yours an additional blue relay is sometimes needed to activate the trailer running lights circuit. This appears to be the case with your 2018 Nissan Frontier since this circuit isn't active. This is a very common issue surprisingly. For the relay by itself you can use part # 38666-1 and the harness you need to access to plug the relay in is indeed located in the cab behind the panel to the right of the passenger's foot panel. It sometimes can be located...

  • Trailer Running Lights Not Working with 2014 Nissan Frontier
    This is actually a fairly common issue with certain Nissan vehicles but it should be a simple fix. It sounds like the relay for the trailer running light circuit is either missing or needs to be replaced. This relay should be located behind the passenger side kick panel along with the harness. The relay should be blue in color. I have attached a picture that shows where the relay will plug in. If you find that the relay is missing or needs to be replaced, you can use one of the blue relays...

    The trailer running light relay you are wanting to install in your 2018 Nissan Frontier is behind the kick panel to the right of the passenger floorboards. If you fast forward to the 4:10 mark of the install video attached on this page you'll see exactly how the relay installs. The blue relay from the Curt Relay Kit # C57000 is the correct relay to use.

    Thanks for reaching out, Brad! Yes, the Redarc Tow-Pro Liberty Brake Controller with Custom Harness # RED53CR is compatible with your 2026 Infiniti QX80. If your vehicle doesn’t already have a factory tow setup, you’ll also need the Relay Kit # C57000 and the Pollak Dual Connection Socket # PK23AV. The relay kit is what completes the necessary circuits so the rear plug actually receives power and functions properly. Also if you want to make the install look more OEM you can get the universal...

  • Trailer Running Lights Not Working on 2012 Nissan Xterra
    The issue is likely the relay for the running lights. The relay is attached to a wiring harness which is located behind the passenger side kick panel near the passenger door (see picture). You should see a harness with 2 blue relays and a larger brown relay. If both relays are there, then the relay is likely bad and should be replaced with the Curt Relay # C57000. If you do not see a harness with relays, then it is likely that the harness wasn't installed. Unfortunately, this harness...

  • My Nissan Frontier Already Has 3 Relays And Running Lights Still Do Not Work
    Are there still open spots on the fuse panel? A lot of times there will be 1 brown relay that activates the 12v power for the trailer connector, and there will be 2 blue relays which are for the turn signals. So even though there are already 3 relays, 1 additional blue relay is still needed for the running lights. Your owners manual should tell you the exact relay location but you may need a single one of the blue relays that comes with the Curt Relay Kit # C57000. Either you will need...

  • Troubleshooting Trailer Turn Signal and Brake Lights Not Functioning on 2011 Nissan Frontier
    Sounds like you are missing the blue relays that activate the stop/turn circuits of the trailer wiring of your 2011 Nissan Frontier which we offer as part number # C57000. If you check out the attached picture you can see where they install. Or you can watch the install video I attached to see how the area is accessed too. It's behind the passenger side kick panel.

  • Trailer Running Lights Not Working with 2015 Nissan Titan
    Since the turn signals and brake lights are working fine on your trailer, you should just need the one of the blue relays from the Curt Relay Kit # C57000 to activate the running lights. On your 2015 Nissan Titan, the harness under the dash where you will add the relay should be located near the emergency brake pedal.

  • Troubleshooting No Trailer Running Lights for 2017 Nissan Pathfinder
    I know you said you checked fuses but did you check relays? The "no running lights" problem is pretty common on Nissan vehicles like your Pathfinder and the issue is typically a missing or bad relay for this circuit. It's so common we almost get this question daily. For the needed relay you can use one of the blue relays from the Curt Relay Kit # C57000. I attached a picture where the harness is that has the running light circuit relay you'd need to find.

    Under the dash of your 2012 Nissan Titan there is a relay harness that you will need to check. The top blue relay would be the running light circuit. You can easily test to see if it's bad by swapping one of the nearby blue relays into it's slot to see if the problem goes away (it will then move to a different circuit since the relay is bad). If you need to replace it, you can use one of the blue relays from the Curt Relay Kit # C57000. I attached an install video that shows trailer towing...

  • 2006 Nissan Armada Requiring Additional Relay For Trailer Wiring
    Some models require a fourth relay, one of the blue relays from the Curt Relay Kit # 57000. It is installed under the dash on the left side of the steering column. There is a socket there to plug in the relay that will activate the tow package tail lights on the Armada, if it was not installed at the factory. Since you already installed the Relay Kit, part # C57000, adding this 4th relay should take care of the problem with the running lights.

  • Trailer Lights Won't Work When Connected to 2011 Nissan Titan
    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...

For this relay, you can use one of the blue relays from the Curt Relay KIt # C57000. To access the area where the relays will be installed you will need to remove the passenger side kick panel and locate the 12-pin connector that will have the harness plugged into it that the relays install to.

I then jumped on the internet and found a couple of interesting notes on the 2006 Armada. Apparently there is a relay socket under the dash just to the left of the steering column.
