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. .

This kit includes the 2 small blue relays and 1 large brown relay that are required to complete the circuits for your Nissan's non-factory-installed tow package.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.
Easy to use and arrived one day early. And all three electrical parts were easy to install .
Our local auto parts store wasn’t able to provide the connectors.
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
Jenny N - 05/02/2022Right part, easy install for my 2017 Nissan Titan, which did not come with the factory trailer relays. Thanks.
the ordering process was as good as the shipping and the product was excellent. I will use etrailer again!
Relay fit as it should and allowed for the easy install of trailer brakes
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.
Robert - 09/17/2019Easy installation. Very solid hitch.
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.
Excellent customer service, product was shipped and received in a timely manner.
Just wish I had watched there [online} channel before spending $500.00 with another company who clearly didn’t know what to do.
Information in solving a very difficult problem in getting the running and brake likes to work on a Nissan Armada was resolved quickly with good information and advice.
Worked perfectly and directions were easy to follow. Will definitely use etrailer.com in the future as I have in the past.
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.
John P - 04/02/2018Fit exactly like the original
Came sooner than I thought.
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.
Great quality, took no more than 2 minutes to install, clear instructions. Highly recommend the product and etrailer of course, fast shipping and great attention.
Gabriel - 06/04/2014These guys are the real deal! They say what they’ll do, and they do what they say! I have ordered from them a few times with small delicate items as well as a hitch and everything has fit and worked properly as advertised. Definitely my “go to” for parts and accessories.
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.
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.
Worked great! Can't believe that these were not factory installed on the Titans...so much hassle trying to figure out the problems with the trailer lights, over nothing!
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.
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.
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!
Extremely satisfied with my purchase, I will definitely be purchasing other merchandise from etrailer. I will also be recommending this site to my friends and family. Thank you!
These relays are perfect, they fit and function in the factory sockets, and were a snap to plug in. Shipping was also very fast, and I was informed every step of the way. I will be buying more from etrailer.
