This kit includes the 2 small blue relays and 1 large brown relay that are required to complete the circuits for your Nissan Armada or Titan's non-factory-installed tow package.
Features:
Note: Some Nissan vehicles will require a 3rd blue relay (38666-1).

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. .

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.

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.

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.
