Features to know about

Adds the Missing Tow Package Circuits

Some Armada and Titan models come with factory tow plugs already in place but still need relays installed before trailer wiring will function correctly. This kit includes the large brown relay for the 12V power circuit and 2 small blue relays for the turn signal circuits, completing the wiring needed to power your trailer connections at the rear of your vehicle.

Handles Both 7-Way and 4-Way Trailer Connections

Switching between utility trailers, campers, and equipment haulers usually means adapting to different trailer plugs. This dual-output socket gives your tow setup both a 4-way flat connection for basic trailer lighting and a 7-way RV blade socket that supports reverse lights, electric brakes, and auxiliary power from the same mounting point.

Factory USCAR Plug Keeps Installation Simple

Splicing into your vehicle wiring can turn a quick trailer wiring job into a troubleshooting session later. The USCAR connector plugs directly into compatible factory tow ports, keeping installation cleaner and reducing the chance of wiring issues caused by cut or tapped factory harnesses.

Connector Covers Keep the Socket Ready for the Next Tow

Trailer sockets mounted near your hitch stay exposed to water, road grime, and debris between trips. Spring-loaded dust covers close over both connector openings when they're not in use, while the rubber gasket helps seal out moisture around the socket body to protect your trailer connections.

Bracket Holds the Socket Near Your Hitch

Loose trailer wiring hanging below the bumper can get damaged quickly once you start towing. The included steel mounting bracket gives your socket a fixed mounting point near the hitch or bumper, and the gloss black powder coat adds corrosion resistance where the bracket stays exposed under your vehicle.

  • Will Redarc RED53CR Work For A 2025 Infiniti QX80 With The Factory Tow Package?
    Hey Mark, thanks for reaching out. Sounds like you are on the right track here. The Redarc # RED53CR is exactly what you'll need for your 2025 Infiniti QX80, and it does include the TPH-014 custom pigtail. That said, it looks like Infiniti doesn't always include the tow package relays or the actual 7-way socket in their tow package, so if you don't have those you'll also need the CURT 7-Way/4-Way Trailer Connector and Relay Kit # C34FR72ZY to complete your installation. That would be...
