CURT 6-Pin Round Trailer Wiring Harness 58092 — Die-Cast Vehicle & Trailer Plug, Weatherproof Locking Tabs

CURT 58092 is a heavy-duty 6-pin round wiring set that provides a secure electrical link between your vehicle and trailer for tail lights, turn signals, brakes, auxiliary 12V and ground connections.

When towing, a dependable electrical connection is essential for safety and compliance. The CURT 58092 kit includes both the vehicle-side socket and the trailer-side plug in a die-cast metal housing, a spring-loaded cover to keep contaminants out, and locking tabs to resist vibration-related disconnects. It’s engineered to suit common applications like utility, boat, and livestock trailers that require six circuits.

How does this connector keep wiring safe from weather and road debris?

The CURT 58092 uses concealed terminals inside a robust die-cast shell and a spring-loaded steel cover to limit exposure to moisture, dirt and road salt. The protective design reduces corrosion risk and extends service life compared with open-terminal connectors.

• Spring-loaded steel cover sheds water and prevents debris buildup
• Concealed terminals minimize direct contact with corrosive elements
• Die-cast metal housing resists impact and abrasion

What wiring functions does the 6-pin round connector support?

This unit supplies the standard six circuits used on many trailers: left/right turn signals, tail/running lights, electric trailer brake control, a 12-volt auxiliary feed and a ground. That makes it suitable for trailers that need brakes or a battery feed in addition to basic lighting.

• Tail lights and running lights connection
• Left and right turn signal circuits
• Electric trailer brake feed and 12V auxiliary power
• Dedicated ground pin for stable circuitry

How easy is it to connect and keep connected while towing?

The plug and socket feature ergonomic grips and locking tabs so you can insert and remove the plug easily while ensuring it remains secure on the road. The tabs resist loosening from bumps and vibrations, and the design simplifies routine hookup even when working alone.

• Ergonomic side tabs for a positive grip during hookup
• Integrated locking tabs maintain a firm mechanical connection
• Compact round profile fits common 6-way trailer receptacles

Can I use this as a replacement for worn trailer plugs and sockets?

Yes — the CURT 58092 is well suited as a direct replacement for many 6-way round connectors. Its rugged materials and concealed wiring points make it a durable upgrade over cheaper plastic units, and it works with standard trailer wiring splices (wires not included).

• Works as a replacement vehicle or trailer-side connector
• Durable die-cast construction outlasts typical plastic housings
• Concealed terminals accommodate common splice-in wiring

Who is this for: The CURT 58092 is aimed at tow vehicle owners, fleet operators and trailer builders who need a compact, weather-resistant 6-pin round connector that handles lighting, brake control and auxiliary power. It’s a good fit for owners of livestock trailers, boat trailers, utility trailers and anyone replacing worn or unreliable 6-way hookups. Choose this connector when you want a reliable, mechanical and environmental upgrade that simplifies hookup and reduces the chance of electrical faults on the road.
