The best 6-point trailer plug depends on whether you need a durable replacement, an easier-to-grip connector, or both vehicle- and trailer-side parts. The CURT 58080 is best for a metal trailer-side replacement, while the MECMO plug suits buyers seeking a splice-in design. CURT’s plastic 58120 is a lighter-housing alternative, the 58082 adds an extension spring, and the 58092 is the pick when you need a matching vehicle-side connector too. Confirm your existing connector is a 6-way round type before choosing.

CURT 58080 Metal 6-Way Trailer Plug
Best for: Trailer owners replacing a trailer-side 6-way round connector who want a metal housing and an easier grip. This CURT plug has a durable die-cast metal body and side tabs designed to help with connecting and disconnecting.
Its industry-standard 6-way round design supports connections for taillights, brake lights, turn signals, electric trailer brakes, and an auxiliary power wire. That makes it a practical choice when those circuits match the trailer’s wiring setup.
Why it was selected: It combines a stated standard round configuration, grip-focused features, and metal construction in a straightforward replacement plug. Limitation: It is a trailer-side plug, so it is not the all-in-one choice if you also need a vehicle-side connector.
MECMO Splice-In 6-Pin Metal Plug
Best for: Buyers looking for a splice-in trailer-side replacement for a compatible 6-way round setup. MECMO describes this plug as having a built-in splice-in wiring harness intended to make wire connection and fixation more direct.
The manufacturer identifies applications such as horse, farm, gooseneck, boat, and utility trailers, and notes that this connector type is commonly found on some older pickups and SUVs. Its metal shell and reinforced internal structure are presented as features for outdoor towing use.
Why it was selected: The splice-in format and stated trailer applications make it a relevant option for replacing a worn trailer plug. Limitation: Verify the connector shape and wiring arrangement on your vehicle and trailer; the product description’s vehicle examples do not establish fit for every model or year.
CURT 58120 Plastic-Housing 6-Way Plug
Best for: Trailer owners who want a CURT 6-way round replacement with a plastic housing rather than the die-cast metal body of the 58080. This model has a bright chrome finish and side grip tabs for handling.
Its listed uses include connecting taillights, brake lights, turn signals, electric trailer brakes, and an auxiliary power wire. The standard 6-way round design makes it a useful comparison when the existing connection is the same type and the circuit layout is compatible.
Why it was selected: It offers the same general connector function as a metal-housing alternative, but with a different housing material. Limitation: The housing is durable plastic, not die-cast metal, so choose the metal CURT option if metal construction is a priority.
CURT 58082 Plug With Extension Spring
Best for: Trailer owners who want to attach the plug at a convenient, accessible location. The extension spring is designed to help keep the connector within reach for plugging in, while side tabs support gripping the plug during connection or removal.
CURT describes this as a replacement 6-way round trailer wiring connector commonly used with horse, farm, boat, and utility trailers. It is a practical choice when connector access is a key consideration and the trailer uses the matching round configuration.
Why it was selected: The spring sets it apart from a basic replacement plug by addressing where the connector can be positioned. Limitation: The product information does not specify a complete vehicle-side connector, so it may not solve a need to replace both ends.
CURT 58092 Vehicle And Trailer Set
Best for: Buyers who need to replace both the vehicle-side and trailer-side connectors. This set includes 6-pin round connectors for both sides, with side tabs intended to make plugging and unplugging easier.
The listed functions include taillights, brake lights, turn signals, electric trailer brakes, and an auxiliary power wire. Both connector housings are described as die-cast metal, which may appeal to buyers prioritizing metal construction on each side.
Why it was selected: It is the most complete option in this list when both mating connector ends need replacement. Limitation: Choose a single trailer-side plug instead if only the trailer connector needs repair; check the existing connector type and wiring before installation.
Buying Guide: How To Choose A 6-Point Trailer Plug
Is your connector 6-way round?
Check the shape and number of contacts on both the vehicle and trailer before ordering. “6-point” or “6-pin” can be used informally, but these products are described as 6-way round connectors. A different connector shape or circuit layout may not mate correctly.
Do you need a plug, a socket, or both?
A trailer-side plug replaces the connector attached to the trailer wiring. If the vehicle-side socket is damaged too, a paired set such as the CURT 58092 may be more appropriate. Match the part to the side that needs repair.
Which housing and handling features matter?
For a die-cast metal housing, compare the CURT 58080 with the 58092 set. The CURT 58120 has a plastic housing with a chrome finish. Grip tabs appear on several CURT plugs, while the 58082 adds an extension spring for a more accessible attachment point.
What should you verify before wiring?
Confirm the vehicle and trailer use compatible wiring functions, including lighting, electric brakes, and any auxiliary power circuit. Follow the product instructions and verify each wire’s function rather than assuming colors are identical across installations.
Frequently Asked Questions
What does a 6-way trailer plug connect?
These products are described as connecting taillights, brake lights, turn signals, electric trailer brakes, and an auxiliary power wire. The exact wiring setup should be checked on the trailer and towing vehicle.
Are all 6-pin trailer plugs interchangeable?
No. Confirm that both sides use a compatible 6-way round connector and matching wiring arrangement. Pin count alone does not prove that connectors or circuits will match.
Should I choose a metal or plastic trailer plug?
Choose based on your housing preference and the product’s stated construction. The CURT 58080 uses die-cast metal, while the CURT 58120 uses plastic with a chrome finish.
Can I replace only the trailer-side plug?
Yes, if the vehicle-side connector is compatible and in good condition. If both ends require replacement, consider a product that includes vehicle-side and trailer-side connectors.
