JURPLIX 7 & 4-Pin Trailer Wiring Harness Connector — Dual-Socket Receptacle with Mounting Bracket

The JURPLIX dual-socket tow hitch receptacle combines a 7-way blade and 4-way flat connector in one rugged assembly for quick, reliable trailer hookups.

Designed for pickup trucks and common towing setups, this JURPLIX kit provides a compact, hard-mounted solution to power trailer lights, turn signals, and auxiliary circuits. The assembly mates with standard USCAR sockets for plug-and-play installation and includes a reinforced metal bracket and hardware so connections stay steady under vibration. Premium copper terminals deliver improved conductivity and reduced heat, while the combined sockets give you flexibility when switching between trailers that use either a 7-pin or a 4-pin plug.

How does the dual-socket design simplify towing connections?

The combined 7-way and 4-way receptacles let you use one mounted unit instead of switching brackets or adapters each time you change trailers. You can connect trailers with either blade-style 7-pin plugs or flat 4-pin plugs without rewiring, which saves time at the hitch.

• One mounting point supports both 7-pin blade and 4-pin flat plugs
• Suitable when towing multiple trailer types over time
• Note: both sockets cannot be used simultaneously—plug only one trailer at a time

What makes the electrical contacts durable and safe?

JURPLIX uses high-quality copper terminals to improve conductivity and reduce resistance-related heating during operation. Better electrical flow minimizes the chance of voltage drop, supporting reliable lighting and signal operation while towing.

• Copper contacts for stronger current transfer and lower heat buildup
• Reduces risk of corrosion and shorting compared with lower-grade metals
• Designed to maintain consistent connection under load

How straightforward is installation for most pickup trucks?

The kit is built to work with standard USCAR socket wiring, enabling direct plug-in to existing systems in many vehicles without cutting or splicing. Included mounting hardware and a heavy-duty bracket make it simple to position and secure the receptacle at the vehicle’s rear.

• Plug-and-play compatibility with common USCAR wiring standards
• Reinforced metal bracket and fasteners to resist vibration and loosening
• Installation typically requires basic hand tools and a few minutes of time

What should I expect from performance while towing?

Once installed, the assembly delivers steady power for trailer lights, turn signals, and running lamps so your trailer remains visible and communicative on the road. The robust bracket and secure connector contact reduce intermittent faults that can occur from vibration or loose sockets.

• Stable power transfer for lighting and signaling functions
• Bracket minimizes movement that could cause connection failure
• Compatible with standard trailer wiring loads common to pickups

Who is this for: This JURPLIX receptacle and bracket kit is aimed at pickup owners, fleet operators, and DIY trailer users who need a durable, easy-to-install towing connector that supports both 7-pin blade and 4-pin flat trailers. It’s a practical upgrade for anyone wanting reliable lighting and signal performance with minimal wiring work and a secure, vibration-resistant mount.
