PKDOAX Multi-Tow Trailer Connector — 7-Way Blade + 5/4-Way Flat, Heavy-Duty Weatherproof

The PKDOAX Multi-Tow Trailer Connector combines a 7-way RV blade outlet and a 5-way flat outlet (that also accepts standard 4-way plugs) into a single vehicle-side connector for flexible towing hookups.

This heavy-duty connector is designed for drivers who tow multiple trailer types and want one, compact mounting point on the tow vehicle. It lets you quickly connect trailers equipped with 7-way blade plugs or 5-way/4-way flat plugs without swapping adapters. Durable housing, covered contacts, and a 180-degree opening lid simplify plugging and help resist road grime and moisture when parked.

How does the dual-outlet design save time and space?

The integrated 7-way and 5-way outlets eliminate the need for separate sockets or bulky adapters. You mount a single connector to the vehicle and use the matching trailer plug directly for faster hookups.

• One mounting point replaces two separate connectors.
• No adapter needed when switching between 7-way and flat-plug trailers.
• Cleaner wire routing and reduced under-bumper clutter.

Will my 4-way flat trailer plug work with this connector?

Yes — the 5-way flat opening accepts compatible 4-way flat plugs so basic lighting circuits operate while leaving the fifth contact unused. That makes the connector backward-compatible with common flat-plug trailers.

• 4-way flat plugs fit into the 5-way flat outlet for taillights, turn signals, and brake lights.
• 5-way flat users can access an extra contact when available.
• Wiring functions depend on your vehicle’s pin assignments; verify before towing.

What protective features help this connector last outdoors?

The molded plastic housing and covered contacts reduce exposure to moisture, dirt, and debris. The oversized 7-way lid swings open to 180 degrees for easy access and latches closed to shield sockets when not in use.

• Reinforced plastic body resists impact and road debris.
• Covers over each outlet limit corrosion risk from moisture.
• 180-degree lid provides unobstructed access when plugging in.

What’s included and what should I check for installation?

The package includes the combined connector, a mounting bracket, and installation hardware. Professional or experienced DIY installation is recommended since the unit requires wiring to the vehicle harness and proper pin mapping.

• Mounting bracket and necessary fasteners included.
• Confirm mounting space, clearance, and orientation before drilling.
• Verify vehicle wiring functions and pin assignments prior to final connection.

Who is this for: The PKDOAX Multi-Tow Trailer Connector is ideal for contractors, fleet owners, and recreational vehicle users who tow different trailer types and want a single, robust connection point. It’s suited to anyone who needs quick switching between 7-way trailers and flat-plug trailers, wants reduced under-bumper clutter, and prefers a weather-protected socket with included mounting hardware. If you’re unsure about vehicle wiring or pin assignments, consult a qualified installer to ensure safe, correct connections.
