MECMO 4‑Pin Coiled Trailer Wiring Extension — 5ft Retractable 4‑Way Flat Plug, Male & Female

MECMO's 5ft coiled 4‑pin flat trailer extension is a retractable male-to-female wiring adapter that gives you a neat, reliable way to extend trailer lights without cutting or splicing.

Whether you tow a boat, ATV, horse trailer or utility cargo trailer, this 4‑way flat wiring extender solves short-reach and messy-cable problems. The springy coiled design stretches up to about 60 inches when needed and snaps back to a compact shape for storage, while the industry-standard 4‑pin flat connectors fit most vehicle and trailer sockets.

How does this extension keep wiring tidy when towing?

The coiled configuration prevents loose cable drag and tangles by retracting when slack. That keeps the wiring off the ground and reduces wear from road debris and moving parts.

• Retractable coil stretches up to ~5 ft (60 inches) and compresses for storage
• Flat 4‑pin profile lies closer to vehicle to reduce snagging
• Durable PU jacket resists abrasion and outdoor exposure

Will this fit my trailer and vehicle sockets?

Yes — the MECMO extender uses the common 4‑pin flat (4‑way) connectors found on most small trailers and towing vehicles. It includes both male and female ends so you can plug directly into either side.

• Male and female 4‑pin flat connectors for universal compatibility
• Works with boat trailers, ATV, motorcycle, horse and utility trailers
• Plug‑and‑play installation — no cutting, splicing, or wiring tools needed

How robust is the cable for regular towing use?

This wiring extender is built with 18 AWG pure copper conductors enclosed in a soft PU outer jacket for flexibility and durability. The materials are chosen to flex repeatedly without deforming and to resist cracking in outdoor conditions.

• 18 AWG pure copper inner wires for dependable signal conductivity
• Soft, flexible PU cover reduces stiffness in cold weather
• Coil design rebounds quickly and resists permanent stretching

How simple is installation and everyday use?

Installation is straightforward: align the 4‑pin flat connectors and push them together. The cable is ready to use immediately and can be stretched only as far as needed to reach, then retracts back to avoid excess slack.

• Plug‑in design — connect vehicle‑side to trailer‑side without tools
• No wiring modifications required; preserves factory harnesses
• Compact when retracted for easy storage in a glovebox or toolbox

Who is this for? The MECMO 5ft coiled 4‑pin trailer extension is ideal for weekend boaters, trail riders, landscapers and anyone who tows smaller trailers and wants a clean, low‑maintenance wiring solution. If you need a short, flexible light extender that snaps back into place, fits standard 4‑way flat sockets, and avoids cutting into factory wiring, this cable is a practical, budget-friendly choice.
