22 Ft 4-Pin 5-Wire Trailer Wiring Harness with Nylon Mesh Sleeve

I picked up this 22‑foot 4‑pin, 5‑wire trailer wiring harness to rewire an older utility trailer, and it turned out to be one of the easiest upgrades I’ve done. If you want a wiring kit that’s durable, clearly laid out, and long enough for most small‑to‑medium trailers, this one is a solid choice. 🔌 Generous Length & Flexible Fit The 22‑foot main harness gives you plenty of room to run wiring cleanly along the frame, even on longer trailers. The extra length makes routing around corners, cross‑members, or enclosed channels much easier. It’s long enough for: Utility trailers Boat trailers Small cargo trailers ATV/UTV haulers No awkward stretching or splicing needed. 🛡️ Nylon Mesh Protection Is a Big Upgrade The nylon mesh sleeve is one of the standout features. It keeps the wires bundled neatly, protects them from abrasion, and adds a layer of durability you don’t usually see in basic wiring kits. It also makes the harness look more professional and organized once installed. 🎯 Clear, Standardized Wiring The 4‑pin, 5‑wire setup follows standard trailer wiring colors, which makes installation straightforward even if you’re not an expert. The wires are flexible, easy to strip, and thick enough to feel reliable without being difficult to work with. 🚚 Reliable Lighting Performance Once installed, the lights responded instantly and consistently. No flickering, no intermittent connections, and no guessing whether the ground was good. The harness provides clean, stable power to: Tail lights Brake lights Turn signals Marker lights (if wired in) Everything worked exactly as expected. 🔧 Easy to Install Whether you’re doing a full rewire or replacing a damaged harness, the process is simple: Route the harness Secure it with clips or zip ties Connect the wires Test the lights The mesh sleeve helps keep everything tidy, and the wiring layout is intuitive. 📝 Final Thoughts This wiring harness is a great blend of durability, length, and ease of use. The nylon mesh protection sets it apart from cheaper kits, and the wiring quality feels dependable for long‑term use. If you’re rewiring a trailer or building one from scratch, this is a dependable, frustration‑free option that’s absolutely worth the purchase.

Works, good quality, great price. Third one i have ordered and installed on different trailers.

Good product, but surprised at the thin gauge wire used. Hope it does not break

Nice and easy to install

Works as it should. Wired up an 8 foot-ish utility trailer. The description is correct with length and I had extra wiring which is better than not enough. The wire is good quality and the protective sheath is what your expecting. The price for this seems more than fair. Overall I'm very happy.

Good quality worked good on my Low trailer

Picked this up from amazon and was a great fit for my pickup for when we flat tow it behind our motorhome. I did like the way all the wires were separate for each side, makes it easy to wire up for towing. I did find out that you need a REALLY good ground and that is the one thing I did not have. So ran a separate wire along with the wiring and all is working great. Thanks again Amazon.

The wire got mold after one time in salt water. Poor quality. Do NOT buy for marine applications. Only 18 gauge. Most brake wires are 16 or even 14 gauge.
