Description
If you’ve got a tractor with a 5-wire trailer connection and need to pull a trailer with 4-wire lighting, you know the frustration of trying to make the two play nice together. This handy adapter solves that problem by converting your 5-wire output to work perfectly with standard 4-wire trailer setups, so you can hook up and haul without the headache of rewiring anything.
What You’re Getting
- Direct conversion from 5-wire to 4-wire trailer connections without cutting or splicing
- Weather-resistant construction that handles everything from spring mud to harvest dust
- Secure connections that won’t come loose when you’re bouncing across fields
- Universal design that works with most farm tractors and agricultural trailers
Built for Real Farm Work
This adapter bridges the gap between modern tractors and older trailers, or newer trailers and older tractors—whatever combination you’re working with. It’s perfect for grain carts, hay wagons, manure spreaders, and utility trailers that need reliable lighting for road travel. Whether you’re hauling to the elevator or moving equipment between farms, proper trailer lights aren’t optional.
Made to Last
Farm connections take abuse from weather, vibration, and the occasional bump from equipment. This adapter uses quality materials and solid construction to handle the electrical load while standing up to the conditions that kill cheaper adapters. The connections stay tight and keep doing their job season after season.
Good to Know
Installation is straightforward—just plug the adapter between your tractor’s 5-wire connection and your trailer’s 4-wire plug. Make sure all your lights work before heading down the road, and keep the connections clean and dry for best results. A little dielectric grease on the terminals helps prevent corrosion if you’re working in wet conditions regularly.
