Description
Sometimes your trailer wiring just comes up a little short when you need to connect to the tractor. Whether it’s a grain cart that sits a bit further back, or you need to route around a hitch component, this 12-inch extension cable gives you the extra reach to make that connection clean and secure. This J & T Products extension is made specifically for 4-pole flat trailer connections, so it’ll work with most farm trailers and implements.
What You’re Getting
- Male and female 4-pole flat connectors that mate perfectly with standard farm trailer wiring
- 12 inches of durable cable that handles the flex and movement of hitching up
- Weather-resistant design that keeps connections solid in rain, mud, and field dust
- Direct plug-and-play setup – no cutting or splicing needed
Built for Real Farm Work
This extension works with any farm equipment that uses the standard 4-pole flat trailer connection – grain carts, hay wagons, manure spreaders, and utility trailers. The 4-pole setup handles your basic trailer lighting: running lights, left turn, right turn, and brake lights. It’s the same connection you’ll find on most smaller farm trailers and implements.
Made to Last
Farm connections take a beating from road vibration, weather, and the occasional bump during hitching. This cable uses quality wire that stays flexible in cold weather and connectors that resist corrosion from moisture and fertilizer spray. The 12-inch length gives you flexibility without excess cable that can get damaged.
Good to Know
Installation is as simple as unplugging your existing connection and plugging in the extension – male end goes to the tractor, female end connects to your trailer cable. Keep the connections clean and check them occasionally for corrosion or damage. A little dielectric grease on the pins helps prevent corrosion if you’re working in wet or salty conditions.
