With each kit, we include easy-to-follow instructions, and provide an online video that shows the complete process of how to rewire a trailer. Whether you are building your own trailer or rewiring an older trailer, these kits make the process simple. CURT trailer lighting kits are designed to work with trailers up to 80” wide. These kits include combination lights, marker lights, a wiring harness and frame mounting clips to easily route wiring through your trailer to the coupler. CURT offers both trailer lighting kits and combination trailer lights to get you back on the road sooner.ĬURT trailer light kits come with everything you need to rewire your trailer and have it ready to hitch up to your vehicle. Compared to the rigid design of a trailer hitch, however, trailer tail lights and brake lights can be fragile and broken if accidentally bumped with enough force. Not only do they provide a necessary element of safety on the road, but they are also required by law. Trailer lights are an integral part of towing. If your trailer wiring is damaged or trailer lights are broken, you may wish to rewire the trailer with new wiring and lights. Next, test your vehicle wiring plug to make sure it is working. Many trailer light wiring problems occur because the wires are not properly grounded. To fix broken trailer lights, begin by checking the ground. How do I fix my trailer lights not working? Having a utility trailer rewired can cost anywhere from $50 to $200, depending on labor costs and the design of the trailer. How much does it cost to rewire a utility trailer? If it is a passenger-side trailer light, insert the green wire into the turn signal / brake light connection point. If it is driver-side trailer light, insert the yellow wire into the turn signal / brake light connection point. You can wire a trailer light by inserting the brown wire into the taillight connection point. Yellow is the left turn signal and left brake light. Green is the right turn signal and right brake light.

What is the color code for trailer wiring? Weight Distribution Hitches with Sway Control.Channel Mounts and Adjustable Ball Mounts.Original Equipment Replacement Connectors.X5 5th Wheel to Gooseneck Adapter Plates.OEM Puck System 5th Wheel Legs and Silders.Class 5 Commercial Duty Trailer Hitches.If you try and draw too much amperage from the taillight circuits, you'll be in for trouble. The most difficult part is running the relay hot wire through the factory harness protectors up through the firewall to the battery connection. I suspect an aftermarket 4 way kit such as Curt, etc uses the same relay or a similar one. Of course the 7 way has 3 additional circuits for brakes, battery charge line and backup lights but they are wired in addition to the trailer light relay. The Mopar 7 way/4 way trailer harnesses both use this same setup.

I suspect if you look at the Mopar 4 wire harness kit, you'll see that it has a small box near the end. The taillight wires are tiny and won't tolerate much amperage.

If you have LED's on your trailer, you "might" not have a problem, but if any of the taillight circuits draw more than half an amp or so on the JL, you run the risk of problems. The tap wires that hook to the Jeep are just to trigger ( typically 200 milliamps or less) the relays that run the trailer lights. the hot wire goes to the battery and provides output for the circuits that go to the trailer. The Mopar and many other harnesses come with a small box that gets buried next to the right taillight.
