Just rewired a cargo trailer I bought that the lights were always going out. Found 20 butt connectors the guy used no wonder they worked off & on. Now with two new tail lights & new wiring with a straight connection everything works like it should. Everything I have bought from etrailer has been good quality & fast shipping. Thanks 715875

It's a simple item but try to find it somewhere else as a stand alone product. I've used etrailer before with great results and this was no exception. Let's be honest, if you've been to the site once, you're coming back! I have a 5 x 12 utility trailer that has good lights but the wiring was a disaster. The harness connector had been patched and there were at least 5 splices throughout the lines. It was nice to lay out the new harness, make the light connections, tack everything up and out of harms way (there's an idea) and my lights work like new. I like the ground fastens under the jack bolt. Saves drilling a screw in (see the baby hole?) Good to feel safe on the road again. As easy and inexpensive as it was, I don't know why I waited so long. 539599

  • Using the AutowBrake Brake Controller with a 1999 Toyota 4Runner and a 1997 Toyota Previa
    Installing the Autowbrake brake controller, part # 3430001, doesn't actually requrie you to make any changes to the 4-way connectors on your vehicles. All it needs to function is to be wired to the proper wires on the trailer and a constant power source. If you want, you can wire the Autowbrake's power wire (the black wire) to the trailer's running lights and then it will have power as long as you tow with your lights always on. The downside to this is you will then always be drawing...

  • Ways to Install New 4-Pole Trailer Connector
    Four flat trailer wiring, also called 4-pole wiring, uses four wires and pins configured as shown in the linked photo of a trailer side 4-pole connector. The one pin that is different from the other three (on both trailer and vehicle side connectors) will be the ground pin and this usually has a WHITE wire that will ground to a clean bare metal spot the trailer frame with a ring terminal. The next pin is for the running light circuit and this typically uses a brown wire to activate...

  • 4-Pole Wishbone Harness for Running Light Connection
    Connecting the brown running light wire in standard 4-pole wiring to both tail lights will require a jumper wire from one side of the trailer to the other, or you can install what's called a wishbone harness that has dual brown running light wires, one for each side of the trailer. We have several of these trailer-side 4-pole wishbones, such as 40-foot # A40W42B, 35-foot # A35W42B, 25-foot # A10-4225VP and 20-foot # A20WB. I do recommend using a wishbone harness instead of a spliced...

  • Recommended Trailer Wiring for 5x10 Trailer with 4-Way Trailer Connector
    If you have a 4-way trailer connector like # 118418 then I recommend using a wishbone harness to wire your trailer. The 20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground # A20WB is my recommendation for your wiring because it will allow you to run 2 wired to each side. You will run the brown and yellow to the driver's side, and the other brown and green wire to the passenger side. The white wire will get connected to the trailer frame as a ground. The brown wires on each...

  • Parts Needed To Re-Wire Yakima Rock and Roll Trailer
    Part # Y8880203 and # 8880161 would be the wiring for the tongue while part # 8880162 would be needed for the rear lights. The balance of the wiring is run inside the framework of the Rack and Roll trailer. Since you said you are replacing all of the wiring you may want to use a wire harness like part # A20WB to re-wire your trailer. This harness gives you the 4-way connector at the front of the trailer and also the wiring to run down each side of the trailer for tail lights and running...

  • Replacement 4-Pole Trailer Connector for Utility Trailer with 5-Wire Wishbone Wiring Setup
    When a 4-pole (4-pin) flat trailer connector actually has 5 wires this simply means it is a 'wishbone' style connector with dual running light wires. These dual wires just make it easier to connect to the running lights on both sides of the trailer. Examples of such items are # A35W42B, # A20WB and # A10-4225VP. If your trailer wiring is still okay and you just need a new 4-pole plug to re-connect the leads from the trailer you can use Hopkins Endurance Quick-Fix Replacement 4-Way Flat...

  • Why Does 4-Pin Trailer Wiring Have 5 Wires
    Your 4-pin/5-wire wiring harness is what is called a "wishbone" type which simply means that there are two separate running light wires, one brown and one pink. This allows a separate running light wire for each side of the trailer which saves you having to run a jumper wire from one side of the trailer to the other. We offer lots of wiring items just like this, such as # A35W42B, # A20WB and # A10-4225VP, which happen to use two brown wires instead of one brown and one pink. The functions...

  • How to Extend Short Ground Wire on 4-Pole Wishbone Harness
    Wishbone 4-pole harnesses like # A35W42B, # A20WB, # W002230 and # A10-4225VP usually do have a short ground wire because most trailer frames are steel and they conduct well enough that a ground wire attached near the tongue will provide sufficient ground even for lights mounted all the way at the back of the trailer. On the other hand if you have an aluminum frame trailer that does NOT conduct electricity nearly as well as a steel frame then you might need to extend that 2- or 3-foot...

  • Can 12 Guage Wire Connect to 20 Gauge Wire With Butt Connectors
    When you have to go from a much thinner gauge wire to a thicker gauge wire with a butt connector you want to use the bigger size connector like # DW05745-10 which fits 10 to 12 gauge but the trick to getting the thinner gauge wire to fit well is to strip off 3 times as much insulation than you'd normally need and fold the core of the wire a couple times so that it ends up being thick enough for the butt connector to grab it.

  • Replacement Wishbone Connector for Damaged 4-Way on Trailer
    What you have that got damaged is a wishbone harness, and the Hopkins Endurance Quick-Fix 4-Way Connector # HM48192 will work, but you would need to combine the two running light wires and turn it into one wire. Or you could simply get a new wishbone 4-way # A20WB, cut off the connector and use butt connectors # DW05743-5 to combine the wiring. I've added links to video reviews of these parts for you to take a look at.

  • How Does Wishbone 4-Way Wire to Trailer's 4-Way Wiring that has 7 Wires
    The two white wires are the ground circuit which would run to the white wire of the # A20WB, the black wire has to be the right turn/stop signal although that color is typically solid green. The brown is a running light circuit that runs to clearance lights on the trailer, the yellow brown runs to the taillight assembly for the running light circuit, and green brown is the left turn/stop circuit. All of these run to either of the brown wires of the 4-way, and then the yellow is the left...

  • Wiring a 2011 Victory Motorcycle and Trailer for Towing
    For simplicity, I would recommend wiring the motorcycle trailer as a vehicle trailer would be. A powered converter wiring kit, like part # 119179KIT, would be connected to the motorcycle, which would provide a 4-pole trailer connector. The converter combines the brake lamp and the directional signal onto one circuit. The 4-pole connector utilizes four circuits, the white wire which is the ground, the green wire carries the right turn and brake light combined on one circuit, the yellow...

  • Can Euro 7-Pin be Replaced by American 4-Way?
    Sure, you can cut off the Euro 7-pin and add an American-style 4-way. I recommend using the Wishbone Wiring Harness # A20WB, which actually has five wires; it splits the running light wires so you do not have to run a jumper wire from tail light to tail light. You will need to do some splicing and you can use the accompanying diagram of a Euro 7-pin to see how they are typically wired. I recommend using butt connectors # DW05743-10 to connect the 20 gauge wires of the harness.

    It sounds like you are trying to say that you want to be able to tow your motorcycle tent camping trailer with both your motorcycle and your Hyundai Santa Fe.

You can simply use electrical tape like # DW04367 to connect the new wires to the old wires with a tight wrap to give you the connection to pull the old wire from tail light end allowing the new wire to pull from the coupler end through the metal tube into position.

  • Trailer Light Kit for a 10 Foot Trailer
    Legally a trailer only needs right and left turn signals, brake lights, and running lights. The license plate light will be tied into the running light circuit. On a trailer, the turn signals and brake lights are on the same circuit on each side. So the minimum you will need is 4-wire bonded wire such as # 16-4B-1 that you have referenced. For a trailer side 4-Way you can use # A20WB and you would not need the wire by itself. This is a 20 foot length and the running light circuit is...

  • 4-Way Trailer Wiring Harness has 5 Wires Coming Out of It
    It sounds like you have a wishbone harness. A wishbone harness has 4 pins like a regular 4-Way but where the wires come out the running light circuit is split so you do not have to run a jumper wire between tail lights. You cannot always go by color. If the wire that is split is right next to the ground pin (covered pin) then this is what you have, a split running light wishbone harness like # A20WB.

    It sounds like your problem may be limited to just one circuit - the wire that carries the right turn signal and brake light. To begin testing, I recommend checking the vehicle side and trailer side connectors for any signs of corrosion or damage and repair as needed. If the connectors look fine, I would test the vehicle side trailer connector with a circuit tester, like part # 40376, to make sure the vehicle is sending power to the trailer (see video).

    It sounds like your trailer has a special type of 4-pole connector called a wishbone harness, such as 20-foot # A20WB or 35-foot # A35W42B. These wishbone harnesses simply use two brown running light wires to make it easier to wire your trailer's lights.

    There are any number of reasons that you are not getting power on the green and yellow wires.

Use a circuit tester like # 40376 if needed to test the 4-Way end on the vehicle. If the power is not getting to the 4-Way that means the problem is on the vehicle side.
