Video Transcript for Mighty Cord Wiring - Trailer Connectors - A10-4225VP Review

Today, we're going take a look at the Mighty Cord 25 foot long, wishbone, four way trailer wiring harness with the 36 inch long ground wire. This is a 25 foot long, split wishbone, four way trailer wiring harness that has four conductors and a 36 inch ground wire. Basically, the four way trailer end, which is a molded one piece end, is built right in. Each wire on this is a 20 gauge size wire. Now, this wishbone wire is a Y harness that will contain an extra tail light wire, makes wiring the trailer very quick and easy. What basically happens when you use this, because the brake signal is sent along the same wire as each turn signal, the tail light signal is the only one that needs to be run along both sides of the trailer. This Y harness or wishbone harness with the four way flat connector contains two separate tail light wires, the brown wires right here.

One is bundled with the left turn, which is the yellow, and one is bundled with the green wire, which is the right turn. When you go to wire this, it'll make wiring your trailer very quick and easy and simple to do. As they mentioned, you can see it has the 36 long separate white ground wire that you need to connect to a good, clear ground. That should do it for the review on the Might Cord 25 foot long, wishbone, four way trailer wiring harness with the 36 inch long ground wire.

Do you have a question about this Wiring?


  • 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...

  • What Does Some Trailer Wiring Have 2 Brown Tail Light Wires
  • Common 4-pole trailer wiring like # HM38138 uses one wire, the brown one, for the running lights on both sides of the trailer. Sometimes what is called a 'wishbone' harness is installed on the trailer and this simply uses two separate running light wires - brown with yellow for left and brown with green for right - to make it easier to connect to the trailer lights since that way no jumper wire will be needed to cross from one side to the other. Some examples of wishbone style 4-pole...

  • 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...

  • Installing Reverse Lights on Trailer Using 7-Way Connector and Wishbone 4-Way Wiring Harness
  • Using the Mighty Cord Wishbone 4-Way Flat Trailer Connector - Trailer End - 25' # A10-4225VP will give you the wiring for the tail lights on each side of your trailer giving you both the running light for each side and then the stop/turn function for each side. The ground wire will connect to your trailer frame on a bare metal to metal surface. Then when using the Mighty Cord 7-Way RV-Style Trailer Connector w/ Molded Cable - Trailer End - 10' Long # A10-7W10 or similar based on length,...

  • 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...

  • Recommended Universal Wiring Harness for Trailer and Vehicle
  • Yes, you are correct the # A10-4225VP is a 25 foot length of wishbone 4-way wiring for the trailer with a trailer connector. A good universal harness for your vehicle is the # 119190KIT. The cost's of each item are listed on each page. I have linked both to this page for your purchasing convenience.

  • Troubleshooting 4-Way Trailer Wiring Causing Blown Fuse Each Time Connected
  • Different trailers can have slight differences in materials, and wiring function. Since this trailer blows the fuse in your vehicle every time it is connected, it sounds like there is a short to ground somewhere on your trailer. This bad connection can be anywhere from the trailer connector back, since other trailers work fine with your SUV. I recommend using a battery to test the wiring functions of your trailer when not connected to your vehicle. You can then use a tester like...

  • 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...

  • Function of Brown Trailer Wires With Green and Yellow Tracers
  • If you are referring to wire colors on a trailer, then usually a brown wire is for running lights. If your trailer has two brown wires, one with a green tracer and one with a yellow tracer, then these would typically be the running light wires for the right and left sides of the trailer, respectively. Some trailer harnesses such as the 25-foot Mighty Cord # A10-4225VP are what is called a "wishbone" harness, which has two running light wires to make it easier to make the connections...

  • Replacement Wishbone Trailer Connector To Replace 6-wire Connector
  • Your trailer connector is considered a wishbone connector. A wishbone connector splits the running light circuit into two separate wires. Instead of a single brown wire carrying the running light circuit, you have a wire for running lights on the right side of the trailer and another wire for left side running lights. Then you have a wire carrying the left turn/brake light circuit, wire for right turn/brake light circuit and white wire for ground. Since your connector has 6 wires you probably...

  • Recommended Coupler for Custom Kayak Trailer
  • For your small kayak trailer, I recommend the Fulton Fas-Lok Coupler # F222000301. This will give you a 2 inch ball compatibility along with the ability to use a 2 inch square bar that you'd need to obtain locally to give you the length you need. That size will fit a standard 2 inch receiver tube if that is what is on your trailer. If you need a 2-1/2 inch bar compatibility, then I recommend the coupler # CT-3002-Z. For a 3 inch bar compatibility, I recommend the # CT-3003-Z coupler....
