Video Transcript for Wesbar Wiring - Trailer Connectors - 002402 Review

Speaker 1: Today we're taking a look at the Wesbar four-pole flat connector. This connector provides simple efficient method for rewiring your trailer, with a four-way flat trailer end connector.So, this would hardwire into your trailer's wiring, and then it would provide the plug, which would plug into the tow vehicle to send the signals back to the trailer.It's a nice design. When it comes to the wiring, you actually have two brown wires on the unit. So, you have a singular white wire, and then you have two brown. One brown runs with the green, the other brown runs with the yellow. So, this gives it the wishbone design.

That way you can run your stop, and turn, and tail signals down each side of your trailer.The connector has a easy grip design on the sides, and it's easy to identify, because the wires are labeled. So, your white wire's your ground wire, and then on the actual brown and green wire, the green says right turn, so that would be right turn and brake, and then brown is taillights, and then yellow is your left turn and brake, or driver's side, and then brown that runs with that is for the taillights.That's gonna do it for today's look at the Wesbar four-pole flat connector.

I had difficulty finding the correct 5 wire flat plug locally at all the name auto stores. Preferred to buy locally but resorted to the web and found etrailer.com and talked to Carla. She knew exactly what I needed and got my order going asap. She was awesome! I have not yet did my wiring as it has been really cold but plan on it before spring. Thanks Carla 597622

I shopped for this part at 6 different auto parts stores around my home. I was amazed that no one carried a trailer wiring harness with 4 prongs and 5 wire configuration. After surfing the net for this part, again, I was amazed at what some distributors were charging for such a simple connector. When I came across etrailer.com I was elated that they actually had the part for a very reasonable price and a small shipping fee comparable to what was actually being shipped. Took four days to get here, plenty of time to get my trailer rewired and ready for the farm on Sunday. Etrailer is at the top of my list from now on. The plug-in part is very well made and heftier compared to what I replaced. BTW I ordered 2 so I have a spare. 707243

Wow! Super impressed with this company. The item ordered was just what I needed and delivery was prompt. Loved how I could track the order easily. I was so happy to receive the wiring harness in time to use with my boat trailer to get my boat out of the water for the impending hurricane. I will definitely be ordering from this site again. 854463

The product was great, delivery was just as expected and advertised, and it worked perfectly. The connector I had on my trailer got sheared off at some point and I couldn't find it. This was a great replacement. It was easy to reconnect since the wires were color coded like those on my trailer. Thank you!!! 847612

I’m totally happy with this company, I needed this part before I could travel and was worried I wouldn’t get it in time. It came a day earlier then planned and I wired it on the trailer myself. Girls can do anything! This part was not available in any of the stores near where I lived so I was very happy to find it online. A auto place near by told me 80 dollars an hour , that it would take at least 3 hours to fix it. I said no way to myself, when the part came I installed it in 20 minutes. Thank you etrailer ! 735921

Ask the Experts about this Wesbar Wiring

  • Replacement Wishbone Style 4-Way Trailer End Plug
    Thanks for that photo and what you have is a wishbone style wiring harness, although the colors are inconsequential for a harness because there isn't a standard wiring code that is color-for-color. You can replace your harness with the Wesbar Wishbone Wiring Harness with 4-Pole Flat Trailer Connector - Trailer End # 002402 but you will need to wire it by function. This means you'll have to apply 12 volts to your wires via a battery to determine the function of the wires so you can connect...

  • Installing New 4 Way Connector on Trailer with Yellow, Green, Yellow/Brown and Green/Brown Wires
    It sounds like your trailer had a wishbone style wiring harness. A wishbone harness splits the running light circuit at the connector so you do not have to run a jumper from one side of the trailer to the other side. To replace the plug you're going to be best served by using a wishbone harness like the Wesbar Wishbone Wiring Harness with 4-Pole Flat Trailer Connector - Trailer End - 18" Long # 002402- you can still use a regular 4 way, but it will be more work.

  • Troubleshooting 4-Way Trailer Wiring with 5 Wires That Isnt Working Correctly
    It sounds like your new trailer wiring is designed to connect to a 4-way wishbone connector where there are two brown wires for the running lights. The yellow/brown wire is for the running lights on the left side and the green/brown wire is for the running lights on the right side. This makes it so you don't have to use a jumper wire to go from one side to the other. What you've tried to do should work; connecting the two brown wires to the single brown wire on the connector.

  • How to Convert a Wishbone 5-Way to a Wishbone 4-Way Trailer Connector
    It looks like you have a 5-way wishbone wiring harness. I cannot say for certain but my guess would be the that the following are true: White Wire = Ground Green/Brown = Right Running Light Yellow/Brown = Left Running Light Yellow = Left Turn/Stop Light Green = Right Turn/Stop Light Red = Reverse Light/Brake Output In order to test this you will need to apply 12 volt power to each wire and see which circuit it activates. For a 4-way wiring harness to replace this you are going...

  • Replacement Trailer 4-Way Recommendation for 4-Way with 6 Wires Ran to It
    You'd need a wishbone style 4-way replacement like the Wesbar part # 002402 which you'd wire in color for color. The only wire you'd need to run down into a single wire is the white wire since you have a wishboned ground circuit as well as the Wesbar does not have that.

  • Wesbar Trailer Side 4-Way Recommendation with Short Wire Leads
    The Wesbar trailer end 4-way we offer that has the shortest amount of wire lead is the part # 002402 which has an 18 inch wire lead.

  • Recommended Lights for Aluminum Cargo Carrier on a 2012 Mercedes-Benz ML550
    What I recommend installing is the Optronics LED Trailer Tail Light # STL78RB on either side of your cargo carrier. Then for your connector use the Wesbar Wishbone Wiring Harness # 002402 with the Hopkins Adapter # 47345 so it is compatible with the 7-Way on your 2012 Mercedes-Benz ML550. The wiring configuration for the Wesbar wishbone is as follows: White - ground wire Yellow - left turn/brake light Green - right turn/brake light Brown - tail lights For extra wiring use the Bonded...

  • Electric Brakes And Lighting For The Roadmaster Tow Dolly RM3477
    The great benefit to using a tow dolly is that it eliminates the need for installing a base plate, installing difficult wiring, or purchasing an expensive supplemental braking system. Also the Roadmaster Tow Dolly with Electric Brakes # RM-2050-1 is fully wired for brake lights and turn signals. The Tow Dolly comes with bare wires so you would need to purchase a 4-way # 002402 or 7-way connector like # 54-67-525 seperately to match up to your tow vehicle's wiring. Included are video...

  • How to Make 4-Way to 12 Volt Power Outlet
    Our best solution for that would be the part # 329-GC018 which is a cigarette lighter style of 12 volt connector that you could wire to the brown and white wires of a 4-way like # 002402. The brown would go to the red and the black to the white.
