Video Transcript for Wesbar Wiring - Trailer Connectors - 002220 Review

Today, we are going to be taking a look at Part Number 00220. This is the West Bar 4 Way Flat Trailer Wiring Harness. It is going to have the wishbone style. What that means is coming out of the back of the housing here on the plug, we are actually going to have 5 wires so it's going to double up on the brown wire which is going to be the tail light function so the brown wire, we have one that runs with the yellow wire and we have one that runs with the green wire. That is where we get that wish bone design from. Then we are going to have the four pull flat trailer and connector right here. It has got a nice grip design.

Male end, again this is the trailer end, 4 way flat connector. The unit is going to be color coded for simple installation. The overall length is going to measure 20 feet long so you are going to have a lot of wiring to re-wire your trailer. Your ground is only going to measure 3 feet long. Real quick, I also want to point out that your white wire is going to be gauge 16 wire and then your other wires are all going to be gauge 18.

The green wire is going to be for your right turning brake. Brown is going to be tail light. Yellow is going to be for left turn brake and then the white wire is going to be your ground wire. Here on the end of each wire, it's already going to be stripped back. It just has a nice protective end cap. All you have got to do is pull that off.

That is going to expose the strip portion. That way, it is ready for installation. You can also trim this to fit your particular application. Very easy to cut. Just get some wire cutters and you can cut right through this stuff and trim to fit whatever your application is. That is going to do it for our review of Part Number 002220..

Wanted to replace my broken plug with something close to the original that was on my trailer to be sure all my lights worked correctly without having to do a lot of extra work and modifications. Found the exact plug on- line through you guys and it was a matter of cutting it to the right length I wanted and splicing them together. Everything worked perfectly. Oh yeah. The order to delivery time was excellent. Part actually got here sooner than was told. Great product and great company to work with. 567846

I ordered the wiring package for my 2001 Toyota Tundra truck. It had never been wired for a trailer. I was afraid to use my trailer at night for "no lights" so I decided to wire the truck so that my trailer would have lights at night. I have never done anything like this before! I watched a video on how to wire the truck and followed the easy instructions included with the wiring package which was included with the product. I also ordered the reciprocal plug for my trailer. I could not believe how easy it was install this product in the truck and the trailer. After I finished, it took about an hour, it worked great the first time. I was really impressed with this product from etrailer! Thank you etrailer. You saved me a lot of money from buying this same product from Toyota and the labor also for installing this product! 468439

I'm so glad I don't have to spend an arm and a leg to rewire and get new taillights for my old utility trailer. Etrailer has low cost, but good quality parts that will make the job quick and easy to get my trailer operational again. They even have instructional videos to help with making repairs if you need them. Thank you so much, etrailer! 219681

Ask the Experts about this Wesbar Wiring

Do you have a question about this Wiring?


  • Trailer Lighting/Wiring Kit for Snowmobile Trailer
  • Standard 4-pole trailer wiring uses flat-style connectors, like part # W787268 which is a trailer-side connector and part # HM48044 which is the mating vehicle side connector. On these items and on the 16-gauge bonded 4-pole wire # 16-4B-1 you referenced in your question the usual pin/function assignments are the same. These are as shown in the linked photo and in the article on trailer wiring that is included for you. The one pin that is not like the others will be the GROUND pin which...

  • Circuits and Functions Supported by 4-Pole Flat Trailer Wiring
  • In 4-pole flat type trailer wiring such as part # 002220 the tail light circuit (also known as the running light circuit) is usually assigned to the brown wire which connects to the pin next to the ground pin. You can see this in the photo I linked for you. This type of wiring format does not support an additional circuit for +12V auxiliary power as might be needed to top off a trailer-mounted battery or to operate a jack or winch on the trailer. Other wiring formats with additional...

  • Installing Brown Running Light Wire on Trailer
  • When testing the brown wire on your trailer, all of the tail lights on the trailer should be activated. Since you are using a standard 4-wire harness on the trailer, you will need to make sure that you are using jumper wires to provide running light functions for both sides of the trailer. The single brown wire will go back from the 4-Way connector on one side of the trailer, but will then need to be fed to the lights on the other side as well. I have attached a wiring diagram that clarifies...

  • How to Attach a Trailer with a 3-Way Connector to a Vehicle with a 7-Way Connector
  • A 3-way trailer connector is extremely rare and they really do not make any sort of adapter that will allow you to use this trailer connector with a 7-way connector. The only option that I have for you would be to replace the 3-way trailer connector with a 4-way trailer wiring harness and then use a 4 to 7-way trailer connector adapter. It is required by law in most states that your trailer has turn, brake, and running lights therefore if your current trailer's lights do not have these...

  • Availability of Just 4-Way Connectors
  • What harness are you looking for? Like a 4-way that comes on part # 002220? We have the part # 48195 as well or the part # 9653P that comes with both sides plus wiring if needed. You would just cut the middle of the wiring and would have wire for both sides.

  • Replacement 4-Way Solution for Trailer that Has 2 Wires Ran to Each 4-Way Pin
  • Sounds like your 4-way has two wires ran for each pin. This can be wired to a 4-way that has a single wire for each pin. You would just have to run the pair of wires for each circuit to the single wire of the new 4-way. The part # 002220 that you referenced could work but it would be a bit long at 20 feet. You would just need to cut down the length of the wires.

  • How To Connect Vehicle 4-Flat Connector To Loose Trailer Wires
  • It sounds like your truck has a 4-way flat trailer connector with yellow, green, brown and white wires (see picture), which is pretty standard. It also sounds like your trailer has 5 loose wires that you are trying to connect to a trailer side 4-way flat connector similar to part # W787264. If this is the case, then it sounds like your trailer came with a wishbone style wiring harness meaning you have two running light wires (brown wires) for each side of the trailer, the left turn...

  • Replacement Wiring Needed for a 6 x 10 foot Trailer
  • We don't actually manufacture our wiring harnesses, but we do have some options available for you. You can use the Wesbar Wiring Harness # 002220 to replace the wiring on your 6 x 10 aluminum trailer. To complete the installation you will only need a Ring Terminal # DW05702-1 and Butt Connectors, part # DW05744-5 for 5 or part # DW05744-10 for 10. Just simply splice in the lights that you have into the wiring. If you don't already have lights then you can use the Trailer Light...
