Video Transcript for Review of Wesbar Wiring - Trailer Connectors - W787274

Today we're going to take a look at the Wesbar 14' long, four-way flat connector with the jacketed cable for the trailer end. Now, this four-way flat connector provides a male plug for your trailer. It uses a jacketed cable to protect the wires against the elements. On this side, you can see I used the color-coded stripped wires to ensure a nice, simple installation. The specs on this again, the total length's 14'. The cable, the jacketed cable diameter is .40 of an inch.

The wire gauge to choose in this is 14 gauge wire. Now, the wire configuration on these colors, the yellow wire would be for your left turn and stop lights, green wire is right turn and stop lights, white wire is for your ground, and your brown wire is for your tail lights, license, side marker, and clearance lights.But that should do it for the review on the Wesbar 14' long, four-way flat connector with the jacketed cable for your trailer end.

I am very pleased with the wiring I received. It has a nice thick outer casing which should prove to be quite protective, particularly from the elements. I did add an additional shell I found on[line] which is a coated metal conduit. The etrailer wiring fit into it perfectly (with a little boost from a squirt of silicone). It's not that the etrailer wiring was bad - anything but - it's that we have particularly determined mice (we live in the country) who have eaten through wire coatings in the past, even thick ones. Together - unstoppable. This is the third time I have had to rewire that trailer (because of the mice) and hopefully the last. 799893

The Wesbar 4-Pole Flat connector w/Jacketed Cable has enough wire to reach the rear of most trailers so no wiring connectors are needed at the tongue of the trailer where most wiring problems occur. 489377

After years of using standard flat 4 wiring harnesses and breaking wires, I decided to look for a professional moulded plug and jacketed wire set. That is when I came across this product at etrailer. The product was packed well and arrived quickly. I will be replacing my current trailer wiring with this item on my trailer and getting a second product for a friend's trailer in the spring. 452616

  • 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.

  • Available Vehicle and Trailer Wiring Connectors
    I cannot recommend custom-fit trailer wiring for your vehicles without knowing their year, make, model and version but I can help you with basic 4-pole type connectors for both the vehicle and trailer. I linked pages for both types of connectors. For a trailer side 4-pole you can wire in to your trailer we have items like # W787274 and # 54000-026. For a vehicle side 4-pole we have # 18252 and # C58345 which includes a bracket. For a bracket only use # 18144. I also linked a helpful...

  • Wire Gauge and Jacket Diameter for Wesbar 4-Pole Flat Connector w/ Jacketed Cable, # W787274
    I used a wire gauge and some digital dial calipers to get the measurements that you need for Wesbar 4-Pole Flat Connector w/ Jacketed Cable, # W787274. The copper wire gauge using the gauge measurer fell between 14 and 16 for all wires so 16 gauge is what I would call it. The diameter of the jacketed wire is 0.4 inches measured with the dial calipers.

  • Availability of Protective Cover for Wesbar # W787274 Trailer End 4-Pole Connector
    We have exactly what you're looking for, part # W787301 which is compatible with the Wesbar # W787274 you mentioned.

  • How to Get Trailer Wiring From One Side of Running Light Circuit to Other Side of Trailer
    Since the Wesbar 4-Pole Flat Connector w/ Jacketed Cable # W787274 is 14 feet long and you need 13 feet to get to the taillights on each side of the trailer you'd have enough wire for each color aside from the brown wire. You'd want to run it to one side of the vehicle and then use a jumper wire like part # 12-1-1 to get the circuit to the other side. The # 12-1-1 is sold by the foot.

  • Recommendation for Higher Gauge Wiring to Use on Trailer
    I recommend taking a look at the Wesbar 4-Pole Flat Connector # W787274 for your trailer. This 4-Way flat, trailer-side connector includes 14 feet of jacketed, 14-gauge wires for easy installation. This thicker wire will definitely hold up better than the existing wiring on your trailer. If you just need jacketed wire and not the connector, you can use the Deka # DW04923-1. This 4-Wire, jacketed wiring uses 14-gauge wire and is sold by the foot, so you can order the exact length you...

  • Replacement 4-Pole Trailer Wiring Connectors and Harnesses for Harbor Freight Trailer
    Bargain-priced import trailers often use lower-grade parts that tend to wear out faster than better aftermarket products. This is as true for wiring items like your 4-pole harness as it is for other mechanical parts like bearings. We can help. For a replacement trailer-side 4-pole connector only that you can splice to your existing wiring you can use the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector # HM48192. If you prefer a connector with wiring we have many...

  • Will Wesbar 4-Pole Trailer Connector be Long Enough for 10 Foot Trailer
    The best way to know if the 14 foot Wesbar 4-Pole Trailer Connector # W787274 is long enough for you is to measure. Hook your trailer to your truck and measure from the truck's trailer connector back to one tail light. You'll need some slack in the harness for it to work. You can always add wire if you need to, or for making the jumper connection, using # DW04923-1, which is sold by the foot.

  • How to Test to Determine Function Carried on Trailer Wiring
    Often trailers will use the commonly-accepted wire colors for specific functions, such as a blue wire for trailer brake power, but there is no guarantee that a wire's color correctly tells you what it does. The surest way to know what a trailer wire does is to directly apply 12V power to it and see what function on the trailer is activated. In typical 4-pole trailer wiring a yellow wire will carry left-side stop and turn light signals. You can use your vehicle's battery (or a well-charged...

  • Wiring Guide for Installing Lights on Trailer with 5 Wires
    A trailer can have either 4-pole or 5-pole connectors and the number of actual wires can vary too. For instance, the part you referenced # 16-4B-1, is 4-pole wiring like what is included in a part like # W787274 which is a trailer-side 4-pole setup that carries stop, turn and tail light signals. There are also 5-pole connectors like # HM47910 that add one additional circuit that can be used for trailer brakes or another function. Then there are also wishbone style harnesses that have...

  • Heavy Gauge Trailer 4-Way Wiring, 16 Gauge
    The longest 4-way harness we offer that has all 16 gauge wire is the Wesbar Harness part # W787274 which is 14 feet long. For one that is 30 feet long that has a 16 gauge ground wire and 18 gauge signal wires you would want the part # W002230.

  • 16 Gauge Wiring Options for the Hopkins Replacement Endurance 4-Way Trailer Connector
    While it is possible this may work, I did contact Hopkins who confirmed this Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector # HM48192 is designed for use with 16 or 18-gauge, not the 14-gauge of the Wesbar 4-Pole Flat Connector w/ Jacketed Cable # W787274. They did not recommend this approach of stripping wires to make it fit. The Hopkins Endurance Quick-Fix Replacement is not a great long term solution but with the appropriate length of Deka Wire - Jacketed...

  • Wire Gauge of Wesbar 4-Pole Flat Connector With Jacketed Cable
    I verified with Wesbar that the 4-Pole Flat Connectors # W787274 for the 14 foot, # W787270 for the 10 foot, and # W787268 for the 8 foot are all 14 gauge wires.

  • Replacement Trailer Side 4-Pole Connector for Boat Trailer
    We do offer replacement trailer-side 4-pole wiring kits that you can use to replace the damaged one on your boat trailer. For a trailer-side 4-pole we offer various lengths, such as the 4-foot Wesbar # W787264, 8-foot harness # W787268 and 14-foot # W787274. The Hopkins part # HM48240 that you referenced is a similar 20-foot harness. This features a wishbone construction, which means dual running light wires so that there is one for each side of the trailer. We also have a 35-foot long...

  • Trailer Lights Not Working After Launching Boat Trailer Into Water
    It sounds to me like you may have shorted out a wire somewhere along on the trailer's wiring harness. To test this, I recommend using a circuit tester like part # 40376. Have a friend sit in the vehicle and apply the brakes and turn signals while you test the wires just before the taillights. If power is reaching the tail light but still not working, you will first want to ensure the connections at the back of the taillights are secure and corrosion free. If no problems are present, you...
