Video Transcript for Wesbar Wiring - Wiring Adapters - 707250 Review

Today we're going to take a look at the Wesbar 18-inch long adapter, 7-way RV, to a 4-way, or 5-way flat. This adapter will convert the 7-way blade-style connector that's on your vehicle, for use with a 4-way or 5-way flat connector that's on your tow, via car or trailer. Overall length on this cord is 18 inches long, end-to-end, and again, this is the part that would plug into the 7-way blade-style connector. On this end, you can see, there's where a 5-way would plug right into that, and you can also use a 4-way. A 4-way, when you plug it in, you just use the ground, which is the exposed terminal, and then the three right next to it. The end one would only be used if it was a 5-way, because the end one would be for the reverse light circuit.

That should do it for the Wesbar 18-inch long adapter, 7-way RV, to 4-way or 5-way flat connector.

Items were exactly as described and the Adapter and oval trailer light (amber). I accidentally ordered the wrong size Trailer wheel center caps (ordered 15" and I needed 14") the staff (Madison) was very helpful and friendly and walked me through the exchange process. Love doing business with etrailer. 432805

The Wesbar Adapter - 7-Way RV to 4-Way or 5-Way Flat - 18" Long is excellent. The cable is thick, not flimsy. The end connectors are sturdy. It's a good product.

  • Recommended Simplest Conversion for Trailer 4-Way Flat to 5-Way for Surge Brake Lockout & Jeep 7-Way
    For your 2015 Jeep Grand Cherokee, the 7-way trailer connector is already a huge help. I recommend simply using the 7-Way to 5-Way/4-Way Trailer Adapter # 707250 or the # 707250. This will give you the 5-way that includes the reverse function to allow you to add the solenoid lockout to your surge coupler. Using a Reverse Lockout Solenoid for Demco Hydraulic Brake Actuators - Non-Bypass # DM11993 or the Titan # T4748800 will allow you to backup without the braking pressure to your...

  • Wesbar Adapter 7-Way To 4 or 5-Way Flat Adapter Compatibility With 2017 Chevy Silverado
    Yes, the Wesbar Adapter - 7-Way RV to 4-Way or 5-Way Flat - 18" Long # 707250 is compatible with your 2017 Chevy Silverado Z-71 with trailer package. This adapter will fit into the factory 7-way connector to allow you to use a 4-way flat trailer connection or a 5-way trailer connection.

  • Recommended 7-Way to 4-Way Wiring Adapter for 2015 VW Tiguan R-Line Package
    It sounds like you you have a standard 7-way trailer connector, so I recommend either the Pollak 7 Pole to 4 Way Connector Adapter # PK12716 or the Wesbar Adapter - 7-Way RV to 4-Way # 707250. If you happen to have a European 7-way, then you will want adapter # 118710.

  • Creating 7-Way Trailer Connection Adaptor for 13-Way European Bike Rack Lighing
    We do not have any European 13 way adapters to make your bike rack lights compatible so you will need to rewire it. So you would need to create a custom adapter using a 7-way connector and probably a junction box to protect an external converter box that you will need to separate the stop light from the turn signal for your 13 way bike rack wiring. For this conversion, I recommend the Vehicle to Vehicle Tail Light Converter # 118158 along with the Wesbar Adapter - 7-Way RV to 4-Way or...

  • Recommended 7-way to 4-way Flat Trailer Connector Adapter
    Yes, we have a few options for a 7 way to 4 way flat trailer connection. One option if you don't need an extension is the Hopkins Adapter 7 Pole to 4 Pole with Tester and Cover, # 47345. This adapter has an LED tester internally to allow you to check your vehicle side trailer wiring functions at the connection. If you need an extension adapter, I recommend the Wesbar Coiled Adapter - 7-Way RV to 4-Way or 5-Way flat # 787196 for an 8 foot option. For a much shorter extension adapter...

  • Recommended Wiring or Adapter for 7-Way Connector to 4-Way Utility Trailer Plug
    A trailer can be wired to connect to a 7-way without using all the functions. I recommend the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141 to give you a clean molded connector and then only connect the functions in the junction box needed for the trailer. Your other option is to use a basic adapter from 7-way to standard 4-way like # PK12716 or # 707250. When making electrical connections a little dielectric grease like # 11755 will help with the electrical...
