Reduce the frustration associated with troubleshooting trailer wiring problems with this lighted 5-way connector. It has built-in LED lights that help you determine quickly and easily if the issue is with your tow vehicle or your trailer. Just plug the connector into the 5-way flat on your vehicle. No need for separate testing tools. Then activate each function on your vehicle and a red light will come on if power for that function is being received by the connector. If there is power going into the connector for all of the functions, then you know that the problem is on the trailer end and you will need to check your trailer's wiring. Each function except for ground is represented by a separate light and the functions are labeled for easy identification.

Great Product, better than the factory plug that came on my boat trailer. 848280

Provided a necessary fix after (I suspect) some neighborhood kids cut the wiring near the tongue of my boat trailer. I used heat shrink tubing to ensure a water tight connection. 686555

Added backup lights on a small trailer so needed a SAE 5 flat plug. Works well. Also fits to a normal 4 flat connector on cables of vehicles without the 5th connection The trailer side 5th pin just overhangs the side of the vehicle cable. However, this won’t plug into flat 4 vehicles where the recepacle is recessed, as the fifth conductor would hit the vehicle receptacle. 542325

  • Replacement 5-Way Connector for Ranger Boat Trailer
    For a replacement 5-way we have the Hopkins 5-Way part # HM47913 which will work great. This even has circuit testers for each wire so that you can easily make sure everything is working properly. Wiring configuration on # HM47913: Green: right turn signal (RT), you'll run this to where the green wire was connected. Yellow: left turn signal (LT), to where yellow wire was connected. White: ground, to white wire connection. Brown: tail light and side marker lights (TM), to both the...

  • 5-Way Trailer Wiring Connector Replacement for Trailer Where 5-Way Fell Off
    So the white wires are the ground wires most likely, the brown wires are the running light circuit most likely, the yellow is left turn/stop, the green is right turn/stop and the blue wire should be reverse lockout or brake output depending on your trailer's brake style. For a new 5-way you would want the part # HM47913 and you would wire it by color to your trailer's wires as they colors appear to be the same.

  • Testing Trailer Brakes on 1973 Horse Trailer
    If your trailer does indeed have electric brakes and you want them to actuate, you will need a brake controller to activate them when the vehicle brakes are applied. We offer a large selection of brake controllers, I would recommend the Tekonsha Prodigy P2, part # 90885. The P2 is a proportional controller, which means that when properly adjusted the trailer and the vehicle will brake in tandem which saves wear and tear on both the vehicle and trailer braking systems. To install the...

  • Is there an Adapter for a 6-Way Square Jayco Trailer Connector
    On the 6-Way square connectors # 37995 they are more of a generic type of 6-Way square. The one in your picture looks like the infamous Jayco 6-Way like what is found on adapter # 30104. But you need the opposite end from what is on this adapter. What you will need to do is remove the 6-Way connector you have and wire in something common in its place. Since you already have # 37995 you could use it, or at least the half that you need. Then wire the other end to the connector type that...

  • Longer 5-Way Trailer Wiring Connector with Lead
    The longest 5-way connector for a trailer that has built in circuit testers is the part # HM47913 that you referenced. For a 48 inch 5-way and lead we have the part # 20017 but it does not have the circuit testers. We do have a 5-way tester too that you could use with this as part # 20115.

  • Installation of Electric Lockout Solenoid for Brake Actuating Coupler
    For surge brake actuators, the solenoid like the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800 will allow you to bypass your brake actuator when backing up. The unit screws into the back of your master cylinder and then the brake line connects to the other end. One wire of this electric lockout solenoid will connect to the trailer frame as a ground and the other will connect to the reverse light function wire coming from your vehicle. You can connect...

  • Best Trailer Hitch for a 2018 Highland Ridge Open Range 5th Wheel Trailer
    The trailer hitch I recommend you use on the back of your 2018 Highland Ridge Open Range Light LF291RLS to mount bikes or pull a trailer is the Adjustable Width Trailer Hitch Receiver part # 13703. The Adjustable Width Trailer Hitch Receiver is the most popular trailer hitch we have for trailers because it fits so many different types and allows for the receiver tube to be placed in the best position to ensure you don't have any clearance issues with a bike rack for example. It offers easy...

  • Titan Brake Actuator Compatibility With Electric Lockout For Backing Up Without Engaging Brakes
    You can add an electric lockout to a Titan Zinc-Plated Brake Actuator # T43397007K. To do so, you will want the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800. You can then use the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036 to connect your reverse light function to send signal to your trailer side 5-way when you shift your vehicle into reverse. This adapter along with the Hopkins 5-Way Flat Trailer Connector w/ LED Test Lights -...

  • Replacing a 5-Way Trailer Connector that Has 10 Wires Ran to It
    There is a very easy solution for you! It does not have 10 wires but is exactly what we use anytime we change these out. The Hopkins 5-Way Flat Trailer Connector w/ LED Test Lights part # HM47913 can be spliced directly to your current wiring color for color. Basically use the Deka Heat Shrink Butt Connector part # DW05745-5 and splice the two white wires to the single white on the plug. Do this for the 4 remaining colors and you are set. Use a heat gun or other heat source to shrink down...

  • Replacing 4-Way Female to 5-Way Male Wiring Loop
    I do have a solution for you, however the female 4-Way to male 5-Way loop that you have is no longer available. Instead of using another adapter like this one your best option will be to actually cut off the 4-Way connector from the trailer and splice in a 5-Way like the Hopkins # HM47913 in its place. The blue wire from the 5-Way will go to the blue wire that you mentioned coming from the actuator. With this in place on the trailer you will be able to connect directly to the 5-Way on the...

  • Troubleshooting New Wiring Harness On Trailer For Reverse Lights
    In order to get the reverse lights to work on your trailer you will need a 5-way on your vehicle and also on your trailer. It sounds like you have wired the 4-way up but now you need the reverse lights. I recommend removing the 4-way connectors on both the towing vehicle and on your trailer and installing 5-way connectors. For the trailer side I recommend part # HM47913. You would attach the white, yellow(or light green), green, and brown wires to the same color on your trailer and...

  • Replacement Trailer Connector with 8 Wires for a Boat Trailer
    A 4-flat trailer connector is responsible for carrying four functions which are usually brake, left turn, right turn, and tail lights. I am not familiar with a 4-way trailer connector that uses 8 wires as I do not see what the other wires could be for. The best way to determine the correct replacement would be to test each of the wires for function with a circuit tester and then replace the connector with the one that has the slots for the functions you need. It may be that instead of splicing...
