Hopkins Wiring - HM47900

  • Trailer Connectors
  • Vehicle End Connector
  • 5 Flat
  • Plug and Lead
  • 0 - 5 Feet Long
  • Hopkins

Five-wire design is perfect for newer boat trailers that have hydraulic brakes. Easy-pull connector housing makes disconnecting a snap and includes built-in mounting holes and a protective dust cover.


Features:

  • 5-Wire design common on boat trailers with hydraulic brakes
    • Provides backup function to release surge brakes
    • Fits most 4-way connectors
  • Easy-pull, ergonomic grip on connector makes disconnecting a snap
  • Heavy-duty connector housing has built-in mounting holes
  • Durable, molded dust cover provides superior protection for terminals
    • Tin-plated terminals resist corrosion
  • Nylon sleeve and heat-shrink tubing protect wires
  • Terminal grease packet included


Specs:

  • Connector: 5-way flat
  • Wire length: 48"
  • Wire gauge: 16
  • 3-Year warranty


The 5-way flat connector is found on most newer boat trailers that have hydraulic brakes. The fifth wire in this model ties into the reverse lights on your vehicle so that a signal can be sent to your hydraulic brake actuator to disengage whenever the tow vehicle is put into reverse. To use this function, your actuator must have an electric reverse lockout with solenoid.


The 5-way design will also work with small utility trailers that have electric brakes. For this type of application, the fifth wire will need to be wired to correspond with your in-cab, electric brake controller.

Connector and wire harness well made - connector designed such that it can be mounted and harness has added protection for wires. Would like to have marine grade wire since I do mostly saltwater fishing. I mounted the connector on a piece of 1.5" square galvanized tubing painted black.

Still 5 Stars! E-trailer always has what I need!

by:

Delivery was faster than I expected. I bought a converter with the appropriate adapters to go from a 4 wire vehicle to a trailer with turn signals separate from the brakes. I haven't done my final assembly yet, but I did take a few minutes to twist the wires together to make sure everything was going to work like it was supposed to. Instructions were clear, wires & converter were clearly labeled & preliminary hook up took less than 10 minutes.

Not installed yet due to weather & travel. Prefer to 5 pin adapter kit. Like extra cable / wire length to connect to Jeep wire harness so all connections are in a protected space. Heavy duty and like dust cap.

This connector is built to last. A big step up from most flat 4 or 5 wire in quality. With it's secure fitting dust/dirt cover I have no worries that the terminals will stay clean and always make a good connection . The 3 year warranty is a plus also.

Ask the Experts about this Hopkins Wiring

  • Where Does Fifth Pin of Trailer 5-Way Run to Activate Reverse Lock Out Solenoid
    Sounds like you are trying to activate a reverse lock out solenoid on a surge brake trailer so that it can back up freely. The fifth pin that is the furthest from the jacketed ground pin is the fifth circuit to use. This circuit would need to tap into the reverse light circuit of your tow vehicle. I attached an install video for the 5-way adapter part # 47515 that shows this process on a 2014 GMC Acadia.

  • Wiring Replacement 5-Pole Trailer Connector on 2012 Ranger Trailer
    You can use a standard 5-pole trailer connector, you'll just need to wire it a certain way. The # HM47900 you referenced is the vehicle side connector, you need the trailer side connector like part # HM47910, which would wire as shown in the provided photo. The red wire you mention is for the reverse lockout on the trailer coupler, and is tied in with the reverse lamp circuit of the vehicle. Both brown wires would connect to the brown wire of the trailer connector. The yellow and green...

  • Does 4-Way Trailer Wiring Harness Have Reverse Light Feature
    I can certainly help you with that. Since the Curt T-Connector Vehicle Wiring Harness, part # C55384 is a 4-way connector the four functions will be Yellow for the left turn and brake, Green is for right turn and brake, Brown is for running lights, and the White is the ground wire that gets attached to a clean metal surface. For the reverse light function you will need a 5-way trailer connector and you can use the fifth wire to attach to the reverse light circuit on your vehicle....

    If your 2008 Honda Ridgeline has a factory trailer wiring harness, check the owners manual for any fuses and relays related to the tow package wiring that may need to be replaced. If everything checks out or if you have an aftermarket wiring harness like # 118400 then use a circuit tester like # 40376 if needed to test the pins on the connector. If the pins on the connector do not show the proper signals then you know there is a wiring issue with the Ridgeline wiring that needs to be...

    Since we do not carry Frontier Gear headache racks, I do not have wiring diagrams or other installation instructions pertaining to this product. However, I can give some insight and do my best to point you in the right direction.

  • Troubleshooting Trailer Running Lights Not Working, Turn Signals and Brake Lights Do Work
    The white wire is probably the ground wire and it needs to be connected to a clean, corrosion free bare metal surface on the trailer frame. Without a good ground, some or all of the trailer lights will not work or work properly. You can also check the grounds for each tail light. Trailer tail lights usually ground through the mounting studs and they, too, will need to be attached to a clean corrosion free bare metal surface. There is not always a universal wiring color code that everyone...

  • 7-Way to 5-Way Adapter for Boat Trailer with Electric Reverse Lockout
    Yes, there are 7-Way to 5-Way adapters that you can use. If you want one that is just a 7-Way to 5-Way then # A75TB is a great option. I have linked a video review for you. If you want something that is a little more versatile we have # 37385 which is a 7-Way to 4- and 5-Way. I have linked a video review of this adapter as well.

  • Can Blue Wire of Hopkins Endurance 5-Way Flat Trailer Connector HM47900 be Used for Reverse Circuit
    The blue wire of the # HM47900 can be used for basically any circuit. Typically for 5-ways like this the reverse light circuit is the most common circuit ran to the 5th wire. So this would work well for your application.

    We do offer any plug-and-play trailer wiring harness for the Kawasaki Vulcan Nomad.

  • Locating Reverse Light Circuit on 2001 Dodge Ram 1500
    I do not have any information that is specific to your 2001 Ram, but I can certainly help you through the process. The easiest way to do this is to access the rear of one of your tail light assemblies, as if you were replacing a burned out bulb. Once you look at the rear of the assembly, it should be immediately evident which wire feeds the reverse light (clear bulb). You would tap the wire with the blue stripe into that circuit, using a butt connector like part # DW05714. Be sure to...

  • Installing 5-Way Trailer Connector on 2011 Ford Explorer to Control Reverse Lockout on Boat Trailer
    If you already have a trailer wiring harness and 4 to 5-Way adapter like # 20036 then the easiest way to get to the reverse light circuit is to gain access to the wiring behind the reverse lights. This can be difficult if the reverse lights are on the hatch. If they are then they also have to run out from the hatch and into the body at some point, most likely near the top where the hatch hinges. If you keep following it you should be able to find a good place to tap into the reverse light...

  • Creating a 6-Way Round to 5-Way Flat Trailer Wiring Adapter
    We do not carry a 6-way to 5-way adapter, so I recommend making one using the Hopkins Trailer Connector Adapter - 6-Pole Round to 6-Pole Square # HM47415 and removing the 6-pole square to replace with the Hopkins Endurance 5-Way Flat Trailer Connector - Vehicle End - Ergonomic Design # HM47900. You won't use the 12V feature so I recommend removing that wire from the 6-way so it doesn't draw any power. I've attached a wiring article to help with the connections.

  • Using Front Hitch To Move Trailer With Hydraulic Surge Brakes
    If you have a manual lockout, you will be able to use that and navigate with your front hitch without any wiring. If you have an electric lockout, you will need to supply 12 volts to that solenoid to release the brakes. I'd suggest getting a matching connector for your trailer like # PK11893 or # HM47900 and hardwiring the reverse wire directly to your battery and run a ground wire to the negative battery terminal from the connector. This will allow you to have that single function to...

    Yes, there is a way to back up your boat trailer and keep the surge brake actuator, # T43397007K, from applying pressure to the trailer brakes. You will need an electric lockout solenoid, # T4748800, which will close when you shift the vehicle into reverse, allowing the trailer to be backed. Along with the solenoid, you will need a solenoid cover, # T4835800183, if your actuator is the model 60 actuator that you referenced. The cover will keep the solenoid from getting stepped on and...

These are combined in a package with part # HM47890 if you need one for both your tow vehicle and trailer. Simply connect the reverse light circuit to the pin location furthest...

Instead of cutting part # A57CCB you could use coiled 7-way plug/cord # WG54006-043, converter # 118158 and 5-pole vehicle-side connector # HM47900. To make the wire connections you can use butt connectors # DW05744-10.
