Hopkins Wiring - HM47890

The 5-wire design of this kit is perfect for newer boat trailers with hydraulic brakes. Easy-pull connector housings make disconnecting a snap. They include built-in mounting holes and protective dust covers on both the vehicle and trailer plug.


Features:

  • Wiring kit includes vehicle-end connector and trailer-end connector
  • 5-Wire design common on boat trailers with hydraulic brakes
    • Provides backup function to release surge brakes
  • Easy-pull, ergonomic grips on connectors make disconnecting a snap
  • Heavy-duty connector housings have built-in mounting holes
  • Durable, molded dust covers provide superior protection for terminals
    • Tin-plated terminals resist corrosion
  • Nylon sleeves and heat-shrink tubing protect wires
  • Terminal grease packet and ground screw included


Specs:

  • Connector: 5-way flat
  • Vehicle-end wire length: 48"
  • Trailer-end wire length: 18"
  • 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.

Video Transcript for Hopkins Wiring - Trailer Connectors - HM47890 Review

Today we'll be reviewing part number HM47890. This is the Hopkins Endurance 5-Way Flat Trailer Wiring Kit. The wiring kit's going to include the vehicle end connector and the trailer end connector. It's going to feature a 5-wire design that's really common on boat trailers with hydraulic brakes and that simply just allows a backup function. That way the surge brakes can be released. Each housing is going to feature an easy pull ergonomic grip design. It's going to make disconnecting very easy so it's got a nice little surfacing texture and grip there. That way you can get a nice secure hold on it and disconnect very easily from the connection point. The housings are heavy duty. It's also going to feature the built-in mounting holes.

Each housing is going to be identical. It also has the durable molded dust cover that's going to provide protection for the terminals. It simply just fits over there and protects the tin-plated terminals from the elements. Having them tin plated is really going to help it stand up well against rust and corrosion. It's also going to feature nylon sleeves and heat-shrink tubing that are designed to protect the wires. You're also going to get the terminal grease packet and the ground screws, so both of those are included. This is a 5-way flat connector.

This side over here is going to be for the vehicle end. That's going to measure 48 inches in total length and then here the trailer end wire is going to be 18 inches in total length. They are color coded and the wire is already exposed. All you have to do is pull off the tubing and it's going to expose the end of the wire so no splicing is required. So you can see there, I'll pull off one so you can see it. It does expose the wire so you don't really need to trim that back.

They are color coded. Your white's going to be your ground. Your brown is going to be your parking lights or your tail lights. Yellow is going to be for your left turn. Green's going to be for your right turn and blue is going to be for your back up or reverse. That's going to do it for our review of part number HM47890.

This is the Hopkins Endurance 5-Way Flat trailer wiring kit. .

Replaced a round connector that was unreliable and would loose connection over the road. This flat 5 pin makes 100% connection every time and stays connected. The boot is also weather tite when connected or not so there's no corrosion. Great product. 513383

With the help of Crystal I ordered this connector and a matching wiring harness for my motorcycle and trailer. I was unsure if these were the correct parts, but Crystal was able to locate the exact ones and ship them the same day. I was very pleased with the fast service and knowledgeable staff. Even with standard shipping, my order arrived 4 days sooner than was projected. To say I'm happy with etrailer is an understatement. They are great. 453787

The female connector is attached to the swing arm of a motorcycle to provide lighting lighting for a trailer pulled by the motorcycle. This means that there is likely much more movement in the harness than for an automotive application. I've never had a problem with any part of the harness. I found this product to be exactly what I wanted, well made and easy to install. The protective cap functions well as it remains pliable (flexible) after a year of use, and while it has never fallen off in use, it is easy enough to remove before making the connection. It has done the perfect job of keeping mud and other detritus out of the contacts. The recessed nut holders also function well and is one of the reasons I chose this wiring kit. This wiring kit gets high regard and recommendation from me. All of my purchases from etrailer have been solid products delivered at reasonable cost. 247083

Do you have a question about this Wiring?


  • Troubleshooting Brakes Locking Up When Backing on New Tandem Axle Trailer
  • It sounds like your new tandem axle trailer has a surge brake coupler. You will need to use the manual lockout on the coupler if there is one or add a Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts # T4748800. This electric lockout connects to a 5-way trailer plug like # HM47890, and an adapter like the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter # 20036 will connect to the reverse light circuit at your tail light to send a signal to that solenoid to...

  • Recommendation for Wiring to Allow Backing Up With Electric Lockout Solenoid on Surge Brake Trailer
  • For your electric lockout solenoid on your trailer, I don't recommend using the parking lights as your signal. Although this works for daytime without issue, at night you will lose all of your trailer braking. Instead, I recommend you use the Deka Heat Shrink Butt Connectors # DW05744-5 and the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer Ends # HM47890. This will give you a clean connection between your trailer and vehicle and allow you to properly connect...

  • How to Get Reverse Light and Separate Turn and Stop Signals for Trailer Towing
  • To start off your project you need the Hopkins Endurance 5-Way Flat Trailer Wiring Kit # HM47890 this kit includes a 5-Way for your trailer and a 5-Way for your 2007 FJ Cruiser. This will allow you to send the reverse signal to your trailer in addition to the basic trailer functions. You will need to connect the following functions to the following wires: White - Ground Brown - Tail Lights Yellow - Left Turn/Stop Green - Right Turn/Stop Blue - Reverse Once on your trailer side...

  • Adding a Trailer Battery Charge Line to 4-Way Trailer Connector
  • To charge your trailer battery from your vehicle, I recommend the Roadmaster Battery Charge Line Kit # RM-156-75. This can be run to 5 way connection on each side like the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer Ends - Ergonomic Design # HM47890. This will give you a clean connection of both sides to run to your battery terminals.

  • Will Removing Check Valve on Master Cylinder Keep Brakes from Engaging When Backing Up
  • Removing the check valve from the master cylinder for hydraulic drum brakes, like part # T1777401, enables it to put out a greater psi rating so that it will be compatible with hydraulic disc brakes that require the higher psi rating. If you are mechanically inclined and you carefully reassemble the master cylinder then you can remove the check valve. However, if you are less mechanically inclined then it would be better to replace the drum master cylinder with a disc master cylinder,...

  • How to Wire Titan # T4748800 Reverse Lock-Out Solenoid Valve
  • The Titan Replacement Reverse Lockout Solenoid you mentioned is extremely easy to wire. The solenoid has two wires exiting it. One wire grounds to the trailer tongue, the other would connect to the reverse light circuit on the tow vehicle. Once wired, the solenoid will close when the tow vehicle is shifted into reverse, preventing the trailer brakes from applying when the trailer is backed. Since it sounds like both your vehicle and trailer have a 4-pole connector, you'll need to install...

  • Will the Titan Disc Brake Kit # T4843200 Replace the Reliable Brand Disc Brake System
  • It sounds like you are on the right track to confirming if the Titan Disc Brake Kit, # T4843200, will be a compatible replacement to your Reliable disc brakes. Since the Titan hubs/rotors use the same bearings as your Reliable hubs/rotors, they will fit on the same spindle. Also, diameter of the Titan rotors will be 1/2 inch smaller than your current rotors, but that will not affect the installation or compatibility. The included actuator will replace your current Titan D60 actuator...

  • Parts Needed to Backup Without Putting on the Surge Brakes When Parking or Launching a Boat Trailer
  • Yes, there is a way to back up your boat trailer and keep the surge brake actuator, # T43329007K, 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...

  • Adapting a 5-Way Flat Vehicle Side Trailer Connector to a 4-Way Flat for Towing Lights
  • You may be able to plug in the 4-Way flat into the 5-Way flat without an adapter. There will just be one pin that is not used by the 4-Way left over. All the other functions will still work. The pin furthest from the ground pin (on the vehicle side 5-Way) will be the one that is not used. If the two connectors will not fit together, you can use Wiring Kit, # HM47890. You will just need the trailer side of the kit. You will have to replace the connector on the tow lights with the trailer...

  • Installation of Electric Reverse Lockout Solenoid for Surge Brakes
  • If you don't install the reverse lockout solenoid # T4748800 that came with your actuator, then unless you have free backing brake assemblies, you will not be able to back up without activating the brakes immediately. This solenoid basically works like a valve not allowing the hydraulic brake fluid to move through the brake lines to activate your brake assemblies. Because you have a 4-way, I recommend you add the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer...

  • Recommended Wiring For A 1998 Chevy C/K Series Truck
  • For your 1998 Chevrolet C/K-Series 1500, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118315. This harness plugs directly into existing wiring with no splicing to cutting required. This will give you a 4-way connector. If you want to add a 7 way trailer connection, then I recommend the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires, # ETBC7. This will give you all the connectors, circuit breakers,...

  • How to Wire Reverse Lights on a Trailer with a 4-Way Trailer Connector
  • We do have a solution for you, however, you will not be able to power reverse lights on a trailer with a 4-pin trailer connector. The reverse lights on a trailer must receive power from the reverse lights on the tow vehicle. To do this, you will want to install a 5-pin connector on the trailer and on the tow vehicle. There are many options, but I recommend installing the Hopkins Endurance 5-way Flat Wiring Kit, # HM47890, for a uniform look. You can simply cut off the 4 pin connectors...

  • Can a 3-Wire to 2-Wire Trailer Wiring Harness Converter be Bypassed
  • The only way to bypass a 3-wire to 2-wire trailer wiring harness converter (assuming your vehicle has a 3-wire or separate tail light system) would be to convert your trailer to a 3-wire (or separate) tail light system. This means you will need a separate tail light circuit, brake light circuit, and turn signal circuits on the trailer. You will also need to use either a 5-way, 6-way or 7-way style trailer connector on your trailer and tow vehicle and substitute one of the pins for the additional...

  • How to Convert a 4-Way Connector to a 5-Way with Separate Taillight Circuits
  • It sounds like you have a trailer with separate tail lights from the brake light circuit and you are looking to convert the 4-way from your motorcycle to a 5-way. First thing you will need to do is convert your combined tail light circuits to a separate tail light circuit. So like you said you would need another converter box. You would want a Converter Box # 118158 to make that conversion. You will also want to get a Hopkins Endurance 5-Way Flat Trailer Wiring Kit # HM47890 to give...

  • Troubleshooting Trailer Ball Fit and Backing up with the Titan Model 60 for Disc Brakes # T43329007K
  • The Titan Zinc-Plated Lever Lock Actuator # T43329007K that you referenced is adjustable and will fit trailer balls that are 1-7/8 inches, 2 inches, and 50 mm. In order to fit the coupler to the specific size of trailer ball that you have, some small adjustments can be made to optimize the fit. If you are using the Titan Level Lock Brake Actuator # T43329007K, with different size trailer balls to tow your trailer adjustments will have to be made each time a different size trailer ball...

  • How To Connect 4-Flat Vehicle Connector On 2011 Kia Sorrento To 5-Flat Boat Trailer Connector
  • I would recommend the Tow Ready Adapter 4 Pole to 5 Pole Trailer Wiring # 20036 for your 2011 Kia Sorento ES. This adapter will have a 5-flat connector on one end and the other end will have a 4-flat and a extra plug. The 5-flat will plug into your boat trailer conector and the 4-flat on the other end will plug into your vehicles 4-flat connector with the extra plug being plugged into the extra piece of blue wire included in the kit. The blue wire will then be spliced into your reverse...

  • Will Titan Disc Brake Kit and Aero 7500 Actuator Fit A 3 Foot Swing Away Tongue
  • You will just need to order a few extra parts to be able to use the Titan Disc Brake Kit and Aero 7500 Actuator w/ Manual Lockout on your swing away tongue that is 3 feet long. You will need to order the Titan Hydraulic Brake Line with Fittings - 12-27/32 Inches Long, part # T0777300, the Titan Hydraulic Brake Line with Fittings - 30 Inches Long, part # T1061900, and the Titan 3/16 Inch Hydraulic Union, part # T1287900. The 30 inch long brake line # T1061900 will attach to the actuator,...

  • Reverse Light Recommendations for a Motorcycle Trailer
  • If the trailer is one designed to carry a motorcycle, you can add some reverse lights to it. I recommend two lights, one on each side of the rear of the trailer. There are better suited lights for this application. I recommend the Sealed, 6-1/2 inch LED Clear Oval Trailer Utility Light, 10 Diode, # BUL72CB. These lights are submersible. You will also need a rubber grommet, # a70gb, for each light, and a pigtail, # A45CB, for each light. To mount the lights, you can use Mounting Bracket...

  • Adding 5-Way Flat Connectors to Trailer and Vehicle to Use Electric Reverse Lockout
  • The electric reverse lockout included with Titan disc brake kit # T4843200 requires a 5-Way flat on the trailer and vehicle. The lockout solenoid gets power from the reverse light circuit from the vehicle. When the vehicle is placed in reverse it powers the solenoid and does not allow fluid to go back to the trailer brakes. It is actually easy to add a 5-Way flat to the vehicle and the trailer. On the trailer side, you just need to cut off the 4-Way and install a 5-Way flat in its place....

  • Replacing 7-Way Trailer Connector with Smaller Connector to Tow a Trailer with Brakes
  • A 6-way round trailer connector, like # HM48420, once it's mounted isn't going to be much smaller than a 7-way. If you don't need any functions other than running, brake, and turn lights along with the brake circuit I suggest going with a 5-way flat connector like # HM47900. To put a 5-way on both your tow vehicle and trailer you can use the kit # HM47890 that includes both connectors.
    view full answer...

  • Can a Reverse Light Function be Added to a 4-Way Connector
  • Yes, running a separate wire for the reverse light function will work but you will need to use connectors on your tow vehicle and trailer that has 5 pin locations instead of 4. If you just need a 5-Way for your vehicle side then use part # HM47900 but if you need one for your trailer side use part # HM47910. 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...

  • How to Wire a Mid-Trailer Turn Signal on a 24 Ft Haulmark Trailer Towed with a 2005 GMC Yukon XL
  • If the lights at the middle of your trailer are connected to the turn signal circuit then they will go solid when the brake lights are activated since trailers are wired with a two wire system. There really is no easy fix for this problem that I am aware of. One option is to wire a connector with an extra circuit, if your Yukon has separate yellow turn signals at the rear, I believe most do, you could use a 5-Way connector set like the 5-Way Flat Trailer Wiring Kit, item # HM47890, and...

  • Would the Connectors of the Quick Fix (TM) 4 Pole Flat Car and Trailer Ends Attach to a 5-Way
  • The connectors that come with the part # 48195 are 4-way connectors. A 5-way would mate right up to this connector but the fifth circuit would get dropped off. If you are looking for a replacement set of 5-ways for both your trailer and tow vehicle you would want the part # HM47890.
