  • Hopkins

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.

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.

It works, still. Does the job I need it to do. Not much more to say. In general, I tend to like the stuff that Hopkins makes.

The quality of this connector is great. I installed ea one end to the hitch platform on the motorcycle and bolted it down then did the same on the trailer. I used the old connectors to make a jumper between them. Works great and I don’t have to worry about wires getting damaged. Love it

Still working great

One year after installing the conversion of drum to disk brakes on my single axle EZ Loader boat trailer, the brakes continue to work perfectly. I've had no reason to seek assistance on service or warranty.




by:

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.

The Hopkins Endurance 5-way flat trailer wiring Kit PN HM47890 and wiring clips PN 464600 arrived ahead of the time scheduled and are of a higher quality than we expected. Thanks a million!

Worked perfect....the mounting was great and placed the wiring neat and clean by the hitch on my Street Rod ...........I have you bookmarked for future purchases.

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.

  • How to Wire 5-Way Flat Trailer Connector for Hydraulic Surge Coupler
    The vehicle end of the Hopkins # HM47890 would install on the vehicle by tapping the green striped wire into the right turn, the yellow striped wire into the left turn and the brown striped wire into the running lamp circuit. The remaining blue striped wire would tap into the reverse lamp circuit. The white striped wire would ground to the vehicle frame. On the trailer end, the connector would install the same way, with the extra blue stripe wire connecting to the reverse lockout solenoid...

  • Installing Trailer Brake Wiring to Existing 4-Way Trailer Wiring
    Since you already have the 4-way trailer connector like # 18004, to add your electric brakes you simply will use the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer Ends - Ergonomic Design # HM47890 and match color for color with your existing 4-way. The 5th pin will be used for your trailer brakes instead of a reverse light which is the other typical application for 5-way wiring using that blue wire on the trailer side. The same will be done on the vehicle side...

  • 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...

  • 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.

  • Trailer Side 5-Way Cover for Wiring Connection Availability
    For a 5-way trailer side we don't have the cover alone. You can use the Hopkins Endurance 5-Way Flat Trailer Connector - Trailer End - Ergonomic Design # HM47910 which has the integrated cover, or you can use a 5-Way Flat Trailer Connector In-Line Circuit Tester # 20115 to cover those connections. For wiring with integrated covers for both sides of the connection, you can use the Hopkins Endurance 5-Way Flat Trailer Wiring Kit - Vehicle and Trailer Ends - Ergonomic Design # HM47890.

  • 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.

  • Will Disconnecting Brake Line Via Quick Disconnect Allow Backing up Trailer
    That could potentially work but I'd be worried about putting too much pressure on the check valve on the actuator side and having that blow or forgetting to reconnect the line and traveling without active brakes (which could also blow the check valve). What I recommend doing is replacing your actuator with one like the Titan # T4339720 with an electric lockout and then using the kit # HM47890 to get the reverse signal sent to the actuator. When the actuator receives the reverse signal the...

    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 Honda Civic to a 5-way and then remove the 6-way round connector from your trailer and install 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...

    Your vehicle has a ground side switching reverse light circuit. You can use the 5-Flat Vehicle End 72 Wiring Harness, item # 20016, on your vehicle to install all of the connections from your original 4-Way connector and then wire the reverse light circuit.

    For the rear of your your truck the Curt Trailer Connector Adapter # C57187 will plug into your current 4-way and there is a additional wire that you will tie into your reverse light wiring on your vehicle. This is what will send power to the electronic lock out on your trailer surge brake. For getting this connection to the front of your vehicle when you use a front mounted hitch I recommend using the Hopkins Endurance 5-Way Flat Trailer Wiring Kit # HM47890 that comes with both the...

  • Is There a Manual Lockout Key for the Titan Model 20 Surge Brake Actuator
    I do have an option for you but the Titan Model 20 Surge Brake Actuator doesn't have a manual lockout key nor do we have one compatible. That said, if you need to lockout the actuator you can simply install a bypass solenoid, the Replacement Solenoid Valve for Titan Brake Actuators with Reverse Lockouts part # T4748800. This will require a 5-way connector so if you don't have one already I recommend the Hopkins Endurance 5-Way Flat Trailer Wiring Kit part # HM47890 which comes with both...

  • 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 your...

  • 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.

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...

  • 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...

  • Parts Needed to Add 5-Way Connector to Trailer and Tow Vehicle
    Ok, so we have exactly what you need, and since your trailer has surge brakes what you'll need for the trailer is a 5-way trailer connector. Since it sounds like you want to use those surge brakes you will also need to cut off your vehicle's 4-way and add a 5-way connector to the vehicle.

  • How to Wire Trailer Reverse Lamps On Trailer With 4 Pole Trailer Connector
    The easiest way to get the reverse lamps to function on your trailer without rewiring the vehicle would be to replace the existing 4 pole with a 7-way trailer connector. The fifth pin on the # HM47890 you'd looked at could be used, but you'd need to rewire both the vehicle AND the trailer. I have an easier suggestion.... We offer a 7-way connector/junction box as part # e99011 that would be perfect for this sort of installation, as the junction box provides a good spot to neatly make your...

  • Adding 5-Way Flat Connectors to Trailer and Vehicle to Use Electric Reverse Lockout
    The electric reverse lockout included with Titan disc brake kit # T4748800 requires at least 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...

  • 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...

  • Does Electric Lockout on Demco Hydraulic Brake Actuator Have to be Connected to Backup Lights
    If you only have an aftermarket backup camera tied into your OEM wiring then I'd be surprised if the electric lockout on the Demco Hydraulic Brake Actuator # 8608611 blew any fuses. I suppose you could technically wires it to any 12V power source as long as you made sure it sent power back when you are backing up, but then you run the risk of damaging trailer and tow vehicle components so I don't really recommend doing that. It would be best to connect it directly to the reverse light circuit. If...

  • Does the Dexter DX7.5L A-60 Brake Actuator Have a Lockout
    The Dexter DX7.5L A-60 Brake Actuator part # DX33FR comes with a manual lockout key for reversing. That said, if you would like for this to be done automatically you can simply add an electric lockout, the Solenoid Valve part # T4748800. That said, you'll also need a 5-way on the trailer and vehicle for this so if you don't already have one I recommend the Hopkins Endurance 5-Way Flat Trailer Wiring Kit part # HM47890. The Dexter DX7.5L A-60 Brake Actuator is made in the USA.

  • If Surge Brake Actuator is Removed Will Trailer Brakes Still Activate
    If you were to remove the surge brake actuator from your trailer then there wouldn't be any pressure to your hydraulic brakes which means your brakes simply won't activate at all. I recommend installing a reverse lockout solenoid like the Titan # TK71-755-00 or the Demco # DM5404 because it ties in to the reverse light function on your tow vehicle and essentially prevents your actuator from applying pressure to your hydraulic brakes. Keep in mind that you'll need to install a 5-Way flat...

  • 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...
