4-Way Trailer Connector Installation

Because the color/function of the wires on this connector may not match the color/function of those on your vehicle, be sure to use a tester (sold separately) to double check the function of each wire on your vehicle's tail light wiring harness before installing this connector. Once you've figured out the functions of your vehicle's wiring, use quick-splice or butt connectors (sold separately) to connect the corresponding wires on the trailer connector.


The number 1 reason trailer wiring comes up faulty is a bad ground, so make sure your ground wire has a solid and clean connection to metal. To make this connection, you'll need a self-tapping screw (sold separately) and the the included ring terminal.


Wiring Configuration

Wire Color Wire Function
Green Right turn and brake light
Brown Tail lights and running lights
White Ground
Yellow Left turn and brake light


Connector is Easy to Mount

This connector can be mounted on your bumper or attached to another bracket (sold separately) that mounts under your bumper. Simply run self-tapping screws (sold separately) the through molded-in holes on the connector housing.


Quick Tips:

We install a lot of wiring harness around here, so we thought we'd share a few tips we've picked up over the years:

  • Butt connectors - especially heat-shrink ones - provide the most secure, longest-lasting connection, so we'd recommend you grab a few and swap them out for the quick-splices in this kit.
  • Use a circuit tester on the plug terminals once the harness is installed to make sure everything's working. There's nothing worse than figuring out that you have a bad ground or a faulty connection right before you're about to hit the road.
  • Be sure to put a little bit of dielectric grease on the 4-way plug to protect the terminals from dirt, grime, and corrosion.

Hitch for 2018 EcoSport SES. Easy to install and looks good. Wire end with cover also looks good

Product was awesome. My last two connectors have corroded so bad within a year that I constantly was having to take a wire brush and clean off the pins to get good contact. I'm waiting to see what the environmental cap does to eliminate me having to do this. Also bought the vehicle side. Would highly recommend this to anybody with a trailer hook-up. Only thing I would suggest is to make sure anybody purchasing also buys the splices since none come with the product. All in all, a great buy. Thanks!

Using dielectric grease in the trailer connectors can also help reduce corrosion of the contacts.

  • How to Make Coiled 6-Way to 4-Way Adapter
    I personally don't like using adapters if I don't have to so what I would do is use the part # RM-1064-B for the coiled section, the part # HM48440 for the 6-way section and then for the 4-way use the # HM48030 wired up correctly and you'd have a coiled 6-way to 4-way adapter without using any adapters that would work very well.

  • How to Make 6-Way to 4-Way Coiled Adapter for Flat Towing Vehicle
    Since there isn't a 6-way to 4-way coiled adapter like you are looking for you'd have to piece together the kit you are in need of with the part # PK11604 for the 6-way, the part # RM-1064-B for the coiled wire section, and then for the 4-way part # HM48030 and you'd be set.

  • How to Stop an LED Accessory from Tripping the Towing Sensor on a 2019 Ford F-350
    So this will sound odd, but sometimes these kinds of accessories that plug into the vehicle's trailer plugs can trick them into thinking a trailer is connected. That being said, the work around is equally odd. As most of these will utilize a 4 Flat harness for the power and signals, you simply need to install another 4 Flat harness, like the Hopkins Endurance # HM48030, directly to the corresponding wires behind the tail lights. This is a pretty common occurrence with the Ford F-Series trucks.

  • Can 4-Way Trailer Wiring Plugs Connect to Battery for Interior Light
    Yes it would be possible to wire a 4-way to a 12 volt battery if you wanted to. You'd need a 4-way like the part # HM48030 and the part # HM48110 to run one of them to your battery and the other to your light. Otherwise you could run the vehicle side 4-way to the battery.

  • What Wiring Harness do I Need to Use the Saris Light Bar # SA4426?
    The plug you need for the Saris Light Bar SA4426 is the Hopkins Endurance 4-Way Flat Trailer Connector Socket - Vehicle End # HM48030. While we do not have any harnesses that measure 5 feet long, this one is the closest (4 feet long). This plug comes with a weatherproof, insulated lid that covers the terminals. For waterproofing at the wiring points, I recommend the heat shrink connectors # DW05745-5. From checking your past orders from us, you purchased the Swagman Chinook # S64683 and...

  • How to Access 5th Wheel Taillight Wiring for Installing Wiring Harness
    Usually, it will be necessary to remove interior trim panels to access the taillight wiring of a 5th wheel. If your particular trailer's taillights offer access from the exterior, then you'll have an easier time getting to the wiring to allow you to test it for function. It is worth contacting the trailer maker with your VIN to see if they can offer you guidance for accessing the wiring. You will want to use a tester like # PTW2993 to confirm the signal carrier on each RV taillight wire...

  • Converting a 6-Way Rectangle Plug on a Monaco Diplomat to a 4-Way Flat for a Boat Trailer
    The 6-Way square trailer connector is not used by a lot of trailer manufacturers. A lot of Jayco trailers may have them but mostly you come across the 4-Way flat, like what you have on your trailer, and the 7-Way blade for RV applications. What I recommend is to convert the 6-Pole on the Monaco to a 4-Way. You can do this very easily by removing the 6-Way plug, and then testing the wires for function using a circuit tester like # PTW2992 if needed before installing them in a new 4-Way,...

  • 4-Way Extension Recommendation for Rear of Ford F-250 For Towing Second Trailer
    The Curt T-Connector part # C55774 that you referenced would be the first component you'd want. This will give you a 7-way and 4-way active at the rear of your truck. This will allow you to run a 4-way extension from the truck to the second trailer to activate the turn signals. For an extension you could use the part # A40W42B which is a 40 foot section of 4-way wiring that includes a male 4-way and then to the other end you could attach the part # HM48030 and you'd be set.

  • Recommended Wiring To Add Trailer Harness And Brake Controller To 2016 Ford E-450 Cutaway
    We do not offer any wiring harnesses that are designed for your 2016 E-450. I am afraid any trailer wiring you want to do is going to be a hardwire effort. We do offer universal wiring harnesses that will work for you, but you will need to identify the wires for each of the functions by using a circuit tester like part # PTW2993. You will need to first install a 4-way harness like part # HM48030. You will also need a 7-way connector for the RV, so I recommend part # ETBC7. This plugs...

  • Part Recommendations For Flat-Towing A 2006 Hummer H3
    In order to be able to flat-tow your 2006 Hummer H3, there are 5 items needed. You will need base plates for the Hummer, a tow bar, safety cables, lighting for the H3, and most states now require a supplemental brake system. The base plates I recommend are the Roadmaster Base Plates, part # 2505-3. When the front arms are removed the system is virtually invisible. The tow bar I recommend is the Roadmaster Falcon 2 Tow Bar, part # RM-520. This tow bar has a weight capacity of 6,000 lbs....

  • Replacement Vehicle & Trailer 4-Pole Ergonomic Style Pigtail Connectors
    4-pole trailer wiring is usually described as vehicle-side and trailer-side since the male/female description that works well for other items can be confusing when applied to connectors. The part you referenced, Optronics # A35W42B, is a 42-inch trailer-side 4-pole harness with dual brown running light wires which is why it is called a wishbone harness. For a vehicle-side 4-pole pigtail with finger grips you can use # HM48030 or part # HM48110 for the trailer side. You can use butt connectors...

  • Replacing Damaged Vehicle-Side 4-Pole Connector on Curt Wiring Harness
    Yes, you can replace just the damaged connector on the 4-pole harness on your 2013 Hyundai Santa Fe GLS. Hopkins part # HM48205 includes both vehicle- and trailer-side connectors (giving you a spare for the trailer) and quick-splice connectors. Similar products you might prefer include # C58044 that gives you a 60-inch length and # HM48030 which features an ergonomic-style plug. You will connect the white, brown, yellow and green wires color for color. I suggest wrapping the splices with...

  • Correct Vehicle and Trailer Side Hopkins Endurance 4-Way Flat Trailer Connector
    The Hopkins Endurance 4-Way Flat Trailer Connector part # HM48110 is a trailer side connector which is designed to be installed on the towable. If you're instead looking for the vehicle side which is designed to be installed on the tow vehicle then you will need the Hopkins Endurance 4-Way Flat Trailer Connector part # HM48030. These harnesses both require splicing whether you are just replacing a trailer connector or wiring one for the first time.

  • Recommended Replacements for Factory 4-Pole Trailer Connector on 1999 Dodge Dakota
    You have two alternatives for replacing your factory 4-pole trailer connector. First, you can simply abandon the old connector by taping it up out of the way and use what's called a T-Connector like part # 118329. A T-Connector would plug inline with the factory connector between the vehicle's taillight wiring harness and the taillight assemblies. This solution works well, but if your trailer has more lighting than one pair of stop/turn/taillights at the rear you'll want retain the factory...

  • Replacement Trailer Wiring Harness For 2013 Toyota Tacoma
    There are a couple options depending on the wiring you have on your Tacoma. If you smashed your 4-way connector on your truck and want to replace the entire wiring harness then I recommend part # 118496. This plugs into the vehicle wiring either behind the tail lights or along the frame rail of your truck. This includes the tail light converter and is a plug and play harness. If you tore up the 4-way connector you can simply just use a 4-way connector like part # HM48030. You can match...

  • Troubleshooting Running Lights Circuit on Factory 4-Pole Wiring on 2011 Ford Ranger
    The best way to evaluate the operation of the factory 4-pole wiring harness on your 2011 Ford Ranger is to use a circuit tester like # PTW2992 but there are also checks you can do without a tester. It is possible that you may have just a corrosion problem on your 4-pole, and this is easy to check. Inspect the metal contact surfaces for any signs of even slight greenish or whitish discoloration. Pay particular attention to the pin for the brown (taillight) wire. Clean the contacts as necessary. Another...

  • Wiring Needed For Adding a 4-Way Flat Trailer Connector On a Toyota Land Cruiser With 24V Power
    First you are going to need to determine if your Toyota Land Cruiser has a full 24 volt wiring system or if the 24 volt is only ran on the starting system. This was the most common way several of the vehicles were wired so the tail lighting and other functions would all still use 12 volt power. This would allow you to use the Wiring Harness # C59496 to get a 4-way flat connector. A Multimeter # PT89ZR can be used to verify if your current lighting is 12 volt or 24 volt. If you have 24...

  • Adapting a 7-Pin European 7-Way on 1999 Range Rover to US 4-Way Flat Trailer Connector
    You would have the same problem using adapter # 118710 as you would with just splicing in a 4-Way. The adapter doesn't convert the separate signals to combined signals used by most trailers in the US. You would need to add a converter, # RM-732, which will take the separate signals and combine them. You could then wire in a 4-Way flat such as # HM48030 on the output side of the converter.

  • Changing Trailer From 6-Way to 4-Way
    If you wanted to change the wiring on your trailer to match the 4-Flat on your van, that would be the simplest solution. All you would need to do is cut off the 6-Way, use a circuit tester # PTW2993 on the vehicle side to make sure you know each of the wire's functions and then install them in a 4-Way # HM48030. Keep in mind you will also need to use a separate 12V power source such as a battery in order to test the trailer's functions.

    The only way to use your Pilot Skull Lighted Hitch Cover # CR-018 with your 2017 Ford F-150 without getting the turn signal error message would be to hardwire in a new 4-Way connector like # HM48030 to use with the cover. This will allow you to bypass the trailer tail light sensors on the truck so that the error message doesn't come up. I realize this sounds like silly workaround since you already have a working 4-Way but it is unfortunately the only option that would prevent that error...
