Hopkins Endurance 4-Way Flat Trailer Connector w/ 48" Harness and Ergonomic Pull

See what our Experts say about this Hopkins Trailer Wiring

• 4-way Options for use With a Tow Ready Mounting Bracket
  The Hopkins 4-way # HM48030 that you referenced is a great 4-way, but like you noticed, it is much larger than most 4-ways so it would not fit through the Mounting Bracket 4-Pole Flat # 18144 that you have. You basically have two choices at this point. You can either buy a different 4-way that will fit through the hole of the # 18144. Or you could cut off your # HM48030 and then run the wires through the front of the # 18144 and then reconnect the wires to the 4-way wiring of your vehicle. Check...

• Does Dolly Towing 2005 Prius Require Use of Additional Lights
  If you are towing your Prius on a tow dolly like # RM-2050-1 that has built-in taillights and turn signals you do not have to also wire the car's lights to operate. However, in the spirit of better-safe-than-sorry it becomes a pretty easy call to add a low-cost set of magnetic tow lights to the car to improve visibility for other motorists. Magnetic tow lights like # TL21RK are inexpensive, easy to install and will only increase your safety on the road. You will need to splice in an additional...

• How to Make a 6-Way Square to 4-Way Flat Trailer Wiring Adapter
  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 # 3808 if needed before installing them in a new 4-Way, #...

• 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...

• 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...

• Troubleshooting no Power to Trailer Turn Signals
  If your trailer turn signals are not working there are a number of different reasons and there are some troubleshooting steps you can take to determine the specific problem. The first thing to do is take a look at your owner's manual to locate where any trailer fuses or relays and ensure they are all there and in working order. If they are, since you tested the plug on your 2001 Chevy and found no signal at the turn signals, check your connector for corrosion, which can be green or white...

• Solution for Turn Signal Error Message on 2017 F-150 When Using Lighted Hitch Cover
  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...

• Troubleshooting Trailer Wiring For Double Towing Camper and Motorcycle Trailer Behind 2016 Tundra
  It sounds like you want to tow 2 trailers and need the wiring for both. It is completely possible to do that as long as your truck can handle the total weight of the two loaded trailers. For the wiring, there are a couple of different options. You can run an extremely long harness like you mentioned that will be a simple customized length or you can tap into your trailer wires to create a harness at the back of your camping trailer. My recommendation is to do the latter. To tap...

• Troubleshooting Error Codes On 2017 Ford Expedition With Pilot Ford LED Light Cover Installed
  Since using the Ford Brake Light Trailer Hitch Cover # CR-007F on your 2017 Ford Expedition is causing an error code, you will need to either add an additional 4-way connector like the # HM48030 to bypass the OEM wiring, or you can add load resistors # DI34ZR to the yellow and green turn signal wires of the cover. The towing system on the newer Ford's can be finicky about adding accessories as it thinks there is a trailer connected but is not seeing the power draw it is programed to expect...

• 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.

• Running Lights Work But Brake Lights and Turn Signals Do Not Work on Coleman Camper
  The best way to start troubleshooting your truck and trailer is to disconnect the two and test each one separately. If you have access to a different tow vehicle or trailer you can test using one of these to isolate the problem to either your truck or camper. Inspect both the vehicle and trailer connectors for signs of dirt, discoloration or corrosion. Even very slight greenish or whitish discoloration on the connectors can interfere with signal transmission. You can try cleaning the...

• Solution for Error Code Caused by Skull with L.E.D. Eyes Cover on 2022 Ford Edge ST
  The reason for the error is the LED in the hitch cover. This has a very low power draw which causes errors in vehicles like your 2022 Ford Edge ST. The only way to fix it is to wire in an aftermarket 4-way like the # HM48030 to bypass the system or add load resistors like # DI34ZR to your stop/turn wires on your 4-way.

• 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.

• 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...

• How to Wire in Dual 4-pole Vehicle-Side Trailer Connectors on RV
  There are several ways to have dual 4-pole flat vehicle wiring on your RV, depending on how the RV wiring is set up. If the RV uses a round U.S. Car connector at the back of its 7-way you could use two of part # 118384 in a daisy-chain set up. This would provide two 4-poles and keep your 7-way active. This is a plug-and-play option. If you don't mind a bit of cutting and splicing you could tap into the wiring that leads to the RV 7-way and splice in two of an item like # HM48030 using...

• Replacement 4-Way Recommendation for Vehicle with 5 Wires Ran to 4-Way
  For a very rugged replacement 4-way for you to use on your vehicle we have the part # HM48030 which would work well. Chances are you have two wires ran to the running light circuit of the 4-way. What you can do is run those wires together and then run them to the one running light wire of the # HM48030 and you would be just fine.

• How Come this 6 Way Square Adapter # 30104 Will Not Work on My 1983 Coleman Pop Up
  The reason you are not getting the lights to work is that this Adapter 4 Way Flat to 6 Way Square for Jayco, part # 30104, is because this adapter is wired to only work on Jayco trailers, and is not wired to work on your Coleman Pop up. Although we can not sell you an adapter that would work on your Coleman trailer because of propriety issues with Coleman, there is a way you could get your trailer lights to function properly. You will need to connect the # 30104 to your vehicle and then...

• No Tail Lights On Boat Trailer When Parking or Headlights of 1995 Ford Truck Are On
  It sounds like you have a common ground problem. When the headlights are on, the highest amperage draw is placed on the wiring system and if you have a bad or loose ground, you will have problems with lights. You will want to inspect to make sure all the light assemblies have a good ground connection to a clean, rust and paint-free metal surface. You will also want to make sure the trailer and vehicle side connector have a good ground connection. I would recommend unbolting the ground...

• 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....

• Options for Connecting to 6-Way Square Connector of Dutchmen RV
  The Jayco 6-way square connectors use a standard connector but a unique pin out. So what that means is that the # 30104 could work for you but you'd have to cut the wires to match the different pin out which we don't have info on. Or you could cut the 6-way off of your Dutchmen and wire a standard 4-way to it instead like with the # HM48030. The 4-Way vehicle end functions will be oriented in the 4-Way as follows: Exposed pin = ground (white wire on harness) Next pin = running lights...

• Parts Needed To Add 4-Way Flat Connector On a Rialta Camper With 6-Way Pin Connector
  To connect your 4-way trailer to your Rialta camper you will need a Hopkins Tail Light Converter # HM48847 and Hopkins Endurance 4-Way Flat Trailer Connector Socket # HM48030. These will allow you to tie into the wiring going into your 6-way connector to combine the turn signals and brake lights to work on the 4-way wiring. The converter is labeled to ensure you connect up the wiring correctly and the socket has mounting holes allowing you to leave it installed. Or you can wire it to a...

• 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.

• Lamp Out Warning on 2020 Ford Explorer when LED Hitch Cover Attached
  I have a solution for you, so never fear-we've actually seen this before on the newer Ford trucks, which will have the same lamp out detection system. If you are getting an error code on your 2020 Ford Explorer when using the Ford LED Lighted Trailer Hitch Cover # CR-007F it's most likely reacting to the lower amp draw from the LED light and the computer is sensing that a lamp might potentially be burnt out, but it also could just be corrosion on the 4way. I would start by making sure...
