2017 Nissan Leaf

Used this on my 2017 Nissan Leaf. The wires were just long enough, and I used Posi-taps to connect them. The recommended product for my car doesn't require tapping into the car's wires, but requires running a hot wire all the way to the battery. I really didn't want to do that.

My trailer has all-LED lights. The car has LED stops and tails, so not sure this setup would work well with incandescent trailer lights.

Still working well

Ordered the HM48895 trailer light converter for my Honda Sabre motorcycle. It was an easy install and works like advertised. Great product. Fast shipping.

Toyota Tacoma

I was having problems finding the right replacement 5-wire to 4--wire converter for the custom LED brake lights/turn signals on the flatbed conversion to my Tacoma pickup. I called's help line and described my problem to Bridget E. She knew exactly what I needed (a converter made especially for LED brakelights/turn signals), and shipped it out right away. Two days later I had it in my hands here in Hawaii. Nice! This is a high quality converter at a good price. I am pleased with both the service and the merchandise at Highly recommended!


The product fooled me a bit . I thought it was from 4 wire to 5 wire , but it was 5 to 4 . Which worked out fine , on my VW Bus . The product works well and i recommend it . But make sure you don't want the 5 wires going to a 5 wire motorcycle trailer . Because the 5 wires need to connect to a European Cars 5 wire set up .


Just what I needed and it was at a fair price


Exactly as ordered...shipped on time


Price is great fast ship when wireing a sand rail or dune buggy this is a great product saves time and space

2008 Harley Davidson Street Glide

Harley Davidson

Have had my Hopkins wiring adapter on my Harley for a good year now and still working perfect. Nice to know I can now hook up to any small motorcycle trailer with out trying to obtain wiring plugs from this one to that one and not pull my hair out. Great product.

2006 Harley-Davidson Heritage Softail Classic

George J. I ordered the convertor to put on my 2006 Heritage Softail Classic to pull a Harbor Freight Tagalong Trailer and it worked great and fit under the seat with no problem. Sorry no pictures. Thanks again Rick


The equipment works good, I'm happy with my purchase.


Great wiring harness

2011 Nissan Versa

Simple to wire and a complete solution to my trailer wiring. All I needed to add were the Scotch Locks. Wire lengths adequate to the job so no extra splices. Works with my low amp LEDs.


This is the second time we have ordered from e-trailer. Both times the
items were received within two days. Both times the parts were
exactly as pictured or ordered. Great service! Perfect Parts!
Both parts were also hard to find parts which made the experience
even that much better. Our customer's more than appreciated being
put back in service so quickly. :)

Harley Davidson

This is the second one of this I have had they are great for going from a five wire to a four wire configuration. I actually put this one on a Harley Davidson.


Everything worked as it was supposed to. I'm ready to pull a trailer!

2000 Chevrolet Silverado

Worked perfectly for the application it was needed for.


I received a quality product that actually works correctly. The product was delivered in a timely manner. Thank you!

2009 Chrysler PT Cruiser

Good product at the right price. Great service from the company.

Ask the Experts about this Hopkins Trailer Wiring

  • Is Hopkins Tail Light Converter Kit with 4-Way Flat Connector # HM48895 LED Light Compatible
    Yes, the Hopkins Tail Light Converter Kit with 4-Way Flat Connector # HM48895 is compatible with LED type lights and incandescents. It's listed on our site as LED compatible which may be misleading as it can also work with incandescent bulbs as well.

  • Can Hopkins Trailer Wiring Harness be Used to Wire LED Lights on a 2004 Dodge Ram Flatbed
    Yes you could use Hopkins converter # HM48895 to combine the separate brake lights and turn signals on your 2004 Dodge Ram to work with LED lights that require combined brake lights and turn signals. You would have to cut the 4-Way end off and hardwire the wires to the lights but other than that it will work.

  • Converter Recommendation to Take Separate Turn Signals and Convert them to Combined

  • Recommended LED Tail Light Wiring Harness For 1996 Ram 1500 Flat Bed
    To connect your 3 wire LED lights in your 1996 Dodge Ram 1500 flatbed, I recommend using the Hopkins converter # HM48895 to combine the separate brake lights and turn signals to work with LED lights that require combined brake lights and turn signals. You will have to cut the 4-Way end off and hardwire the wires to the lights. This converter is designed specifically for use with LED lights.

  • Troubleshooting Low Output Voltage on Hopkins Trailer Taillight Converter Box
    It's possible the converter has an internal short and is damaged. Or it could be possible that you have a weak ground for the converter. Most likely though the box has shorted out. They are designed to fail as a way to prevent a short in trailer wiring from making it back up to the vehicle wiring so that is what is happening. You'd want to track down the short on the trailer wiring and fix it before replacing the converter.

  • Troubleshooting Both Turn Signals Flashing With Hopkins Tail Light Converter Kit
    It is pretty unlikely the converter failed if the issue is that both turn signals turn on when you engage the right turn signal. Instead the issue is almost certainly a poor ground which is causing this. I would re-check the ground connection with the Hopkins Tail Light Converter Kit with 4-Way Flat Connector # HM48895 and ensure it is grounded to a clean, bare metal surface free of any type of paint or corrosion. In most cases when you have one signal turning on both, the ground connection...

  • Troubleshooting No Brake Light Signal After Installing Hopkins Tail Light Converter HM48895
    Since you confirmed that you have brake light signal on the red wire, but are not getting brake lights there is one of two things happening. One is that the ground is not getting a good connection which causes issues when more than one function is trying to work like what you are experiencing. I would double check that the white wire is securely connected to clean, corrosion free metal. If the ground checks out then the converter may have an internal issue since you mention power is coming...

  • Recommendations for Wiring Harness on 2002 Ford Windstar and Trailer
    We do have a wiring harness option for you, but the Hopkins Tail Light Converter Kit # HM48895 you referenced is not a compatible fit on your 2002 Ford Windstar. I would recommend the Hopkins # HM40615 that is custom-made for your vehicle. It provides a 4-pole late trailer connector to your Windstar and features quick and easy installation. I have provided links to the instructions for the proper installation of this item as well as a link to a video showing its installation on a 2002...

  • Troubleshooting Hopkins Tail Light Wiring Converter
    It sounds like you may just need to replace your wiring converter with one made for use with LEDs, the Hopkins LED Compatible Tail Light Converter Kit # HM48895. This is designed to work with the lower power draw of high-efficiency LED lighting. If you test the motorhome wiring and confirm that the signals are present there as they should be then either your converter is damaged or it is simply the wrong one for your application.

  • 2005 Monaco Knight Motor Home and Trailer Hazard Flashers not Working Troubleshooting
    The best way to start is to do a quick inspection of the components involved, then if there is no immediately recognizable issues proceed to testing wiring to determine if the problem is the trailer or your motor home. I would recommend doing a quick inspection of the following items before testing wires: Check to make sure all electrical connections are secure, also look for any corrosion or indications of moisture within connectors. Make sure that all grounded wires are grounded...

  • Parts Needed to Convert a Separate Tail Light Signal of a Honda Goldwing to Combined for Towing
    It sounds like the adapter you used dropped the brake light circuit when it went from a 5-way to a 4-way. Normally on a 4-way the brake light circuit is on the turn signal circuit. Motorcycles usually have a separate wire/circuit for just the brake lights separate from the turn signals so I believe that is where your problem is from. I believe I have a solution for you, but not with using the adapter you have. I would recommend you cut off the 5-way on your motorcycle. Wire in a tail...

    The Hopkins wiring harness # HM48895 is a universal type of harness but it is not one that is recommended for a 2005 Jeep Grand Cherokee Laredo. I have included a link to all of the wiring harnesses that are recommended for your vehicle.

  • Trailer Wire Harness Recommendation for a 1986 Jeep CJ-7
    Your 1986 Jeep CJ-7 uses a combined lighting system, meaning the turn signals and brake lights run on the same wire, so a converter would not be required to install a trailer wiring harness. You could use the Draw-Tite 4-Pole Hardwire Kit, # 18252, to install a trailer wiring harness. This kit comes with the vehicle side 4-pole trailer connector, quick splices and a circuit tester. To install this harness, you will first want to locate the Jeeps tail light wiring. Using the included circuit...

  • Wiring Installation Instructions for Hopkins LED-Compatible Tail Light Converter # HM48895
    The trailer wiring harness you referenced, Hopkins # HM48895, is intended for vehicles that use LED tail lights which draw relatively little power as compared to standard incandescent lights. I do not believe that your 1995 Ford Explorer came equipped with LED-type lighting and this harness is not among those recommended for your vehicle. The red wire on this harness does connect to the brake light circuit as you noted in the instructions. You can identify which wire at your Explorer's...

After connecting to the wiring behind the tail lights you simply run the hot lead to the battery using the included fuse and you have a 4-way connector at the rear of the vehicle.

    You are correct, your 2012 GMC Sierra does have a combined wiring system with the brake lights and turn signals on the same circuit. There are a couple of options you could use to get a dedicated brake light only signal for the brake light on the cap. First, under the dash of your truck, to the left of the steering column there are some tow package wires held together with a white tag. If you pull them down there should be a light blue or orange wire that carries a brake light only signal....

  • No Output From Wire Harness Converter On 2006 Toyota Tacoma
    If you are using a circuit tester like part # 40376 and finding that you have a signal going in to the converter and not coming out, chances are that the converter is bad and needs to be replaced. This harness is designed to adapt your tow vehicle's 3-wire, separate tail light system to the trailer's 2-wire, combined system.

  • Trailer Wiring Recommendation for a 1998 Nissan Frontier
    For trailer wiring for your 1998 Nissan Frontier I have a much better solution for you than a universal wiring kit like the part # HM48895 that you referenced.

This is a custom fit kit that is designed to plug right in line with the taillight wiring of your vehicle and won't require any cutting or splicing.

    It sounds like there may be a short in the wiring for your Tacoma. You can do a quick test by using a circuit tester like part # 40376. To see if the converter on the # HM48895 is sending an output signal to the right side, have someone turn on the right turn signal while you use the circuit tester and check the pin on the 4-way connector that the green wire is attached to. If it shows no power check the green wire that is coming out of the converter. If that shows no power, check the...

    For starters, I'd review the installation. Use your voltmeter or a circuit tester like # 40376 to probe the taillight circuits. Activate the left turn signal, and probe the wires until you find the wire that makes the tester blink or voltage pulse. Tap the yellow converter wire into that circuit. Do the same for the left turn, tap the green wire into that circuit. Push the brake pedal, and test the wires. Tap the red wire into the circuit that goes hot when the brake pedal is pressed.

All you have to do is install the connectors of the harnesses in line with the taillight connectors on your vehicle and the 4-way of the kit will be active and ready to go.

    The Hopkins Tail Light Converter Kit with 4-Way Flat Connector part # HM48895 will not work on a 6 volt system. We also don't have any trailer wiring harnesses with a converter box that will work on a 6 volt system. The issue is with the converter box itself as it is not equipped nor designed to be used on a 6 volt system. However, this converter box will only be needed if the vehicle's lighting circuit cannot handle the additional draw of the trailer lights. As long as the vehicle's lighting...
