I used the Hopkins 3 to 2 converter to make a 6-pin round to 4-flat connector for my Winnebago View motorhome. While there are 6-4 plugs available to do this, they do not work on the Winnebago View (no brake lights). This adaptor works great. 145794

Well this is the second one I bought go bad so I just added extra lights and changed trailer plug from 4 to 6 round plug. One failed after using and the other one never worked from the start. All that would work were tail lights. 650336

Easy to install if you know how to splice new wires into the existing wiring on your vehicle and have connectors (not included) to do it. 242943

Products came on time and exceeded my expectations. I've placed 3 orders with them over the last 6 weeks and have been thrilled. Highly recommend them. While free freight would be a nice adder I did find that they used the US Post Office for under 3 bucks on one of my orders whereas others would have charged around 15 bucks for UPS for the same items to be shipped. I really liked that!!! 217510

Do you have a question about this Wiring?


  • Installation of 4-Pole Wiring Harness on 1998 Ford F-150
  • On the 1988 Ford F-150 the brake and turn signal lights are already converted, so a converter is not required. For your F-150 vehicle, instead of the Hopkins Vehicle Wiring Converter, part # HM48915 I would recommend the T-1 connector part # 118316. I will provide you a link below to the installation instructions for the T-1 connector as well as an installation video. The T-1 plugs inline into the connector that is usually located on the left side frame rail. The existing wiring harness...

  • 4-Pole Wiring for my 1995 Jeep Grand Cherokee
  • Yes, you can use the Hopkins Vehicle Wiring Converter with 4-Pole End, item number HM48915, to wire your Jeep for a 4-way trailer connection. Keep in mind that this unit will need to be hard wired into the vehicles taillight circuits and that it only supplies 2.1 amps per function so the trailer can only have lights at the rear and no extra lighting. You will need to use a circuit tester, item # 40376, if you need one, to find the correct wiring to splice the connector to. An easier...

  • Will Hopkins Vehicle Wiring Converter HM48915 Operate Turn Signals In-Phase with Vehicle
  • The Hopkins Vehicle Wiring Converter # HM48915 will do what you need; it will take the separate stop and turn signals from the individual lights on your 1999 Nissan Frontier and combine them onto one wire as required by typical trailer lighting systems. With this in place you could then add a set of magnetic towing lights like # TL21RK. I confirmed with my technical contact at Hopkins that this converter's turn signal output will be IN PHASE with the vehicle's turn signals. You might...

  • Recommended Trailer Wiring Harness Options for 2002 Jeep Liberty
  • If you're comfortable with the process of using a circuit tester like # 40376 to locate which circuit serves which taillight function, and then tapping the input wires for the Hopkins # HM48915 taillight converter into those circuits, you can certainly use that option. This being said, the Curt # C55382 converter would be a plug and play option that would be much easier to install. Better still would be the Tow Ready # 118524. The Tow Ready is also a plug and play option, but instead of...

  • Trailer Wiring Kit # HM48915 Troubleshooting for Use a 2006 Dodge Ram 2500
  • It sounds like you have a short either in the way you are wiring up the Hopkins Vehicle Wiring Converter, part # HM48915, or your trailer has a wiring issue that shorts out the entire circuitry of the # HM48915 and causes all of the tail light functions of your trailer to not work. First thing I would check is that the way you wired in the # HM48915 to your tow vehicle. First thing I would do is wire the red wire from the # HM48915 to the wire that has voltage when the brake pedal...

  • Can Hopkins Trailer Wiring Harness HM48915 be Used on a Honda Goldwing with Separate Brake Lights
  • You can use the Hopkins trailer wiring converter, # HM48915, to converter the 5-wire harness on the Goldwing to a 4-way used by your trailer. On the harness the red wire is for brake lights and would connect to the blue wire on your motorcycle wiring. All the other wires, green, yellow, brown, and white, will attach color for color to the motorcycle harness.

  • Trailer Wiring Harness Recommendation for a 2011 Ford Escape
  • Technically you could use Hopkins trailer wiring harness # HM48915 on your 2011 Ford Escape. But since your 2011 Ford Escape uses a combined wiring system (brake lights and turn signals on the same bulbs) you would ground the red wire with the white wire. Brown is for running lights, yellow is left turn/brake lights, green is right turn/brake lights, and white is ground. Using this harness means you would have to splice into the vehicle wiring. For a much easier installation I recommend...

  • Adding a Trailer Wiring Harness to a 2000 Harley Davidson
  • We do have some wiring harnesses that you can use on your 2000 Harley Davidson but they are not T-connectors, they are all hardwire. A harness like # 119147KIT would work for you. The green wire taps into the right turn signal, yellow for left turn signal, red for brake lights, and brown for running lights. This unit will also need to be connected to the bike battery and what this does is actually power the trailer lights to help isolate the bike wiring from the trailer wiring for additional...

  • Trailer Wiring Harness with 4-Way Flat Connector for 1997 Honda Valkyrie
  • First, with LED lights, the color of the bulb needs to match the color of the lens. Otherwise you will have dim lights or off-color lights. If you want you can replace just the 4-Way end on the harness that you have with # HM48190. If you want to replace the whole harness I recommend going with a powered option such as # 119190KIT which will get the power for the trailer lights directly from the battery instead of drawing it through the tail light wiring.

  • Converter Needed to Activate Separate Brake Light of Trailer Wiring that is Separate
  • Well the part # HM48915 that you referenced is not designed to provide a separate brake light out from the rest of the wiring so if the separate brake lights you mentioned are not activating it's because of that. What you would need is to install the part # RM-732 on the trailer side of your wiring and the red wire would be what you would need to run your separate brake light to.

  • Will Hopkins Wiring Converter # HM48915 Work on 2000 Plymouth Neon Towing Trailer With LED Lights
  • The Hopkins Vehicle Wiring Converter, part # HM48915, is used for a vehicle that will have a 3-wire system, which means it would have separate stop and turn signals, to plug into a trailer with a 2-wire system, which has the stop and turn signal combined. Your 2000 Plymouth Neon will have a 2-wire system, so the # HM48915 converter is not needed. To get a 4-way on your Neon you can use the Draw-Tite Wiring Hardwire Kit, part # 18252. Using the included circuit tester these wires will...

This wiring harness is designed for use on vehicles that have amber or independent bulb turn signals which should be what is on your 1991 Ford Aerostar.

  • No Right Turn Signal Using HM48915 Wired to A Motorcycle
  • First, It is a good idea to double check the ground from the Hopkins Converter part # HM48915. Make sure it is grounded to a clean bare metal surface. If your ground connection is good, check that you are getting power to the right turn wire from the motorcycle's before the converter. if you are not getting power from the wire at the motorcycle, check the wire for any damage or frayed wiring. If you find you are not getting power from the right turn wire on the motorcycle, then those...
