This kit was just what I needed for my situation. With the variety of vehicle light combinations, and various power requirements, trailer connections can get complicated. But etrailer seems to have exactly what is needed in each situation. Once you choose the correct Hopkins kit, ordering is easy, and shipment is quick. 489231

It wired up nice and easy. It’s very compact the instructions are very clear. Great customer service. Though it was a bitch to figure out which wires deadwood on my particular cars taillights, I had to test each wire to figure out what its function was in order to hook the correct wires together. A lot of people on YouTube were using quick splice Connectors, I soldered all of my connections. I recommend doing that 449343

Outstanding! Solved my motorcycle to trailer wiring nightmare easily. My hats off to Sheila for finding a great solution. My old Gold Wing now can safely tow our equally old Bushtec, which we also updated with new LED lights from etrailer. 485847

Not only was I pleased with the speed and efficient manner this was shipped, but due to age had a company install this unit for me. They wanted to know where I got unit for this old of an automobile and we're glad that everything they needed was right there to be installed. In this day and age it's nice to deal with such professional companies like etrailer.com.... 450511

Product was exactly as described. Only thing that i encountered different than the instructions listed ,, Stated match wiring color to color. Well it is hard to connect green to green for right turn signal when there is NO green wire for my right turn signal. It is actually tan. So color codes don't always match. The product works great and is used to supply power to my Jazzy hauler. Does what i purchased it for. Very happy with the product and excellent service from etrailer. 425143

Installed on a 2006 Honda Element. Found an etrailer video on youtube to help me with the wiring and everything was perfect. The device installed behind my left tail light, and I had to use a butt splice connector and some extra wire to lengthen the wire to reach the right turn signal. Even those steps were spelled out in the video. Great website and support. Would order again from etrailer. 580099

Converter replaced the original U-Haul unit that was installed with new hitch when my 2001 Toyota Tacoma was just purchased. I guess the old unit had an internal failure as the RH brake light quit working on my trailers. The new one works as it should and I hope to get another 16 years or so from it 457430

Installed easily. Wire colors were not the same as my car, but it wasn't hard to figure out what hooked to what. I would have given 5 stars had the four required tap connectors been included with the harness. Trailer lights and flashers worked just fine on the first attempt - didn't even need to change the turn signal relay to prevent high speed flashing. 279701

Do you have a question about this Wiring?


  • Wiring Harness Recommendation For A 2004 Ford Escape
  • The Upgraded Circuit Protected Tail Light Converter with 4-Pole Flat Trailer Connector part # 119178 is not ran directly to the vehicle's battery. There are 5 wires that you will need to connect in order to install this harness. The white wire is for the ground circuit. The brown wire is for the tail lights. The yellow wire is responsible for the left turn signal. The red wire is responsible for the stop lights and the green wire is for the right turn signal. You will attach each of these...

  • Trailer Wiring Harness for a 2004 Ford Escape without Factory Tow Package
  • I do have some recommendations for you but you cannot use wiring harness # C55255 unless the 2004 Ford Escape has the factory tow package. The issue is either the factory connector this harness plugs into won't be there or, if it is there, it won't be active and additional parts would be needed anyway. For models without the factory tow package you would use a hardwire harness such as # HM48925 or # 46255. I recommend # 46255 because it is a powered converter which takes the load off...

  • Recommended Trailer Wiring Harness for 2015 Chevy Impala Limited
  • I'm glad to hear your trailer hitch receiver installation went well. For your 2015 Chevy Impala Limited, I recommend the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 which has a max amperage of 5 amps on stop/turn lights and 7.5 amps on tail lights. This is a confirmed fit for your vehicle and will protect your factory wiring. The Hopkins # HM48925 will only put out a max amperage of 2.1 per circuit so that won't help. There are many that could work,...

  • High Capacity Trailer Wiring Converter for Trailers with A Lot of Lights
  • The highest rated converter box in terms of amperage capacity is # 119192. It is rated for 4.2 amps for brake and turn signal lights per side and 16 amps for running/tail lights. Since you are using LED lights though the power draw from those lights won't come close to the capacity of this system. This is a powered converter and it can be used on vehicles that have combined stop and turn signal lights. All you would do is ground the red wire with the white wire and use the green wire...

  • Will Curt Hitch and Drawbar fit a 2007 Toyota Saris?
  • The Curt Trailer Hitch Receiver # C11060 will fit your 2007 Toyota Yaris if it is a sedan and not a 3-door hatchback. The correct ball mount for this hitch is the Curt # C45521, for which you'd also need a pin and clip, # F-4. Keep in mind that using this hitch would require the use of Curt's support straps # 18050 for non-trailer loads or you would void the warranty. Should you have a hatchback, I highly recommend using the Draw-Tite # 24819. It will not require the use of...

  • Trailer Wiring Harness for a 1998 Toyota Tacoma
  • If you want to hardwire in a trailer connector to your 1998 Toyota Tacoma then you can use # HM48925. It is just more work though when you could use a harness that plugs in line with the vehicle tail light wiring such as # HM43315. But it is totally up to you. You should not have to have any sort of special flasher or load resistors for the unit to work. That sort of thing is only an issue on certain applications with LED lights on the vehicle side and almost never affects the trailer...

  • Best Towing Options for a 2005 KIA Amanti and Fleetwood Prowler Style Camper
  • While the tow capacity numbers appear to match up fairly close, the loaded weight of both your camper and vehicle need to be taken into consideration. After doing some research, I found that your Camper weighs in at a dry/empty weight of just under 2,000 lbs. Your KIA's tow capacity rating is in that same range. However, if you load any gear in your KIA's trunk along with any additional gear in your trailer, you will be above towing capacity. I would not recommend towing your Prowler...

  • Why Is Taillight Converter Needed for Trailer Wiring on 2005 Toyota 4Runner
  • The converter aspect of the trailer wiring for your 2005 Toyota 4Runner is not a voltage converter. Instead it converts the taillight signals to match what trailer wiring requires. Trailer stoplight and turn signals are carried on the same wire and some vehicles have the turn signals and the stoplights carried on two different circuits. That's where the converter of the part # HM48925 comes and changes the vehicles separate circuits to combined and allows the trailer taillights to function...

The Curt hitch is designed to fit up under the bumper and to bolt on to the frame of your vehicle. You will need to know what your vehicle's towing and tongue weight capacities are before installation. The Nissan 200SX has an approximate towing capacity of 1,000 lbs. The max tongue weight for your vehicle will be between 100-150 lbs. The max tongue weight...

  • Do I Need A Heavy Duty Flasher To Install A Wiring Harness On A 2004 Ford Escape
  • Neither the Hopkins Tail Light Converter Kit with 4-Pole Flat Trailer Connector part # HM48925 or the Upgraded Circuit Protected Tail Light Converter with 4-Pole Flat Trailer Connector part # 119178 will require you to use a heavy duty flasher while towing with your 2004 Ford Escape with or without the factory tow package. Each of the lighting circuits on the wiring harness has a 2.1 amp max draw, therefore this is not problematic for your factory wiring circuit. I will say that it will...

  • Recommended Fifth Wheel Trailer Hitch for 2004 Dodge Ram Pickup Towing a 7300 lbs. Trailer
  • With a 6 foot bed on your 2004 Dodge Ram you are definitely going to want to go with a sliding hitch. The Reese Titan # C16521 is a slider with 12 inches of travel. The sliding hitch will help with clearance when going around sharp turns. This hitch is rated for 16,000 lbs. which is plenty for the trailer you're looking at. The Custom Install Kit # RP50040-58 is what you'll need to install the hitch. This kit doesn't require any drilling and is much faster to use than the universal...

  • 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.

They are all hardwire options that require splicing into the vehicle tail light wires. But what you can do is use a circuit tester such as # 40376 or a meter if you have one to test the pins or the wires of that connector you found while someone sits in the vehicle to operate the lighting functions....

  • Troubleshooting Trailer Wiring on 1999 Chrysler Cirrus Where all 4-Way Pins Have Voltage
  • If all of the wires have voltage when the signal lights come on typically that is a sign of a shorted out converter box of the wiring part # HM48925. You can test this by checking for voltage on all of the wires leading into the box to see if the correct voltage is on the wires when the appropriate turn signal is applied and then check the output side of the box. Is correct on the input side then the box is shorted out. If not then it is wired wrong. Before you replace the harness...

  • I cannot be sure as to what the plug you have found is for but I can assure you it is not for a brake controller. The brake controller plug (if equipped) for a 2008 Dodge Ram is rectangular with four pins like the photo I have attached for you, there are no exceptions. If you just randomly look under the dash of your Ram, there are going to be several unused connectors.

However, this hitch only has a 1-1/4" receiver tube opening and since you plan to be towing a trailer then I highly recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 75659 because it has a 2" receiver tube opening. As you mentioned you will also need a trailer wiring harness and ball mount/hitch ball. For a trailer wiring harness I recommend the Hopkins Tail...

  • As long as the body lift doesn't interfere with any of the mounting points of the Curt # 13333 there won't be an issue. I've linked the installation instructions for you to take a look at. Since your truck is raised you may need a ball mount that is adjustable. The B&W Tow and Stow # BWTS10038B is a great option and includes two hitch balls. It flips over and stores under the hitch and out of the way when you're not towing. You use the locking hitch pin # BWTS51234 to keep it secure...

  • Running Lights and Turn Signal Not Working on One Side of Trailer
  • On the trailer side is the 5 indicating that it is a 5-Way flat connector or that it is a 4-Way with 5 wires? On a 5-Way flat the 5th pin is usually for an electric reverse lockout on a surge coupler so it would not have any effect on the lights. If it is a 4-Way with 5 wires then that is a wishbone harness which means that the running light pin has 2 wires, 1 for each side of the trailer, for running/tail lights. Since some of the lights are working and some are not it could just be...

Use # HM48925 for a 4-way trailer connector on the back of the Metro. For a hitch ball that fits the trailer hitch receiver use # 19258 for a 2 inch or # 19256 for a 1-7/8 inch.

The maximum trailer weight capacity of this hitch cannot be increased by using a class II ball mount like the Curt Class II Euro Style Drawbar part # C45572 sadly.
