Do I Need a Tail Light Converter?
Some vehicles operate on a 3-wire system, wherein the brake signal and the turn signals run on separate wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) But most trailers run on a 2-wire system, which means the brake and turn signals travel along a single wire. You'll notice that, on your trailer, the brake light will flash for the turn signals.
If your vehicle operates on a 3-wire system, it will need to be converted so it will be compatible with the wiring system of your trailer. This is where a tail light converter comes into play. This converter lets you combine the brake and turn signal functions of your vehicle so they run on a single wire to properly activate your trailer's tail lights.
Converter Wiring Configuration
| Wire Color | Wire Function |
|---|---|
| Green | Right turn |
| Brown | Tail lights and parking lights |
| Red | Brakes |
| White | Ground |
| Yellow | Left turn |
Tail Light Converter Installation
To begin the installation, use a circuit tester (sold separately) to double-check the function of each wire on your vehicle's tail light wiring harness. The color/function of the splice-in wires on this converter may not match the color/function of those on your vehicle, so you'll want to be sure to check all of the wire functions first. 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.
Use double-sided tape to stick the converter box to a flat surface inside your vehicle near the tail lights. It's helpful to clean the surface first so the tape can adhere fully.
Find a raw, unpainted metal surface to use as a grounding point and secure the white ground wire with a self-tapping screw (sold separately). Cleaning the surface prior to securing the white wire will ensure the converter is fully grounded. Finally, secure the converter wires to your vehicle using cable ties (sold separately).
Quick Tips:
- Butt connectors - especially heat-shrink ones - provide the most secure, longest-lasting connection, so we'd recommend you grab a few for this installation.
- 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.

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.

by: Gordon08/04/2019
This Hopkins light converter works great, is small and simple. I used it to create a converter cable from a Euro 13-pin plug to a US 4-pin flat plug. Works great and is small enough to keep the cable compact.

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.

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.

The unit is still performing flawlessly. I highly recommend where this particular unit is suitable.

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....

2006 Honda Element
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.

Not worth the money. It does do the job, but u're better off searching for one that has the splicing connectors for the same or less .

We do not have any quick connects for your 2001 VW Jetta Sedan TDI unfortunately.
by: Eric11/05/2017
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

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.

etrailer is the real deal. The hitch and inverter package I purchased is high quality. heavy duty and built to last. Shipping was free and speedy during this time of so many slow downs.
I would definitely recommend to others. Thnx!

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

Installed fairly easy. Fit was exact. The carriage bolts for this frame need to be an inch shorter. Would have been nice to include a splice kit for the electrical. Installer should have adequate mechanical ability. Good product. Arrived promptly. Would shop here again.
by: Justinm03/14/2020
Took all of 40 minutes to install and wire up. My suggestion is to make sure to have a deep well 3/4 inch socket and an impact. It will save a bunch of time. Also get quick splices for easy wiring of your harness. Other than that pretty east stuff.

I verified the signals coming from my motorcycle and the colors didn't match up to the standards but doing that and using solder pellet shrink connectors made it a neat and easy install.

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 any stabilization...

- Draw-Tite Hitch Ground Clearance on 2012 Hyundai Accent With the Draw-Tite Sportframe Trailer Hitch Receiver # 24884 you will have approximately 8" of clearance to the bottom of the hitch on your 2012 Hyundai Accent. Please be aware that this is an estimate as if your particular vehicle may have larger or smaller diameter tires. Also the amount of weight that is being carried inside your Accent will change your hitch height as well as aged suspensions may sag a bit due to age.

For a basic one you can use # HM48925. You can then cut off the 4-Way end of this harness after it is installed and attach the wires to the light bar wires. On the HM48925 the white wire is ground, brown is running lights, yellow is left turn and brake lights and green is right turn and brake lights. The HM48925 will not have a reverse light function...

view full answer... - Trailer Wiring Harness that Fits 1994 Ford AerostarThe only trailer wiring harness we offer for the 1994 Ford Aerostar is the Hopkins part # HM48925 that you referenced.

view full answer... - Trailer Brake Lights Not Working when Towing with a 1992 Toyota CamryYou are on the right track with the converter. The reason your brake lights on your trailer aren't currently working is that the brake light and the turn signal are two separate circuits on your vehicle. On your trailer, these two functions share the same circuit, so a taillight converter is needed to combine the brake and the turn signals on to the same circuit. The wiring harness you mention, the Converter with 4 pole end, part # HM48925 might work for you, but the manufacturer recommeds...
