4-Way Trailer Connector Installation
Because the color/function of the wires on this connector may not match the color/function of those on your vehicle, be sure to use the included tester to double check the function of each wire on your vehicle's tail light wiring harness before installing this connector. Once you've figured out the functions of your vehicle's wiring, use the included quick-splice connectors to connect the corresponding wires on the trailer connector. Quick-splices, or "wire taps," offer a quick way to make connections without you having to strip and twist wires. Just place the wires in it and snap the cover down.
The number 1 reason trailer wiring comes up faulty is a bad ground, so make sure your ground wire has a solid and clean connection to metal. To make this connection, you'll need a self-tapping screw and a ring terminal (sold separately).
Wiring Configuration
| Wire Color | Wire Function |
|---|---|
| Green | Right turn and brake light |
| Brown | Tail lights and running lights |
| White | Ground |
| Yellow | Left turn and brake light |
Quick Tips:
We install a lot of wiring harness around here, so we thought we'd share a few tips we've picked up over the years:
- Butt connectors - especially heat-shrink ones - provide the most secure, longest-lasting connection, so we'd recommend you grab a few and swap them out for the quick-splices in this kit.
- 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.

This harness worked great for my Corvet te.
by: Michael11/07/2022
Worked great for 6 mo. Ish. I’ve had the right side wire become loose/break so occasionally the right side will randomly choose to quit working but (at least for me) that’s not a huge deal with how little I use my trailer. solid purchase overall.

I have contacted the manufacturer and the have suggested that the wiring harness should be checked for a good connection, it sounds like the harness may not be connected correctly.
by: Brian03/14/2019
First thing I noticed were the online videos that can be saved to a file. nice! also noticed the instructions for assembly of the tow bar was small and difficult to read, (my mechanic was crying throughout the installation) There were no instructions on the wiring kit installation, even a photo of the wire to wire color placement would have helped, but my mechanic went on line and got the photo from an outside source - thus the 4 stars, not five. - other than that it worked out very well, the products are solid, well made, and superbly engineered. everything was inside! thanks !

Took me almost a year to actually get to installing this on the van, but wanting to use the trailer was a strong motivator. Its just a basic wiring set with quick connect clips in a bag. The fact that I was installing this on an extended camper version of the van this was designed for complicated the install, but "fortunately" there were enough rust holes that I could drill where I need to drill. Wires were long enough for the job (exactly the length needed) and the clips came pre-filled with silicone grease. Nice. Came with no instructions, but the on-line installation video is *excellent* and guided me thru the entire process. Overall, it was a convenient way to buy and install a wiring harness on my older van. Only two minor complaints:
* Did NOT include a weather-proof cap for the plug, which hangs outside by the hitch. I took the one included with the wiring kit for my Suburu (from etrailer) since that plug is stored inside the vehicle.
* The 12v circuit tester did NOT work. Fortunately I had my own tester.

1984 Jeep CJ-7
I got a 4-wire harness to connect my jeep to a utility trailer. The harness worked perfectly.
The connectors were good--surprisingly, they were stuffed with noncorroding gel so that the jeep's wires are protected. There were no specific instructions for the hookup, but simply removing the taillight lenses showed which color wires to splice.
The supplied tester failed to function, but that wasn't a problem at all--I didn't really wish to poke additional holes into the wires anyway.
Took a half hour to complete.

by: Matt F03/09/2020
Product as described and very easy to install. In my case it didn't work, because the original wiring on my truck apparently is bad and I couldn't figure out what was faulty, so I ended up getting another harness that plugs into existing tail light harness, which worked great.

1998 Chevrolet Blazer
Only thing that needed to be changed was wire connectors. Type included with the plug are easy to install (no insulation stripping, just clamp) but are not reliable. Throw those away and use standard crimp butt splices. Plenty of wire included, so I cut to more convenient length, spliced, and taped 8 inches on both side of splice. Tester is a nice touch, save in your tool box after installation.

by: Gene08/15/2014
Your product was easy to install and works fine. However, one thing that I think would be a good idea, would be to include a set of installation instructions with the product. I didn't know that the metal tabs on the connectors had to be pushed all the way down before snapping the plastic hinge over the top of the tab. A friend of mine informed me of that.

- Parts Needed to Add a 4-way Wiring Harness to a 2018 Jayco North Point 5th Wheel TrailerI do have an option for you, but it will involve splicing into some wires. There is not a plug-n-play option available for your 2018 Jayco North Point 5th wheel. - 4-Pole Hardwire Kit with Circuit Tester # 18252 which has Quick-splice connectors to ease installation. We also have bonded 4 Wire # 16-4B-1 sold by the foot if you need more wire length. If you need to add additional wire you'll need some 16-14 Gauge Butt Connector # 05731-5 to connect the wires.
view full answer... - Brake Controller and Install Wiring Recommendation for 1971 Ford F-250You will need to start with a 4-way (if you do not have one). For that you would want the # 18252. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake...

If your truck currently has a factory installed 7-way then you can plug the # 22292 wiring adapter into the wiring harness located in the dash of your truck and then, after routing the other end of the wiring adapter under the dash, you can plug it into the brake controller. If your truck does...

If your F-150 did not come with a factory 7-way connector you will need to use the # ETBC7 if your truck has a 4-way connector already installed, or the 4 Pole # 18252 and # ETBC7 if your truck did not come with a factory trailer connector.

view full answer... - Brake and Turn Lights Not Working when Trailer is Plugged into the 4-Way on a 2009 Saturn SkyI would not recommend to replace any of the relays on the 2009 Saturn Sky. If you are having a wiring problem and the relay is activating, it is doing that to protect your vehicles wiring system. You do not want to change the relay and allow more current to get to your wiring system, which could cause major damage. The relay is doing what it was designed for. It sounds like it is a ground issue with the wiring on your vehicle. You will want to make sure that the white (ground) wire is...
view full answer... - Installing Trailer Wiring Harness on a 2004 Ford FocusIt looks like you have purchased wiring harness # 18252 which is correct for a 2004 Ford Focus. This vehicle does not require a converter because it has what is called a combined lighting system. This means the brake lights and turn signals are combined onto one circuit. This is the same way most trailers are wired. You will use the included circuit tester to tech the wires behind the tail lights on the vehicle. Starting on the drivers side, where you will be attaching 3 of the wires,...
view full answer... - Trailer Connector for Golf CartHow you'd proceed will depend on how the existing taillights on the golf cart are wired. If it's a combined wiring system, where the turn signal and brake lamp are carried on the same circuit you can simply splice a 4 pole connector in using # 18252. Rather than using the quick splice connectors, I'd recommend soldering the connections and protecting them with heat shrink tubing like # DW05451. If you don't have a soldering iron, we offer a handy cordless model as part # PTW2000. If your...

The typical locations for this connection point are near the spare tire and also on the drivers side behind the rear tire on the frame rail. This connector will most likely have a dust cover on it and you should be able to remove the cover and the zip ties holding this to the frame and plug it directly into the connector on the rear of the Curt Trailer connector...

If it's equipped with a 7-way trailer connector, it'll likely be prewired for a brake controller. On the truck cab/chassis, the brake controller connector which is gray in color would typically be located above the driver's right knee, under the dash. On the van chassis, it would usually be found to the left of the steering column. If the connector is present, it should be a plug and play installation. For...
view full answer... - Why do the Side View Mirror Turn Signals Activate When Applying the Brakes on a 2005 Ford RangerIt sounds like your after market turn signals might be tapped into the wrong turn signal circuit on your 2005 Ford Ranger. Your after market turn signals should be wired into the front turn signal circuits coming from near your headlights, which does not contain a brake signal. If you have the wires spliced into the rear turn signals, then that will explain your problem. The rear turn signal circuit on your truck is combined with the brake signal. The lights on your mirrors will pick...

Connecting 4-way wires to the diode kit you have with something like the part # 18252 would accomplish this.

This will require a working 4-way flat and for that use the 4-Pole Hardwire Kit with Circuit Tester part # 18252 which you can use to pickup your turn, brake and running light signals. I have linked a video on each of these for you to check out.

If you wire the 4-pole, part # 18252 to the correct wires you will get the brake signal on your trailer. On the Draw-Tite Wiring, part # 18252, you will need to use a circuit tester # PTW2993 to connect to the correct wire function. On part # 18252 connect the White wire to a clean metal surface for ground, Brown to the running light circuit, Yellow to left turn and brake, and Green...

First you will need the brake controller with wiring harness, item # 90885-3035-P. The wiring harness will plug into the brake controller and into the connector under the dash. Finally, you will need the Adapter 4 Pole to 7 Pole and 4 Pole, item # 37185, which will plug into your existing 4-Way connector. If you do not have a factory 4-Way one will need to...
view full answer... - Connecting Curt Auxiliary Light to Running Light Circuit of VehicleSince the Curt Auxiliary LED Indicator Light part # C53201 uses a 4-way trailer connector you'd want to use the 4-way install kit part # 18252 to tap into the running light circuit of your vehicle. You'd ground the white wire and then use the quick splice that comes with it to connect the brown wire of the 4-way to the running light circuit power wire.

You have standard 4-way trailer wiring colors correct but your trailer may use different colors so you'd basically just have to check out the wiring that runs to all the lights of your trailer assemblies so that use the correct circuits. The # 18252 comes with a circuit tester to so you can test the wiring too and be sure.

This harness includes a circuit tester to help determine the wire functions on your Jeep and find the correct wires. If you don't already have a trailer hitch receiver on the Jeep the best option we carry is the Curt # 13657. It's a Class III hitch which is gives you a higher towing capacity as well as a larger...
view full answer... - Troubleshooting Low Brake Output Brake Voltage on a 2007 NU WA HitchHiker 34 5th WheelIt sounds like there is something wrong on the brake output circuit of your trailer. The reason I say that is because you have 12 volts at the connector on your 2008 Ford F350 brake controller but somehow only 3 volts are making it to the brake assemblies. Since the brake assemblies are brand new that eliminates them from being the problem. What I would do is start at the back of the connector with a voltmeter like 7-Function Digital Multimeter # PT89ZR and test the circuit for 12 volts...
