Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Circuit-protected converter guards against shorts.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Includes circuit-protected tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Provides protection against electrical shorts and overloads
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 4.2 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.


T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


Circuit-Protected Tail Light Converter

A tail light converter is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

Super easy installation, video instructions were most helpful,

one happy customer



by:
Saturn Vue

Instructions were complete and installation was a breeze. Delivered quickly and fit our Vue perfectly.



by:

The trailer wiring harness was exactly as advertised. Works great!



by:

The product fit and worked just fine. A nice addition would be to add a cd to yhe kit with the video that's on your web page.



by:
2005 Saturn Vue

The harness went in exactly as expected and works perfectly. The wire lengths were good and the instruction were clear. Some disassembly of the vehicle was necessary, but no permanent modifications were needed.



by:

Should have watched the video before trying to do this by the written directions. I tried with the written directions and figured it out but went back to the video and acutally did it right. Make sure to watch the video.

I bought the trailer hitch and wiring harness for my 2007 Saturn Vue.
The service I got was excellent. The products were in excellent condition.

2006 Saturn Vue

Installation went well with the very adequate instructions.



by:

Easy to install, used coat hanger to pull the plugs down and up and did not need to take the fender well apart.



by:

I have no auto repair experience and I had no problem installing the wiring kit.



by:

Wiring harness was easy to install with those factory connectors. A+++



by:

Quality product and very useful video on installation. Thank you !



by:

You guys and girls are fantastic. Great service, nice people with a delivery that far exceeded my expectations.
All I can say is WOW. I would gladly refer my friends to eTrailer.



by:

I found this through YouTube, excellent! From now on, I don't go to the store, I go to etrailer.com. The item came in three days, perfect for my weekend project.



by:
2006 Saturn Vue

Kit is exactly like the picture and vids, easy as pie to install. Like everyone has stated, the wire to fish through is too short, needs to be longer but I guess they need to save costs lol. If you expand and flatten the wire completely straight, its just long to reach through.



by:
Saturn Vue

The video made it easy. Popped a few of the wheel well "buttons" out and fed the wiring through the taillight assemblies. You can tuck the wiring up in the fascia or tie to the hitch frame, either way you really won't see it. We just hooked up the ground to the the quarter panel retaining bolt since it was right there anyway. No need to drill a hole in your vehicle. Tested the lights once it was all set up, no problems on either the Vue or the trailer.



by:
2015 Saturn Vue

I recently purchased the 118418 T-connector for my Saturn Vue to haul a Scout Trailer. Watched the video once and had this installed in 15 minutes. Super simple to install and use. Since I have a Reese tubular hitch, I had to buy an adapter to mount the plug in an odd place, but the connector itself works and that is all I need it to do.
E-trailer made it extremely simple to install a trailer light hook-up, in fact, I will be ordering another one soon for another vehicle and will have my 13 year old son install it.



by:

Our order included everything that we needed. It arrived ahead of schedule and included clear written instructions. The online videos were extremely helpful as well. I highly recommend etrailer.com to anyone looking to install a trailer hitch. It makes it easy even for people with no automotive experience. Great job!!!



by:
2004 Saturn Vue

I've had a trailer hitch for about 3 yrs now but nobody had a quick connect wiring harness till I found this one. I didn't follow the directions to an exact "T" because I wanted my 4-flat plug to stay inside the car unless I'm hauling somthing. But I had the whole thing installed in about 20 mins. Best investment I've made. I'm trailering my new motorcycle next week. At least now I won't have to borrow trucks and such. I can go buy my own trailer. Worth the extra $ for quick connect. Solid product

  • Trailer Wiring Harness Recommendation for a 2005 Saturn Vue
    The recommended trailer wiring harnesses for your 2005 Saturn Vue are ones with converter boxes like the part # 118418. That being said our installer was able to find a way to wire in the part # 18002 to a 2004 Vue similar to yours. This isn't the ideal solution, but it would work if you used the install video as a guide. I attached install videos for both harnesses for you to check out.

  • Trailer Hitch, Wiring and Brake Controller Recommendation for 2005 Saturn Vue
    If the goal is to tow a trailer with your 2005 Saturn Vue I have a better setup for you to consider. For a trailer hitch the etrailer part # e98865 has great capacities and since it's a 2-inch hitch it will give you the best options for future accessories and ball mounts. For trailer wiring the Tekonsha brand is the most reliable so for your vehicle the best option would be the # 118418. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller....

  • Trailer Hitch and Wiring for a 2007 Saturn Vue
    Actually, if you were to try to install Curt hitch # C19101 it would require a lot more work than the custom fit hitches for your 2007 Saturn Vue. You would have to access the metal bumper beam which would require removal of the rear fascia. Then once you get that removed it is possible, even likely, that the hitch will not fit. Installation of a custom hitch such as # 13591 is much easier as you can see in the video I have linked showing an example installation. I have also included a...

  • Trailer Wiring Harness for a 2004 Saturn Vue
    The 2004 Saturn Vue used in the video, linked for reference, for wiring harness # 18002 has a factory tow package wire bundle. The factory tow package wire bundle already has the turn signal and brake light signals combined to wire in a 4-Way directly. No converter is needed. Otherwise you would use wiring harness # 118418 which does have a converter to combine the separate signals.

  • Recommended Trailer Wiring for 5x10 Trailer with 4-Way Trailer Connector
    If you have a 4-way trailer connector like # 118418 then I recommend using a wishbone harness to wire your trailer. The 20 Ft 4-Way Trailer Wiring Harness - Wishbone Style - 30" Ground # A20WB is my recommendation for your wiring because it will allow you to run 2 wired to each side. You will run the brown and yellow to the driver's side, and the other brown and green wire to the passenger side. The white wire will get connected to the trailer frame as a ground. The brown wires on each...

  • If there is a Short Circuit Will Curt Converter Box Blow or Just the Affected Circuit
    Normally when there is a short circuit it will blow the converter box no matter what the brand is. But sometimes it will only affect the one function that shorted like what you have experienced. It could go either way but regardless of what does happen you would need to replace the converter to fix the issue. We do have the plug in style T-connector # 118418 that you can use instead of a hardwire harness if you hare interested. I have linked instructions and a video for you to view. You...

  • Adding a 7-Way Trailer Connector to a 2006 Saturn Vue
    In order to add a 7-Way trailer connector your Saturn Vue you will first have to install a 4-Way using # 118418. Then to add a 7-Way you have 2 options. If all you want is for the lights to work on the trailer when you tow it with the Vue then you would need # 37185. You would ground the white wire and the other wires can be capped off and stowed out of the way. If you want all the functions of the 7-Way to work you would install the 4-Way but use # ETBC7 to add the 7-Way. If the trailer...

  • Recommended Trailer Hitch for 2006 Saturn Vue
    The difference is that the 2006 Saturn Vue Red Line models require noticeable rear fascia trimming when installing a trailer hitch. The Red Line models also have a lower suspension. For either model I recommend a Class III trailer hitch like the Curt hitch, # 13591, because it has a higher capacity and the 2 inch receiver is compatible with more accessories. I have included a video of this hitch being installed on a similar vehicle. To complete your towing package I recommend Ball Mount...

At the 3 minute and 16 second mark, our installer connects the Blue brake light wire from the Saturn Vue to the Red brake light wire from the trailer wiring harness.

    For your 2006 Saab 9-3 the DaLan part number 247326 you referenced is the correct part number and is the same as part number 11326 from Curt manufacturing on our site. The wiring does not come with the hitch. Your vehicle will need to be hardwired to provide an electrical trailer connector. I would recommend the # 119179KIT to wire your vehicle so that you have all of the wiring, hardware and inline fuse needed to complete the installation.

  • 4-Way Trailer Wiring Harness Recommendation for a 2006 Saturn Vue
    Since your 2006 Saturn Vue has separate turn signal circuits from the brake lights you would not be able to hardwire a 4-way directly to the taillights like with the part # 18004 that you referenced. Instead you would need a harness that has a converter built into it so that the circuits are adapted to what a 4-way requires. For that we have the part # 118418 which is a confirmed fit and would work well. This plugs in line with your vehicle taillight harnesses and does not require any...

  • Recommended Trailer Hitch And Wiring For A 2004 Saturn Vue Redline
    Hi Troy, For a Saturn Vue Redline you'll need the etrailer Trailer Hitch Receiver # e98865. This is confirmed to fit your Redline model but will require a decent amount of trimming on the rear fascia in order to fit. If you're planning on towing a trailer then you'll want to pick up the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118418 as well.

  • Will Tekonsha Universal Wiring Harness Fit a 2006 Saturn Vue
    The Upgraded Circuit Protected Tail Light Converter Hardwire Kit # 119178KIT is technically a universal kit so it will indeed fit your 2006 Saturn Vue. With that being said, the T-One # 118418 is actually a plug and play style that tees in behind your tail lights and would be much easier to install so I recommend going with this instead. I have attached an installation video of this kit as well for you to compare to the universal kit. If you don't already have a trailer hitch then I...

    The Curt trailer hitch # 13591 does fit a regular 2005 Saturn Vue. And it fits the Red Line like you said. So it will work for your 2005 Vue. Curt, Draw-Tite, and Hidden Hitch all make good hitches so the preference is yours. I have linked a video showing installation of the Curt hitch for you.

If you need a 4-way flat connector you could use the Upgraded Circuit Protected Modulite with 4 Pole Harness and Hardwire Kit, part # 118418, which will include all wiring and connectors to complete the wiring along with instructions.

  • Where to Mount Converter Box When Installing Trailer Wiring for 2006 Saturn Vue
    With the install of the Curt trailer wiring harness part # C56018 that you referenced Curt recommends finding a flat spot inside the vehicle near the taillight to adhere the box to in step 6. When we had the chance to install the similar Tekonsha kit part # 118418 on a 2006 Saturn Vue like yours we mounted the box in the driver side rear taillight area. If you check out the 1:00 mark of the video you'll see our installer mention this although it's not shown.

  • Cargo Carrying Options For 2007 Saturn Vue With Naked Roof

My best recommendation is to install a trailer hitch like the etrailer Trailer Hitch, part # e98865. This is a Class lll hitch and it has a 2-inch receiver opening. Installing a trailer hitch will give you many options for carrying items like bike racks or cargo carriers. You can also tow a trailer behind your Vue.

  • Do Torque Specs for Installation of a Trailer Hitch on a 2003 Saturn Vue have to be Followed
    On a 2993 Saturn Vue you should be fishwiring in 1/2 inch bolts and blocks through the frame and to the bolt holes on top of the hitch as indicate in step 5. The bolts that get fishwired in are 1/2 inch carriage bolts. It is important to get the bolts to the proper torque spec. If they are too tight you can damage the hitch and vehicle. If they are not tight enough you could loose the hitch. Most auto parts stores will loan out tools. You will need a torque wrench that goes up to at least...

All you would need to convert the 4-way of this harness to a 5-way to activate the reverse lockout of your trailer is a part # 20036. You will need to tap into the reverse light circuit of your Vue using the included quick-splice. I attached an installation video for the # 20036 for you to check out also.

The wiring for a 2008 would be part # C56026 or for a 2005 # 118418. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900.
