Installation

This custom-fit T-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. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Once installation is complete, the 4-way 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.


Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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 the trailer. This 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.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Trailer wiring installed with ease and worked as expected.
The hitch was installed in the stated amount of time and operated as designed. Hauled lite weight boat trailer 170 miles with out a problem. Lighting worked as intended.

it has performed as expected each time that I have used it. Easy install hitch and wiring.



by:

Too complicated. A wiring harness that links to a rear tail light is much simpler. Aside from that the wiring works as it's supposed to, but the connector is stored in the trunk of the car until needed.
The Cort hitch works fine on the Buick Lacrosse, but will drag when entering or leaving a steep driveway. I don't think Buick intended for this car to be fitted with a hitch.



by:

Went together well. Running the power from the battery was a pain. If I had a lift, it would have been easier.

I am very satisfied with my trailer hitch and wiring purchased from etrailer for my 2011 Buick LaCrosse.



by:

The trailer hitch and electrical kit I ordered arrived in a timely manner. The install was pretty easy and although I have not used it, seems to be a great buy. Thank you for the instructional videos!



by:

Worked as designed. I do a lot of my clients work with parts and supplies from etrailer. Great company and great products. Pay attention to the install video. They warn you about how tight the application is fishing up the harness. The video gave me the heads up and the trick to make it work. Thanks again.

2015 Buick LaCrosse

The product for the LaCross came complete with fused block for power to the turn signal module. Our trailer (6 x 8) is equipped with LED lighting for better function and visibility.

Highly recommend the product, but the service and follow up from etrailer is the best on the web.

Thank you!



by:

Outstanding, the ease of installing and adaptation to design of car was superb, a true credit to your Engineering design staff. My son and I order all of our needs from etrailer, we have never had any issues and the designs are outstanding.

Great product. I installed this on a 2015 Buick Lacrosse (Dual exhaust). The dual exhaust did not effect installation. The reason I gave 4 stars is because it was very very very hard to feed the connector that plugs into the rear car lights between the car and the body. I had to pry the body of the car away with a screw driver to allow enough room to sneak the connector up. Just pointing it out, does not make the installation immpossible, just a bit harder. I recommend this product for a 2015 Buick Lacrosse because that is the only vehicle installation I have done.

Received hitch and wire harness a day ahead of schedule, packed in same box and arrived undamaged.



by:
2011 Buick LaCrosse

I was able to install this myself due to simple, clear instructions. It's components are made up of quality materials, are well packaged, and one year later it still functions as intended.

I have no problem endorsing this and would definitely buy again. It turned a headache into a manageable task!

  • Tips for Routing a Power Wire from the Battery to Trunk for Trailer Wiring on a 2011 Buick Lacrosse
    There are a few methods that people use when they need to run a power wire from the vehicle battery to the rear of the vehicle. One method involves routing the wire as much as possible through the frame. What you would need to do first is determine if the frame has a hole in which a wire can be run and if there is space enough for it. You would need a long rigid and skinny object, like a coat hanger to run through the frame, tie off the wire to it, and then pull it back through. This...

  • Curt Trailer Hitch Receiver Compatibility With a 2015 Buick LaCrosse With Dual Exhaust
    You will not have any issues mounting the Curt Trailer Hitch Receiver # C12115 on your 2015 Buick LaCrosse with the dual exhaust. Since this receiver fits a large selection of Buick, Chevrolet and Cadillac vehicles the installation notes will cover all the different vehicles but some steps like lowering the exhaust will not always be necessary. For your LaCrosse I do not see any need to lower the exhaust. Curt recommends using their Cam Buckle Stabilizing Strap # 18050 for any hitch mounted...

  • Will CURT Trailer Hitch Receiver # C12115 Fit 2012 Buick LaCrosse
    From the information I was able to obtain, the item you selected, CURT Trailer Hitch, part # C12115, will fit your 2012 Buick Lacrosse. The wiring you referenced, CURT Custom Fit Vehicle Wiring, part # 56098, is the correct wiring kit for your vehicle. For a ball mount use # C45017. To complete your towing setup, you will either need a 1-7/8 inch hitch ball, part # 19256, or 2 inch hitch ball, part # 19258, depending on the size of your trailer coupler.

  • Trailer Taillight Wiring Harness for 2011 Saab 9-5
    It's possible that the Curt # 56098 for the 2011 Buick LaCrosse would work on your Saab 9-5, but Curt hasn't tested it. In photos, it appears that the taillight assemblies on both vehicles are pretty similar. I'd recommend accessing the connection points where the taillight assemblies plug into the vehcile's taillight harness as shown in the linked video. Compare the connectors for the # 56098 (see photo) to those on your vehicle. If they're identical, the Curt # 56098 would likely work...

  • Trailer Hitch and Bike Rack Recommendations for a 2011 Buick Lacrosse CXS
    Some companies prefer to be more cautious with their product ratings than others. Curt requires the use of stabilization straps, # 18050, on all of their Class I and II trailer hitches, regardless of tongue weight capacity, in accordance with their warranty requirements. The Draw-Tite and Hidden Hitch trailer hitches do not require a strap, but a strap can still be used and would not be a bad idea in any application using a larger bike rack. I would recommend the Curt Trailer Hitch, #...

  • Trailer Hitch and Wiring for a 2011 Buick LaCrosse CXL
    Curt trailer hitch # C12115 has a capacity of 3,500 pounds gross trailer weight and 350 pounds tongue weight. But I checked the owner's manual online for your 2011 Buick LaCrosse and found that it has a towing capacity of 1,000 pounds so you are limited to that even though the hitch is rated higher. If the gross trailer weight is under 1,000 pounds then you can pull it with your LaCrosse. A 17 foot boat and trailer is likely heavier than that though. The recommended ball mount for this...

  • Trailer Hitch For A 2013 Buick Lacrosse
    Hello Gregg. We do offer a trailer hitch for your 2013 Buick Lacrosse, the Curt Trailer Hitch Receiver # C12115. This is a class 2 hitch, it has a 1-1/4" receiver and is rated for towing up to 3,500 lbs or 350 lbs of tongue weight. So, more than enough for a light boat and trailer. I also recommend that you get the Curt T-Connector # 56098 which will definitely be the most convenient wiring option for your Buick. You will also need a ball mount such as part # 36065 as well as a 1-7/8" ball...

  • Trailer Hitch Receiver for a 2015 Buick Lacrosse FWD
    The Draw-Tite Class II # 36538 or Curt # C12115 are a custom fit for your 2015 Buick Lacrosse FWD. The specific Draw-Tite hitch receiver you referenced will not fit your 2015 Buick Lacrosse FWD. With either option, if you will be towing a trailer you will additionally need a ball mount. I recommend # 36061 which comes with the pin and clip. You will still need a hitch ball like # 19258 for a 2 inch coupler or # 19257 for a 1-7/8 inch coupler. Then the wiring you will need for your hitch...
