Yes, the 10-16 Buick LaCrosse CURT 4-flat Plug and Play Trailer Wiring (Part #CTW197) is designed to fit the 2010-2016 Buick LaCrosse.
The 10-16 Buick LaCrosse CURT 4-flat Plug and Play Trailer Wiring (Part #CTW197) fits the following vehicles: 2010-2016 Buick LaCrosse. Always verify your specific year, make, and model before ordering.
The 10-16 Buick LaCrosse CURT 4-flat Plug and Play Trailer Wiring (Part #CTW197) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the Curt 56098 is designed for Buick LaCrosse passenger cars. The harness connects to the vehicle's taillight wiring and includes connectors that match the factory taillight housing connectors.
The Curt 56098 is a custom wiring harness that provides trailer lighting connections for a Buick LaCrosse. It taps into the vehicle's taillight circuits and includes a converter box to manage signal and running light circuits for trailer use.
You will need a Phillips screwdriver, flat blade screwdriver, and panel trim removal tool. These are the only tools required for installation.
The harness includes: custom wiring harness with yellow and green wire ends, white ground wire with ring terminal, black power wire, black converter box, provided screw for grounding, double-sided tape, cable ties, and a 4-flat dust cover.
The manual does not explicitly state whether the battery must be disconnected. However, since the installation involves working with the vehicle's electrical system and taillight connectors, it is recommended to consult the vehicle owner's manual or contact the vehicle manufacturer for safety guidance.
Open the tailgate and remove the scuff panel by pulling out at the bottom and then up. Remove the plastic fasteners securing the felt trunk liner on both sides. Remove the four plastic wing nuts securing each taillight assembly. The taillight assembly will then lift away to reveal the vehicle's taillight wiring harness connectors.
The custom wiring harness end with the yellow wire connects at the driver side taillight, and the end with the green wire connects at the passenger side taillight. Both ends insert between the separated vehicle taillight connectors, with the locking tabs fully engaged.
Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated vehicle taillight connectors. Ensure the connectors are fully inserted and the locking tabs are in place. Take care not to damage the locking tabs during insertion.
Drilling may be required for the ground wire connection. You can either locate an existing screw with nut in the vehicle frame to secure the white ground wire's ring terminal, or drill a 3/32" pilot hole if no suitable existing fastener is available. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The pilot hole size is 3/32". This hole is drilled only if no existing screw with nut is available in the vehicle frame near the taillight connector.
The battery connection must be fuse-protected with a maximum of 10 amps. Exceeding this rating can cause loss of warranty, overheating, and potential fire. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower.
The black converter box should be adhered to a flat spot inside the vehicle near the taillight using the provided double-sided tape. The location should be convenient and secure.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Test for proper function by using a test light or by connecting a properly wired trailer. All installation steps must be followed to ensure the wiring harness functions properly.
The scuff panel is removed to access the taillight area. It should be reinstalled at the end of the installation (Step 10). When removing it, take care not to damage the alignment tabs on the back, as these are needed for proper reinstallation.
Yes, the plastic wing nuts that secure each taillight assembly should be reused. They are removed during installation to access the taillight connectors and must be reinstalled when reassembling the taillight housings.
Remove the plastic fasteners securing the felt trunk liner on both sides of the vehicle and pull the liner back to access the taillight assemblies. The liner should be reinstalled after the wiring harness installation is complete.
Before drilling the 3/32" pilot hole for the ground wire screw, check for miscellaneous items that may be hidden behind or under any surface. This precaution avoids damage to hidden components and personal injury.
The area where the white ground wire is secured should be free of rust, dirt, and paint. This ensures a proper electrical connection. The ring terminal should be secured using the provided screw to either an existing screw with nut in the vehicle frame or to a 3/32" pilot hole you drill.
Install the provided 4-flat dust cover on the connector to help prevent corrosion. This should be done during the final reassembly step.
