The GMC Acadia is a mid-sized crossover SUV sporting different features to benefit various drivers and passengers. Outdoor enthusiasts may choose to bring this vehicle as a secondary vehicle for their camping trips. But is it possible to flat-tow a GMC Acadia? If so, how can you do it? We researched for you to answer these questions, and here’s what we found.
Most GMC Acadia models throughout the years aren’t flat towable. Owners of specific Acadia models, like the 2007 and 2018 versions of the vehicle, can flat tow these automobiles. If flat towing isn’t an option, it might be possible to dinghy or dolly tow the Acadia behind an RV or motorhome. The steps to achieve this setup are:
- Put the Acadia’s transmission to Park (P) and turn its ignition to the "LOCK/OFF" position.
- Place the Acadia behind the towing vehicle.
- Activate the Acadia’s ACC/ACCESSORY mode and shift it to Neutral (N).
- Remove the correct fuses from the engine’s fuse block and store those parts to put them out of harm’s way.
- Release the GMC Acadia’s parking brake.

How Do You Install A Tow Bar Wire?
Before proceeding with the installation, it’s important to know how a tow bar wiring kit works. It functions by connecting the electronics on both the towing and towed vehicles to help secure the vehicle-pulling assembly. Some tow bar wires can also activate the pulled vehicle’s brake system to ensure its tires don’t roll when stopping the towing vehicle.
Plus, ensure that the tow bar wiring kit is compatible with both the towing and towed vehicles. However, some wiring systems have universal designs that should fit most vehicle-pulling setups.
Check out this universal wiring kit on Amazon.
After taking note of those pieces of information and assuming that you already bought a compatible kit, follow these steps to install a tow bar wiring system:
- Install the base plate while following that particular component’s instructions.
- Attach one end of the wiring kit’s wire setup to the baseplate of the towed vehicle.
- Move the wire to the back of the towed vehicle. Pay attention to where the wires pass through and avoid any locations that may hinder the connection.
- Once the wire reaches the rear, remove the tail lights of the towed car. Consult your owner’s manual if you don’t know how to remove these components.
- Connect the wires from the wiring kit to the tail lights’ electronics setup. At this point, it’s important to double-check if the wires became caught in something. If slightly tugging the wiring kit made you notice the existence of an obstruction, remove that obstacle before proceeding to the next step.
- Secure the new wiring setup in place. Pieces of quality double-sided tape should suffice.
- Reinstall the tail light.
- Repeat steps 4 to 7 for the other tail light.
- Connect the wiring kit to the diode system, which will allow communication from the towing vehicle to the towed automobile.
- Test the tail lights on the towing vehicle to see if the tail lights on the towed automobile activate.
Keep in mind that this installation process typically requires sufficient knowledge about electronics. It also needs a fair amount of confidence to ensure that the assembly works as intended.
If you feel that you're not confident or don't have the necessary skill to install this system, request professional help instead. Take note that expert services will typically demand a fee for the installation, which should be about $550.
