Question:
How do you plug in your electric brakes and trailer lights and this sway bar with one 7 pin plug attached to vehicle ?

Hey Val, great question! The 7-way on your trailer plugs into the 7-way connector on the Curt True Course # C94VV. Then the 7-way wire that comes off of the True Course will plug into the 7-way connector on your 2025 Tucson. Everything passes through the sway control module so you only need the one connector on your vehicle.

I purchased a Geo Pro GFKS travel trailer which has dual axles and brakes and weighs 5000 lbs at 22 ft long. Immediately following my purchase I also purchased the Curt Electronic Sway controller and installed it. This device works perfectly and I can pull the trailer up to 75 mph with no sway at all. I recently took a trip and was traveling east to west with a 30 mph north wind and heavy gusts. The trailer never swayed once and I kept it at 65 mph. This is a must have if you trailer. Simple install and always ready.

Hi I am towing a Prolite 1400 lbs loaded that currently has a electric brake module that plugs into the dive and trailer plugs into that so are you saying it controls the electric brakes on the trailer and don’t need electric brake module ? Thanks val
