Question:
2025 Tacoma, 4th gen, need electric trailer brakes. No connector for brake controller. Truck came with 4 and 7 pin connectors. Toyota dealer says no help at all. Will there be a wiring kit for trailer brake controller?

Expert Reply:
There is a wiring kit for a brake controller Preston but it's not going to be a plug and play one. The 2025 Toyota Tacoma does not have a plug in brake controller port. Toyota stopped putting them in after the 2023 model.
For your Tacoma, I recommend the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness item # RED52VR. This is a proportional brake controller that activates your trailer's brakes when your Tacoma decelerates.
The reason the Tow-Pro Liberty is the best option is because of its unique installation method where the only visible portion is the control knob that's about the size of a nickel. The main unit is hidden away inside your dash to be completely out of the way and out of sight. This kit includes a universal harness to get the brake controller installed.
Additionally, we do have a custom mounting method for the control knob since you're installing it in a Toyota. You can use the Mounting Panel for Redarc Tow-Pro Trailer Brake Controller Control Knob item # 331-TPSI-002, in one of your empty knockout panels.
What kind of trailer do you have?

Can't say it looks straight forward. Looks like short wires. I pull a 2.5 ton rated utility trailer with compact tractor. Flat land and try to avoid heavy traffic. Not impressed with what I see on the web page, and don't like the wireless Curt. At 65 years old, not excited about taking a new truck apart to wire.
