I need the plug extensioninch for the Curt Triflex brake controller. This is for a 2026 Ram 1500 Hurricane PU. I cannot find this on your website.

Thanks for reaching out, Daniel.

I did some digging on this, and unfortunately, Curt doesn’t currently offer an extension harness for the connection between the brake controller and the vehicle-specific pigtail.

For your 2026 Ram 1500, the vehicle-side harnesses, like the Curt Custom Wiring Adapter # C51446, are about 24" long with 12-gauge wire. If you’re planning to mount the controller farther away than that allows, the only option would be to extend the wiring by cutting and adding wire to the harness.

How much length were you needing the harness to be?
