Question:

I like the wiring harness for under the dash connector on my 2025 Nissan Pathfinder with a tow package. I already have this controller. I just need to plug it in under my dash. https://www.etrailer.com/Trailer-Brake-Controller/Tekonsha/TK90160.html

Hey Tom, for your Tekonsha brake controller to install in your 2025 Nisssan Pathfinder you would want the install harness part # C51382 which plugs into the port under your dash. You would need to cut off the Curt side of the connector and wire it by color to the Tekonsha universal harness since we don't have a Tekonsha harness that fits your vehicle at this time.

Hey Tom, how did the installation of your Tekonsha brake controller go with the Curt wiring adapter? I'm curious to know if the solution worked well for you, as it could help others in a similar situation!
