Where to Connect the Adapter to Install a Curt Brake Controller in a 2017 Nissan Pathfinder

Question:

Hey Jon , I found the connection on my Pathfinder thanks to you, but when I try to move the trailer the brakes are on. I had the same problem when I hooked up my prior Frontier and one of your technicians told me to swap Brake output and the 12 volt circuits on the trailer, but I don’t recall which colors the wires were ( I think one of the wires was blue. Could you kindly let me know.

To install a Curt Brake Controller, like the Discovery # C84VV, on your 2017 Nissan Pathfinder you will simply need to plug the Custom Wiring Adapter # C51382 under your dash like you mentioned.

I am attaching a video where one of our install guys installed a Tekonsha Prodigy P2 # 90885 in a 2013 Pathfinder using the Tekonsha Wiring Adapter # 3050-P. If you skip to the 2:45 mark you can see where he plugs in the adapter for the Prodigy P2. Your Curt adapter will plug into the same place.

The 12V Power wire is typically Black and the Brake Controller wire is typically Blue. The 12V Power should connected to the pin in the 11 o'clock position and the Brake Controller should be connected to the pin in the 7 o'clock position (see attached photo). I recommend using a Circuit Tester # PTW2993 to verify the functions of these pins before you start switching wires around. If this doesn't fix the problem just let me know and I can help you troubleshoot further.
