Wiring Needed to Add a Brake Controller on a 2013 Hyundai Santa Fe  


I had to remove my old Curt wiring harness as the fuse had severely corroded over the winter on my 2013 Hyundai Santa Fe and caused a short in the electrical system that created issues with the turn signals and brakes lights. The vehicle also has a Tekonsha brake controller. Weeks later I ordered a new harness 56332 but don’t recall which wire from the harness has to be spliced into the red lead wire coming from the brake controller. I’m unable to find the original installation video, or wiring diagram that explains this.


Expert Reply:

The Curt T-Connector # C56332 that you referenced actually doesn't carry the brake controller signal. It tees into your vehicle wiring and only carries the basic trailer lighting functions.

If you are trying to tie in a Tekonsha brake controller, like the Prodigy P3 # 90195, then you also need the Universal Wiring Kit # ETBC7. This plugs into the Curt T-Connector and comes with all of the wiring and parts needed for a fully functioning 7-Way. I have attached an installation video of the ETBC7 and P3 on a 2014 Santa Fe that you can use as a reference. Even if you don't have the P3 the installation will be the same. You will route the duplex wire from the 7-Way at the rear of your Santa Fe up to your cab where the brake controller is located.

Let me know if you were referencing something else and I can help you out further.
