To install the Curt Venturer part # C84VV in your 2016 Nissan Frontier requires the install harness part # C51382 which is a confirmed fit. In a lot of cases the wire colors don't always match up perfectly as sometimes the manufacturers will change wire colors or they use all-together non-standard colors but we know the harness mentioned is the correct one for your Frontier.
Since you have a horse trailer and the brakes are locking up I suspect the issue is related to the trailer connectors. There are two standard ways that a 6-way (what is typically seen on a horse trailer) can be wired and the only difference is that the 12 volt accessory and brake output circuit are swapped. I would be willing to bet you would just need to swap the brake output and 12 volt circuits and the brakes would stop locking up.
I attached an install video for you to check out as well.
