This is only going to help you if you are using a Nissan Frontier (possibly other Nissan vehicles) as your tow vehicle. This wiring connects my truck to the Tekonsha brake controller I use for my tow system. This is specially built for the Tekonsha brake controller so DO NOT try to pair this with any other brake controller system.
Do you research before purchasing any wiring to make sure it is the proper fit. Tekonsha makes different connectors for different makes and models of vehicles.
If you have a Nissan Frontier in the 2005-2017 model range and wish to purchase, click the link below.
