      Look at your towing vehicle and determine what type of connection it has. These are available in 4-, 5-, 6- and 7-way connectors and each allows more functions to be transferred from your towing vehicle to your trailer.

      Put the correct lights into the correct brackets. Don't forget to put the wire through the bracket first then secure the light. Get all the lights attached before worrying about the wires.
