Hey Cory! The Blue Ox EZ Light # BLU55HR follows the standard for 4-way wiring colors. The white is ground, brown is tail, green is right turn/brake, and yellow is left turn/brake.
You can add a 6-way connector using the RoadMaster 6-Wire Trailer Connector # RM-910030-7. If you need a mounting bracket # RM-910030-5 is also available. I attached a diagram below which shows how to wire the connector for your reference.
