I recommend using a Hopkins 5-Way Flat Trailer Connector # HM47913 for the 5 wires you have on your trailer. This connector has LED test lights built in to confirm power coming from the vehicle to help troubleshoot any issues in the wiring after connected. Typically the yellow wire will be your left turn signal/brake and the green wire will be your right turn signal/brake but you can use a 12 volt battery to test your wiring to ensure that it was connected the same way. This connector has the following wire colors for function.
Green: right turn signal/brake
Yellow: left turn signal/brake
White: ground
Brown: tail light and side marker lights
Blue: backup/reverse lights
These are the common wire colors for function but as I mentioned you can test them to ensure the function before attaching to the pigtail. You can also trace the wiring to individual lights on your trailer to see what color is going into each light to determine their functions.
