Question:

I have a 2012 john Deere 5045d utility tractor with a trailer plug on it. I need an adapter plug to go to a four-way flat for lights on a simple trailer. It has a 7 pin male plug, like you would see on a 18 Wheeler

Helpful Expert Reply:

Due to your 7-pin connector not having combined tail lights and brake lights you will need to create an adapter using the following parts. The Pollak Heavy-Duty, 7-Pole # PK11700 will connect to your 2012 John Deere 5045d tractor. You will wire the Hopkins Tail Light Converter # HM48847 to this. The 5 wires from the converter will attach to the 7-pin connector as seen in the image below. Then you will be able to attach the Hopkins Endurance Easy-Pull Harness # HM48058 to the 4 wires on the other side of the converter. Since these are both Hopkins products you will be able to match the colors on the harness. The Deka Heat Shrink Butt Connectors # DW05743-5 will ensure a weather tight connection.
