7 flat blade pin & trailer brake controller installation

[nm75081]

I need to install a 7 flat blade pin connector for lights and electric brakes on a 14' utility trailer. I'm searching for a simple solution, hopefully involving a plug and play jumper. The image is of a connector located under the rear bumper on the driver side. Any pointers would be greatly appreciated. Thanks! nm

They make ready-made plug n play trailer harnesses that plug in there. Northern tool is a good place for that stuff.
