This is a basic wiring diagram for a 4 pin trailer configuration. If you would like to see a 7 pin, 6 pin or 5 pin configuration let me know in the comments below and I will work on it 👍

Btw for the white wire 98% of people ground ot to the frame like i did in the video. But the ultimate best way is to connect all the white wire to the withe wire at the trailer end connector to avoid bad ground that can cause blinking of your light.
