Trailer Wiring diagram 4 pin and test lights

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.

I'll try to remember that without the trailer the boat doesnt go anywhere duh. Thank you for showing how to test the 4 wire port connection.

Thank you so much ... hundreds of videos out there and not one simple HOW TO DO IT video. This video was absolutely perfect!!! Short, to the point, and super easy to understand. Wish there were more like this. God Bless and farewell.

This is a good video that explains trailer light wiring extremely well. Thank you.

If the tail-lights are LEDs the connections are "unidirectional"... so where does the brown wire go, and where do the green and yellow wires go? Or just try both ways and pick the one that works?

all 4 of my pins were turd pins. thank you helped out in a pinch 😀

So my boat is exactly like your video. My boat has a 3 male 1 female attachment. All the videos I have seen are the opposite and 3 female 1 male adapter. Does this matter? My truck was built to fit with this setup you've shown.
