the one that has 6 blades around a center spot, I have tried 2 adapters and no luck yet. I just got one from Autozone that says its a 7 way to 4 or 5 pin adapter. My connector coming off the boat is a 5 pin. I get tail lights, trailer lights on the side of trailer but only the left side brake & turn signal works. The right side tail light works but no brake lights and no turn signal. Anybody got any idea where I need to start checking ? I have LED trailer lights, dont know if that will make a difference or not.

Here is the picture of the connector on the truck
