I put all new trailer lights and wireing on my Boat trailer. Lights work, turns work. I am pluging into an adapter 7 pole to 4 pole and 5 pole. When I have the lights on and put on the brake the lights go out. When I turn off the lights and put the brake on the Lights work. What am i doing wrong? The only thing I did not do that I saw in your videos is I did not sand off the paint, and rust. Could that be it? Thanks for your time and Videos Please help
