I bought this one it worked with one trailer and now on my née trailer it’s doesn’t work. None of the little red lights light up. Do you know where the fuse for this is ?
I just bought a boat I need to know how many pins do I buy the plug for. The trailer has 3 female and 1 male. But the round one that plugs into my 2020 1500 high country does anyone know which one it takes ?
