I bought a trailer ( came with a Bass Cat on it – hahaha) and it had a bad taillight. It is a 2004 trailer and I ordered LED light replacements. I cant figure how to hook up because it looks like the plug into the existing taillight is different from the female receiver built into the LED light. Did I miss something when I ordered these off the parts site??? Also, I need the original manufacturers statement of origin to register the boat trailer in TN. Who would I call for this? Thanks
