Question:
Hi, We have a 2016 magic tilt pontoon boat trailer. I am replacing the passenger side tail light. Problem: 3 ground wires come out of the trailer frame. I do not know what to do with these. I have a 4 pin harness. The new light had the instructions to ground to the frame attaching behind the lights screws. Any ideas on what to do with the 3 grounds. the driver side is working fine,

Expert Reply:
First, go ahead and follow the instructions and ground the light to the frame. After this is done, I would suggest grounding the other wires to the frame as well since you don't exactly know what they are coming from or what they are for. This is a safe bet and will prevent you from running into any issues.
