So i plug the pin in for the lights on my boat and nothing works. My car lights worked, but my trailer was dead. Anyone know if there is a switch or something or have similar problem? I ended up throwing it on my Landcruiser and the lights worked fine, so i know its not the trailer. The Landcrusier uses the same pin adapter too, so i'm lost here.

 

Blown fuse in the power line to the relay, if it has one, for the harness I bet, as I had one blow a while back on another vehicle.

 

maybe the connection is loose? I had this problem on mine.

 

Where you going with the boat without me??? Get to work....hehe.
