Have been troubleshooting a problem with running lights on trailer. Think I have isolated the problem to a loose hotwire on one of the marker lights resting on the trailer frame (causing me to burn a fuse in my truck).

In troubleshooting I have come across something that I can't figure out. Trailer has a 5-pin flat connector with a white, yellow, green, brown, and blue wire coming out of it. The trailer has corresponding white, yellow, brown, blue, and RED wires. I have no idea what the red wires power... as I cannot find anything that they attach to (I crawled around everywhere under the boat trailer looking). Currently, the Red wire(s) are tied in with the Blue wire (coming out of the adapter). Just want to make sure that this isn't going to cause a problem.

Any help is appreciated.

Thanks.
