Trailer Wireing

Question:
How many of you have had problems with your trailer wireing?
The reson I ask is because the way I have seen most trailers wired I cant believe that the trailer makers still wire the trailers the way they do. The way they connect wires is threw a
connector that is not water resistant or the even the correct connector. IMO all trailers should have a specific made wire harness with all soderd and shrink tubed connections not a spliced together harness.
To me it just seems that the trailer makers just throw a cheep wire harness on the trailer to get you down the road and not somthing that is made to stand the test of time.

I agree. I have already had to replace several lights and even the connection. Only had the boat two years. doesn't seem right...
