Trailer - Fix or Replace?

[bigdog]

Just checked trailer wiring of used trailer purchased with boat, and the wirig appears to be cut or snapped from where the pig-tail plug enters the trailer tongue. I know nothing about the rest of the wiring, inside the trailer, haven't reviewed condition. I did have to replace a broken tail-light. For all I know the rest of the wiring could be junk ? FYI, trailer camme from
salt-water location, and you know what those climate condition cause....

Question.... In an effrot to save time and trouble, do you think it would be easier to try to fix the current wiring, or just replace with new, from front to rear? I think I know your answer !

Also, if new wiring is to be replaced, from to rear, I was going to bypass the side-reflector lights which are currently wired, and just use as reflectors.
This would eliminate a lot of extra wiring now, and problems down the road.

Your suugestions are always appreciated !
