Trailer lights: rear brake/blinker

[C-Bass2mouth]

While on this subject, does anyone know where I can get some re-wiring done on my bass boat for a reasonable price, or have an idea on a price to pretty much completely re-wire a boat? Have had the tarp over it since June, and recently noticed the plug was still in...and that the cover had slid off on one corner, so the entire boat held water for a while and pretty much every connector is corroded away on the batteries and on the switch board at the console. Not sure if I should run all new wire or just splice and put new connectors?

Btw be careful of your buddies truck when hooking up the lights, I had some transmission problems one day this spring so we took my buds truck and promptly pulled the whole thing off after the first sharp turn bc his hitch was further from the truck than mine...
