Hi Robert!
We have a couple options for a 25' long 4 flat. Our site can be weird sometimes, but not sure why it isn't showing you more options.
Anyway, the Mighty Cord 4-Way Flat Trailer Connector - Wishbone Style - Trailer End - 25' Long # A10-4225VP will be the "basic" 4 flat and the Hopkins Endurance Easy-Pull Harness with 4-Pole Flat Trailer Connector - Trailer End - 25' Long # HM38136 will be the "fancy" option. Both are 25' long 4-flat trailer end wiring harnesses, but the the Hopkins has an Easy-Pull loop to make unplugging it easier. It is a couple bucks more expensive, but it really does make unplugging easier.
Did you wiring get corroded or did you have a break somewhere and decide to replace everything?
