Need whole new harness, where too look???
Hey guys, I've been having problems lately with lights not working on my dump trailer, turns out a bunch of wire had corroded in the harness. Now the lights are acting up again and the battery in the trailer no longer charges while driving. Also the brake controller doesn't work all the time either.

My harness is all corroded and i'm sick of fixing it all the time so i'm looking to pick up a new harness, the one that runs from the front of the truck all the way to the back. Ford told me $1200-$1500 depending on which on I needed.

Anybody have a idea on where I can get one.

The truck is a 01 f350 drw.

Thank guys

Are you sure they quoted a price on the right part? $1200 for a bundle of wires 20' long?
Maybe there is more to it than I think, but that sounds outraegeous!
