Oddly enough, that F-350 *is* starting to have weird electrical problems. They're not related to that *specific* oopsie there, but in a truck like an F-350 FX4 that costs the better part of $40,000, you'd expect them to spend the $1 that it would take to not allow moisture free access to the wiring harness.
My *XJ6* had better harness assembly than that. Says a lot when Lucas could build a better harness than Ford.

I had a '99 Ranger I put 120K on before trading it after 6 years and being just sick of looking at it. ;-) It never gave me any problems but the wipers would just wipe every now and again without being on. It might happen once every 3 or 4 months. No rhyme nor reason. You may have a point about Ford's wiring. That little truck was tough as nails, though.
