Greg,
Thank you for you indepth repair instructions.
I just purchased a used 99 F150 Supercab Lariet 4X4 78,500 miles with the identical problem. The previous owner was upfront with me concerning the intermittent odometer that plagued him for a few years.
Upon inspection per your instructions I found the identical circuit board terminal with a cracked weld(solder). Your right it was difficult to see with the naked eye.
Works great now. Thank you for saving me a lot of time.
Mark
