Also, from what little I could find on the 94-98 speedometers, the chip in question seems to have some programming with it. Being a Signetics chip, I was wondering about that. Seems I am probably correct. If I can get the chips in hand, they wouldn’t have the proper programming if they weren’t surplus NOS that Ford used. There were a few different speedometers in our narrow year range just in the year, engine, and max velocity, so finding even a NOS with the correct parameters is almost zero. I went ahead and just bought a same year/ model used cluster for mine today so I can get back on the road.
