The speedo went out on my truck*. It seems to be a broken cable problem
and not a big deal. It seems that the cable is a 2 part system with an
unusual connector in between the 2 cables. It looks like it is some sort
of sensor for the cruise control. Long story short, the internals of
this sensor are frozen up and caused the longer of the two cables to
shear off the tip. The part in question doesn't show up in my manual,
but it has the Ford oval and D4AF-9E731 cast into it. I tried Googling
the number but got no hits. What is it?

Any suggestions on the fix? I does not appear to be easy to get into to
repair. Bypassing is going to take a much longer cable assembly and I
haven't a clue as what to use.

Since it isn't a common part and is kinda old it is probably an
expensive special order item. The other option is heading to a pick your
part wrecking yard and I was wondering what other Ford products this
sensor might have been used on?

TIA

Have you tried the auto parts store for a long cable housing? It might be
cheaper than you think.

I would imagine the sensor must be for cruise, but you didn't mention
whether your truck has cruise or not. Since the truck has a manual tranny
and a carburetor, it really couldn't be much else, could it?

Another option is Green Sales Co.....I think they have a website.
Anyway, these folks buy-up old dealer inventories and don't charge high
prices. I keep my '81 maintained and a few times I've needed some
pieces that I just couldn't find. This company had them. Another place
to look would be LMC truck. This company also carries OEM stuff for
older trucks. Also have a website.

Hope this helps.....

Thanks Dave and all, I will give Green Sales a call in the morning.
Hopefully they can figure out the part number.

Your part number is an engineering or casting part number and is not the
part number the replacement part would be sold under.

D4 = 1974, the part was designed for a 1974 project
A = Full size Ford Car
F = ? (probably an engineernig designation)
9E731 = speed sensor group P/N

So it seems like your item is some sort of speed sensor originally released
for a 1974 full size Ford car. This doesn't mean that it wasn't used on many
vehicles for multiple years, just that it was originally designed for a 1974
Full Size Ford. And the actual serive part number will be different than the
engineering P/N on the unit.
