Three wire Hall effect speed sensor (Posted for a friend)

[Mark Grady]

Hi folks.

Hopefully someone can help. 
I'm installing an engine monitor, and need a speed sensor.

I've got a sine wave generator type now, but my new toy 
(AV-10 engine Monitor) needs a Hall Effect type.

I'm hoping that someone can tell me what make/model of car might use that
type of speed sensor so that I can go find one at a local dealership. The
type I'm looking for goes inline with the speedo cable.

I actually have an extra sitting on the input side of the cruise control
which is no longer used (old EFI scheme) and that's where I'd like to put
this new Hall Effect sensor.

TIA -- Heinz
