this came off a donor truck for a conversion I’m doing. The donor is a 61 straight from Japan so many other “different” things. Anyhow, what would this be used for and does anyone know who makes them? Thanks. Jim
Looks like a Toyota Hall effect sensor. In some early toyotas (Celica, MR2 etc) that still had a cable driven speedo that sensor was added "inline" to give a digital speed signal which is used for cruise control.
I believe some 60 vintage cruisers had cruiser control fitted at the dealer... I would guess that used this inline sensor to make it work.
That's effectively what I'm doing... adding a VDO cruise control module and using an inline adapter to get a digital speed signal.
If you need more info I can look up exactly what models had it and what the frequency of the Hall effect sensor is (have it written down).
