VR or Hall? What type of engine is this on again?

To be honest, I do not have an answer. I wonder if at least the first one is optical?

1996 Ford Aspire http://en.wikipedia.org/wiki/Ford_Festiva#Ford_Aspire

Very familiar (no pun intended) with the Mazda B3 and B5 engines, however all of the ones I thrashed the living shit out of had carbs. Take some photos of the physical parts showing the thing that actually drives the wires, IE, the slotted wheel, or hall vanes, or toothed wheel, etc.

I will go to a junk yard and take one distributor apart this weekend, I guess that would be a great learning experience.
PS: first I would need to trace where these three wires actually go

[Fred]

LOL! Tracing the wires is usually my FIRST step, then hooking them up ;-)

Here you are. It's 1995 Aspire distributor on these pics (mine is 1996, they have converted from non-OBD2 to OBD2 so something could be different, but probably still in the same ballpark)

If it is the same, your diagrams are totally wrong :-) Maybe you didn't have pullups on your inputs? Clearly only two signals, as well. That pattern is very easy to handle. Enjoy.

Part catalogs tell me it is the same part. Weird.

Actually, the large ring is probably the signal I am currently handling - it is the "XXXX___XXXX___XXXX___XXXX___" is not it?

What kind of sensor is that?

[Fred]

It's classic mazda/mitsi hall effect. The inner ring is usually different, though that matters little.

Sequential ignition is implemented - now I need to re-solder everything nicer.
