The Ford wheel is approx 2.35” OD, the Dodge wheel is approx 2.1” OD. The Dodge wheel diameter is not compatible with the Ford sensor, at least they don’t seem to want to package together in the Mopar dizzy because the Ford dizzy is larger OD and the guts are bigger. Anyone that has a Ford and a Mopar dizzy, please see if you come up with any ideas on how to merge them.
The hurdle I’ve hit is that the Ford takes a 12V input, the Dodge Magnum info I have shows it takes a 5V input and the wire colors differ from the TBI Hall I have. I want to be able to figure out how to test it, then put 12v into it and see if it blows the sensor. Hall sensors usually have a wide input voltage range, and it’s conceivable that Dodge used 5V as it was a standard sensor voltage and Ford used battery voltage instead. The sensor might not care what we feed it.

Anyone have a Dodge TBI schematic for the Hall sensor??? I need to know the wire colors so that I can hook it up to my test meter. If this sensor can handle 12 volts, it might be the solution. There would still be some mods required, but we’ll cover that in the future if this sensor will work (job #1).



So it looks like the Ford wheel will fit inside the mopar distributor, and the main problem is finding a sensor that will fit, correct?

After looking at Wedgemans picture again, it sure looks more like an photo interrupter than a hall sensor. Is the white thing on the inside magnetic? Any wires going to it? I don't suppose there are any part numbers on the actual sensor on the mopar sensor?

I was just looking at Hall Sensors at Digikey for a different project, and yes, most of them have a very wide input voltage range. Or if it is optical, we just need another resistor in series to limit the voltage and it should work just fine at 12v.

If there's room, it may be easiest to put the ford wheel in the mopar distributor, then I can make a Hall Effect/Optical sensor that mounts to the mopar plate, like this one., Or we get a flat wheel cut out and mount our own sensor in the distributor

Anyone have an extra magnum distributor they want to sell me cheap? I have a Ford one I can pull and compare, but I don't think the junkyard here even has any magnums

If you ever find yourself in a fair fight, your tactics suck.
