71 Duster 360 turbo build
This is from my spreadsheet where I document all of my pin-outs and wire runs:
"Crank Cherry Hall Effect Sensor - Requires pull up resistor. This tees into both the supply voltage and the output signal wire. Use a 2.4K resistor when using 12v teed between the VREF and signal wire to pull this up."
As I recall, diyauto only sends a 1k resistor with the Cherry hall sensor. So if you are powering the sensor from a 12v feed, you'll need to buy and T-in a 2.4k resistor.
