t56 speedometer logging

Does anybody know what the speedometer output is for a t56. Is it a resistance or a voltage or a pulse? I want to log the output
Thanks

It's a pulse, but it IS affected by tire size and gear ratio. I believe it's like 17 pulses per driveshaft rotation, but don't quote me on that.
