how is the vss signal form? how transform these in a readeable speed value.

this is made of flat pulses?

I wanna make a digital speedometer for my fit. But before i wish know somithing more about the way I will need to read the speed.


There is a way to get the VSS signal from the cables that plugs on the cluster? what wire?


Many Thanks!

 

5 volts per sensor flash.

Every car with different gar ratios has a different specific reading. can always log certain values at certain speeds and go from there.

 

do anyone have the cluster pinout?
there is a vss signal there? I want get the hi and low temps, and the parking break light from there.
