Hello, I am wiring up an aftermarket gauge cluster (koso rx2n) and I need to know a few things about the VSS signal waveform coming out of the ECU A18/ C101 pin3 for the speedometer.

What is the peak voltage?
What is the frequency in relation to vehicle speed (I just need a general ball park figure)?

The ECU does not output this signal. This is an input from the VSS sensor on the transmission.

So is it a 12v peak waveform?

Edit: Nevermind I just found it... its a 5v pulse.
