JDM SiR Speedometer Signal 12V or 5V?
I am about to install a CRX SiR cluster.
All the sites I've read don't mention if the SiR speedometer is 12Volt signal or 5Volt.
Does anyone know?
The speed sensor on the trans has 3 wires, ground,signal and ?volts +.
My car is OBD1, I don't know if the P72 will be happy with only getting a 5volt signal.
I also don't want to burn up my speedometer motor by feeding it too many volts (12volts)
Has anyone ever done this that can chime in?
