Hi Guys,
Been fitting (trying to ) some gauges into my VR4. And when I was doing the " Air/Fuel Ratio Gauge, the instructions say that the purple/violet wire is to be connected to the " SPEED SIGNAL " wire. I also have to make a connection to the same wire for the Greddy Turbo Timer.
Has anyone come across this problem and know which pin on the ECU is the " SPEED SIGNAL WIRE "?
Even if the colour of this wire is known it can be helpfull?
Many thanks to one and all who can help me.
Gerald.
