I think you need to check for the signal for the RPM in a Brown coloured wire. If the same is present in your stock wiring, a direct swap is possible (which I doubt). Else, you would have to make a connection from the wiring present under your dashboard (consult a technician) from the Brown coloured signal wire and make a connection to your new speedometer (with the tachometer)!
