Just dont connect the yellow and green speedometer wire and see what happens. The stock redtop cutoff should be around 128 mph.
If you cut the wire you will still be able to see how fast your going because the circuit goes: Speed sensor>speedometer>ECU. So if you dont connect the speedo wire at the ECU the circuit goes speed sensor>speedometer.
