Actually this is an 280 km/h - 10000 RPM STI V5 Cluster swap to a MY98 car. I have donor MY99 car and I have already cut the 3 three green connectors and rewired everything. It works except the Speedometer and Water Temp.
Water temp gauge rises to the top and the speedometer is not moving. I'm gonna upgrade to an MY99 electrical Vehicle Speed Sensor and I believe it will solve the problem. I cant change the coolant sensor because the ecu will retard the ignition but I may put a secondary MY99 coolant sensor.
Any inputs will be appriciated.
