The Spac Instrument cluster is not the digital one (Spac cluster has speedo, tacko, temp, voltage, oil pressure & fuel). If your car isnt around 89-90 or later, it will be more difficult than you think! I wanted to fit one in mine, and because mine is 88, it doesnt have any of the extra looms for wiring it up. Apparently you only have to run an accessories power wire to the cluster to get it working, but Im not sure what pin, or know anything else about it. Also, you may need a new Oil Pressure Sensor, if your oil light comes on with the new cluster, you will have to change it... Does anybody have like a Gregories manual to the EA? if so, that may have pinouts in it?
