So downloaded this and traced all the wires on the back of the cluster - the colour of most the wires are different :( I think this EWD is for a USDM mr2 as I checked them against a Gen 2 cluster I have at home and they match up.
So again, anyone who has a 1990 ADM NA mr2 manual, please let me know ASAP...my car is in pieces atm lol.
